Definitions

  • the present invention relates to fluid dispensers for example to high pressure dispensers for introducing a fluid, such as soap, from a reservoir into a main stream of fluid passing through the dispenser.
  • a fluid such as soap
  • Dispensers which introduce and dispense in a main stream of high pressure fluid a second fluid, such as soap or detergent, or other chemicals mixed in a liquid solution.
  • US Patent Specification No. 4 369 921 discloses a liquid dispenser having a housing supporting and chemical content jar and a rotary control valve.
  • the rotary control valve is located in a main through passage in the housing.
  • the valve is selectively positionable in three positions. In a first position it allows the free flow of liquid through the main passage. In this position chemical in the chemical jar is drawn by venturi action into the liquid flowing through the passageway. In a second position it blocks all liquid flowing through the through passage and in the third position is also blocks liquid flowing through the passage but also diverts the liquid to the chemical content jar so as to disolve or dilute any chemical freshly introduced into jar.
  • all liquid dispensed by the dispenser contains a proportion of the chemical in the chemical content jar and a control is provided for varying the proportion of chemical to the liquid flowing through the valve.
  • Soap dispensers are commonly used for introducing soap into a stream of water which is dispensed by a nozzle or is used to drive a water wheel in a rotary scrub brush.
  • the devices in the above patents involve a housing, a ball valve rotatable in the housing and a main passage through the housing and the ball valve.
  • An auxiliary passage extends from an upstream portion of the main passage through the housing, to a secondary fluid reservoir at the bottom of the housing, then through the housing, back to a downstream portion of the main passage.
  • a disc held on the end of the ball valve by a fragile plastic clip closes and opens the openings to the reservoir in the auxiliary passage.
  • O-rings two in all, are required; one placed around each of the openings so that the valve member can close off the auxiliary passage. Also, due to the fragileness of the clip, repeated or improper use of the clip may break it. Additionally, two O-rings are required; one above and one below the main passage, for sealing between the top ball valve and the housing in which it rotates.
  • a fluid dispenser for a source of high-pressure fluid and a further fluid comprising: a housing having a first side and a second side the second side comprising means for coupling to a container forming a fluid reservoir for a said further fluid; a valve cavity formed through the housing from the first side to the second side; a cylindrical valve rotatably mounted in the valve cavity; a main passage formed through the housing and the valve substantially transverse to the valve cavity; means for coupling an upstream portion of the main passage to a high-pressure fluid source; an exposed control knob located at the first side of the housing and connected to the cylindrical valve for holding the valve in position with respect to the housing at the first side and for rotating the cylindrical valve; an "O"-ring for forming a fluid seal between the housing and the cylindrical valve towards the housing first side with respect to the main passage; an auxiliary passage extending from an upstream position in the main flow passage to the reservoir and back to a downstream position in the main passage with respect to the upstream position characterised by
  • the present invention allows the grooves within the reservoir to be closed off without the need for gaskets or O-rings as discussed in US Patents 3,447,753 and 3,770,205.
  • grooves are placed down the valve cavity between the cylindrical valve and housing to allow the openings to the reservoir to be positioned at the minimum radial distance from the centre of rotation of the cylindrical valve and closely adjacent the outer edge of the valve cavity.
  • the force required on the cylindrical valve to ensure a good, tight seal between the bottom side of the housing and the valve member is minimised.
  • the closing of the auxiliary passage may be accomplished by the valve member sliding against the bottom surface of the housing itself, without the need for O-rings.
  • This construction also minimises the structural strength needed and therefore the amount of material needed for the valve member. Additionally, structural strength is enhanced by moulding the cylindrical valve and valve member as an integral plastic part without the need for clips.
  • the fluid dispenser has a housing having a top side and a bottom side.
  • the bottom side is for a coupling to a container forming a fluid reservoir.
  • a valve cavity extends through the housing from top to bottom sides.
  • the cylindrical valve is insertable into the valve cavity from the bottom side.
  • a valve member is formed integrally as a unit with the cylindrical valve and extends outwardly beyond the valve cavity into closely spaced opposed relation with the housing bottom side.
