Definitions

  • the invention relates to a discharge device for one or more media, at least one of which is not gaseous, e.g. liquid, powder or the like and / or at least one gaseous, e.g. Air that can be.
  • the discharge device can only be formed by a discharge head for attachment to a pressure generator, such as a push piston pump, a squeeze or bellows pump or the like, or it can form a structural unit with such a pressure generator or an associated media store.
  • the discharge device has one or more media outlets, outlet channels, volume-variable chambers for manual pressure generation, valves or flow-changing actuators or the like, which guide the medium as soon as the pressure chamber is narrowed by direct manual actuation or by pressure chamber charged before actuation under delivery pressure the manual actuation to the outlet duct is opened.
  • the media flow can be influenced during the course of a single discharge process in order to adapt to changes in the delivery pressure, or it can be influenced in order to achieve the most accurate possible metering of the discharge quantity per discharge process.
  • the invention has for its object to provide a discharge device in which disadvantages of known designs avoided or compared to these advantages, e.g. Advantages of the type mentioned are to be achieved and which, in particular in the case of a simple design, enables the media flow to be influenced as desired after leaving the pressure chamber at any point between this pressure chamber and the media outlet adjacent to the outside.
  • a core or other actuating body for changing the media flow can be provided in such a way that, as the delivery pressure increases due to a movement, a restriction or the like of a passage cross section or a subsequent further movement is possible.
  • the passage cross section or the further movement can be changed by a separate manual actuation in such a way that the respective setting is retained regardless of the actuation or of the delivery pressure and / or it can be path-dependent on the actuation or pressure-dependent, namely automatically as a result of the aforementioned Discharge actuation of the discharge device may be provided.
  • At least one media outlet is formed by a relatively narrow nozzle of less than 8, 4 or 1 mm, in particular by an atomizer nozzle, the flow paths of which form a nozzle geometry which influences the flow behavior, so Regardless of the design described, an actuator for changing this nozzle geometry can be provided so that passage cross sections of the discharge nozzle can be changed. The changes can always leave passage cross sections free or also completely close the outlet channel so that at least one medium is blocked against access to the medium outlet.
  • the actuating body can also serve to change the flow geometry and therefore the flow-influencing effect of a swirl or swirl chamber in which separate media for mixing or the like are brought together or converted into swirled or rotating flows.
  • an actuating body can have an essentially flat or at most flat obtuse-angled end face or control surface adjacent to an inner and / or outer circumference, which can be moved by the actuating movement relative to a correspondingly designed counter surface and, with this, delimits a disk-shaped, flat, but variable passage gap .
  • a longitudinal channel which adjoins the outer circumference of this passage gap can remain essentially unchanged or changed by the actuating movement with regard to its flow-influencing effect or its passage cross-sections.
  • passage cross sections which are spaced in the conveying direction or immediately following one another and can be changed by the actuating movement, are provided and are changed in opposite directions. If one passage cross section is enlarged or if it causes a quieter flow, the other is expediently reduced or if it causes a more turbulent or faster flow and vice versa.
  • the arrangement is advantageously provided that when discharge is conveyed, the first passage cross section is increased in flow direction and the second is narrowed, or that the reverse movement occurs in the return movement.
  • the path of an actuator from the starting position to the end position can also be used for metering or limiting the discharge quantity or for ending the discharge despite actuation of the discharge device and therefore the delivery pressure prevailing in the pressure chamber, although e.g. a pressure-dependent opening exhaust valve is fully open.
  • an expanded, annular or disk-shaped intermediate chamber is expediently provided between the valve seat and a narrow flow channel connecting in the direction of flow, into which the medium enters directly from the valve seat and into which the valve or actuating body can also penetrate.
  • Such an intermediate chamber or another chamber can also be designed as a pump or displacement chamber which can be changed in volume by an actuating body and from which the medium is displaced when the actuating body moves, so that additional conveying energy is thereby caused.
  • an actuating body can cause the media discharge to begin suddenly with the maximum discharge energy and / or to be stopped suddenly, so that there is not a slowly increasing or decreasing discharge, but rather a sudden discharge of the medium.
  • This is particularly advantageous for a finely atomized discharge in order to also ensure the finest atomization at the beginning or end of the discharge.
  • the media outlet can also be formed by a foam nozzle, in the area of which a foamable medium is foamed, possibly with the addition of gas, wherein the foam formation can be influenced by an adjusting body.
  • the actuating body can be driven by a piston or the like via an intermediate drive, but it is expediently connected to this piston rigidly or in one piece, so that it is inevitably, simultaneously or synchronously carried along and results in a direct mechanical drive.
  • the actuating body can be formed by the piston and this by a valve body.
  • An actuating body can have any of the configurations and effects mentioned in any combination or separate actuating bodies can be provided for this. It is particularly useful if the actuating body with a bearing, a valve seat, a return spring, a piston or valve body, a closure for the pressure chamber or the like., Forms a preassembled module which is subsequently attached to the housing forming the pressure chamber, the one Media outlet having discharge head or the like. To be mounted and expediently clamped between the last two modules mentioned.

  • this second medium having a different physical state than the first medium, e.g. can be gaseous.
  • the atomization or foaming can be substantially improved or the supply of the second medium to the media outlet or the like can begin before the corresponding supply of the first medium or can end after the supply of the second medium has ended.

  • the container 4 is a squeeze bottle yielding resiliently by manual external pressure on the jacket and / or at least one end face with flexible plastic walls, but can also be dimensionally stable or contain a propellant that generates the delivery pressure, such as an aerosol.
  • the container 4 forms a type of balloon pump, the pressure chamber 8 of which is formed by the storage space for the entire media supply can be changed in volume manually.

  • the pressure chamber 9 is refilled with air from the outside in such a way that the pressure chamber 8 does not take up air, regardless of its filling state, but is always full. Delivery of the first medium from the pressure chamber 8 or subsequent resetting of the container walls leads to a corresponding enlargement of the pressure chamber 9 with simultaneous air intake from the outside.

  • the circumference of the nozzle opening 53 is delimited by a tear-off or ring edge 52 which is sharp in cross section and which is delimited on the inner circumference by the channel 51 and on the outer circumference by the conical outer surface of the projection 48.
  • the end channel 14 is continuously extended in the shape of a truncated cone from the inner to the outer end 16, and the width of its inner end 15 is greater than the width of the nozzle opening 53, which is axially aligned with it and upstream at a distance therefrom.
  • the pre-atomizer formed in one piece with the base body 2, like the end channel 14 Nozzle 50 assumes the same position with respect to end channel 14 in every operating state.
  • the inlet end of the channel 51 facing away from the nozzle opening 53 opens into the valve seat 28.
  • the valve 17 opens increasingly, while at the same time the valve 18 associated with the inlet of the nozzle 50 increasingly closes.
  • the chamber 35 opens approximately on the entire axial extent of the outlet channel 12 in the manner described radially and / or tangentially, so that the second medium around the projection 48 is set into an annular rotational flow into which the first medium sprays out of the opening in the center 53 occurs in the gap area formed between the surfaces 30, 52, which causes a strong acceleration of flow.
  • the first medium can have an identical or opposite rotational flow.
  • the media mix from the area of the opening 53 are swirled again strongly as they flow along the inner ring edge of the inner end 15, which is also sharply flanked at an acute angle, and emerge at the media outlet 13 as an even more atomized spray cone.
  • the pressure chamber for the respective outlet channel 11 or 12 can also be formed by the cylinder space of a manually operated thrust piston pump that has to be filled repeatedly