  • a main passage extends through the housing and cylindrical valve substantially transverse to the valve cavity. Means is provided for coupling the upstream portion of the main passage to a high pressure fluid source.
  • An exposed control knob is connected to the cylindrical valve at the top side of the housing for manually rotating the cylindrical valve and for securing the cylindrical valve, relative to the housing, so that the substantially opposed relation between the housing bottom side and valve member is maintained.
  • a groove is provided around the cylindrical valve in the valve cavity.
  • An O-ring is provided in the groove forming a fluid seal between the housing and cylindrical valve toward the housing top side from the main passage.
  • An auxiliary passageway extends from the upstream main flow passage, through the reservoir, to the downstream flow passage.
  • the first, second and third rotational positions discussed above block the flow of high pressure fluid through the main passage, passes the high pressure fluid through the cylindrical valve and in addition shunts a secondary flow of high pressure fluid through the auxiliary passage including the reservoir and passes the high pressure fluid through the main passage while blocking the secondary flow of fluid through the auxiliary passage block by the valve member.
  • the auxiliary passageway comprises an upstream passage extending through the housing in a direction transverse to the main passageway, through a passage in the valve member into the soap reservoir; and a downstream passage extending from the soap reservoir through another passage in the valve member, through a passage in the housing, transverse to and ending in the downstream main passageway downstream of the valve cavity.
  • the alternate embodiment with the addition of O-rings around the upstream and downstream passages through the main housing has the advantage of requiring less exacting tolerances for valve and housing construction. Additionally, because the auxiliary passageway is less complicated, manufacture of the ball valve is easier.
  • the number of parts can be minimised and performance improved over the prior devices.
  • the total number of parts can be reduced to only three injection moulded parts and a total assembly of eight parts as compared with four and ten, respectively, in the above prior art devices.
  • placing an O-ring in a groove around the cylindrical valve above the main passage allows the O-ring to rotate with the O-ring reducing the frictional forces between the knob and O-ring which otherwise occur if the O-ring did not rotate with the knob. Also, placing an O-ring around the main passage at the upstream side of the cylindrical valve, between the housing and cylindrical valve, reduce pressure build-up in the reservoir when the valve is turned off.
  • soap dispenser 10 has a handle in the form of a conduit 12 connectable to the discharge end of a standard hose (e.g. garden hose), which provides a high pressure flow of water or fluid through the soap dispenser.
  • a male threaded connector (not shown) on the hose is connected to an internal threaded connector 14 at the left end of conduit 12.
  • the right end 16 of the conduit 12 is slipped into and locked by detentes on the intake end 28 of housing 18, which is detachably connected to a reservoir 20.
  • Conduit 12 leads to the intake end of a main passageway 22 which extends through the housing 18 and a cylindrical valve 24, located in the valve cavity 26 portion of the housing.
  • the passageway 22 will not extend through the housing and cylindrical valve 24 unless the cylindrical valve 24 is properly positioned.
  • An O-ring 31, made of rubber or like material, is positioned at the end portion 16 of the conduit 12, and ensures against leakage of water between the intake tube 28 and the conduit 12.
  • the discharge end 30 of the main passageway 23 is sized to snugly receive the extension of an intake tube (not shown) of a water wheel driven, rotary scrub brush.
  • the discharge end 30 has external threads 33 for threading into internal threads of a connector (not shown).
  • the housing has a ring-shaped flange 32 at its underside, for connection to a co ntainer 20, which together form a reservoir for a fluid or other material to be dispensed.
  • the container 20 will be connected in such a manner as to ensure easy disconnection, as for refilling in the "off" position, and a leakproof fit when connected to the flange 32.
  • the container has external threads 38 to receive internal threads 39 on the flange 32, at the bottom side of the housing 18.
  • the container 20 is moulded to receive and hold an O-ring 19 of rubber or like material, and ensures against leakage of water between the container and flange 32 when the container 20 is fastened to the flange 32.
  • a control knob 40 enables an operator of the soap dispenser 10 to directly effect the positioning of the cylindrical valve and thus control the main passageway 52, through the cylindrical valve (Fig. 1), and an auxiliary passageway 65 (Fig. 4).
  • the control knob 40 is a circular disc-member which has conveniently placed on the top side markings which indicate "off", “soap” and “rinse” positions, as illustrated in Fig. 2.
  • the control knob 40 is mounted in any conventional manner to the top side of the cylindrical valve 24.
  • a standard screw 42 is used to secure the control knob 40 to the top end of the cylindrical valve.
  • the control knob 40 is preferably large in diameter and extends past the edge of the housing 18, in order for the operator to get better leverage and grip for positioning the control knob 40 and cylindrical valve.
  • a detente is provided in the upper part of the housing, below the control knob, to provide a slight resistance in the "off" position, for a mechanical indication of the "off" position.
  • high pressure fluid such as water flows through the main passageway 22, which extends through the upstream portion of the housing 18, to an orifice 46 leading into the valve cavity 26.
  • This cavity is cylindrical in shape, and contains the cylindrical valve 24.
  • O-ring 50 preferably made of rubber or like material, seals tightly against and conforms to the outer side of the cylinrical valve in the valve cavity. The O-ring 50 helps to seal off intake water from the valve cavity 26 and the main passageway 22, when the cylindrical valve 24 is in the "off" position.
  • the main passageway 22 extends diametrically through a central portion 52 of the cylindrical valve 24, so that the main passageway 22 allows flow therethrough when the control knob 40 is in either the "rinse” position (Figs. 1, 3) or the “soap” position (Figs. 6, 7).
  • an upstream portion 54 of the main passageway 52, through the cylindrical valve has a large diameter; for example, of 3/8 inch, and a downstream portion 56, for example, of 1/4 inch. Accordingly, in Fig. 6, when the control knob is rotated 180° to the "rinse" position, the upstream portion 54 and downstream portion 56 are reserved.
  • the cylindrical valve 24 has a smooth, cylindrical, wall surface 43, which is about the same size as, but slightly smaller than, the cylindrical-shaped valve cavity 26 and freely rotates within cylindrical valve cavity 26.
  • a substantially watertight seal is formed between the O-ring 50 and the surface of the cylindrical shaped valve.
  • the cylindrical valve 24 has two orifices 64 and 66 at the ends of two passageways 58 and 60 that extend from the upstream and downstream portions 54 and 56, respectively, of the main passageway 52 through the cylindrical valve 24.
  • a disc-shaped valve member 63 extends from the cylindrical valve outwardly beyond the valve cavity 26 abutting with the flat side 41 of the housing.
  • the valve member together with the cylindrical portion 49 of the cylindrical valve 24 are integrally moulded together as a unit, so that, when the control knob 40 is rotated, the valve member 63 rotates as well.
  • Provided through the valve member 63 are two ports 74 and 76 which control passage of fluid through the auxiliary passageway 65 extending from the main passageway 52 (Fig. 3).
  • the auxiliary passage 65 includes grooves 68 and 67 extending longitudinally along the wall surface 43 of the valve cavity 26, radial grooves 72 and 70 on the bottom side 41 of the housing and upstream and downstream passages 58 and 60.
  • Rotation of the valve member 63 and the control knob 40 are limited by a circular stop wall 80 protruding from the bottom side of the housing 41.
  • the circular stop wall 80 circumferentially surrounds the valve member 63 for, preferably, 90°.
  • the valve member 63 is provided with an abutment 81 extending diametrically beyond the stop wall 80, and circumferentially around the valve member for, preferably, 90°. Together, the abutment and stop wall limit rotation of the valve member and cylindrical valve to only 180° rotations from the "soap" and "rinse" positions.
  • valve member 63 In the "soap" position (Figs. 3, 4 and 6), the two ports 74 and 76 register with two reservoir grooves 70 and 72, respectively, of the auxiliary passageway 65 at the bottom of the housing 41.
  • the top side of valve member 63 is forced up against the bottom side 41 of the housing 41 by a spring in the form of a wavy washer 61 located between the bottom surface of the control knob 40 and the top side of the housing 26.
  • valve orifices 64 and 66 align with upstream housing groove 68 and a downstream housing groove 67, respectively (Fig. 4). These grooves are located between the valve cavity 26 and the cylindrical valve. Preferably, the grooves are moulded entirely within the wall surface 48 of the valve cavity 26. Each groove extends down to separate openings or reservoir grooves 70 and 72, respectively, in the surface of the bottom side 41 of the housing 18 (Fig. 5).
  • the control knob is in the "soap" position, the upstream and downstream portions of main passageway 52 through the cylindrical valve 24 are remotely connected to the reservoir 20 by the auxiliary passageway 65.
  • the present invention allows the opening or reservoir grooves 70 and 72 into the reservoir 20 to be closed off without the need for gaskets or O-rings to be attached to the grooves.
  • grooves 68 and 67 are placed down the surface of the valve cavity to allow the grooves 70 and 72 to the reservoir 20 to be positioned at the minimum radial distance from the centre of rotation of the cylindrical valve and closely adjacent the outer edge of the valve cavity.
  • O-ring 47 is positioned in a groove in the cylindrical valve between the top end of the cylindrical valve and the knob 40.
  • pressure in the main passage will tend to lift the knob and cylindrical valve and enhance the seal between the upper surface of disc 63 and the bottom surface 41. In this way, the seal between the openings or grooves 70 and 72 are enhanced.
  • the positionng of the O-ring 47 between the knob and cylindrical valve has a significant advantage over placing the O-ring in a groove at the top side of the housing.
  • the control knob 40 would have difficulty sliding against the O-ring when the O-ring is under pressure.
  • the O-ring is placed in a groove at the top side of the cylindrical valve so that the control knob, the cylindrical valve and the O-ring rotate together, even under pressure.
  • the control knob When the control knob is turned to the "soap" position, the high pressure in the upstream portion 54 of the cylindrical valve 52 and low pressure at the downstream portion 56 are effective to shunt a stream of water through the auxiliary passageway 65.
  • the diverted water leaves the main passageway 22 at an upstream high pressure location and re-enters the main passageway 23 at a downstream low pressure location.
  • the diverted fluid flows in the auxiliary passage 65 through passage 58, port 64, housing groove 68, reservoir groove 72 and through port 76 to the reservoir 20 in the auxiliary passage 65 through port 74, reservoir groove 70, housing groove 67, port 66, passageway 60 and into the downstream portion 56 of the cylindrical valve 24.
  • the soap dispenser may be used with or without soap. If depletion of the reservoir occurs, the reservoir can be refilled with soap by turning the control knob 40 to the "off" position, disconnecting the reservoir from the housing, refilling it with soap, and reconnecting it back into the housing.
  • the invention is also expected to be useful with other materials such as waxes detergents or insecticides and the like.
  • the housing including its cavity, passages, grooves, control knob detentes assembly, detentes and the cylindrical valve, including its valve member, passages, ports, splines and O-ring grooves, control knob including its spline, and container are all individually injection moulded as a unit to form individual, easily assembled, plastic parts, as described.
  • Assembly is achieved by placing O-rings 50 and 47 in their respective grooves in the housing and cylindrical valve 24, by inserting the cylindrical valve 24 with O-ring 47 through the valve cavity from the bottom side 41, until the valve member surface 63 abuts the bottom side 41, by placing the wavy spring washer 61 around the cylindrical valve 24 on the top of the housing 18, by inserting the control knob 40 on the top end of the cylindrical valve 74, and wavy spring washer 61, by theading the screws through the control knob 40 into the upper end of the cylindrical valve 24, and by connecting the container 20 with O-ring 19 into the bottom side of the housing 18.
  • Figs. 10 and 11 depict an alternative embodiment of the invention. Identical reference numerals indicate identical elements disclosed in Figs. 1-9. New reference numerals are used to indicate additional components.
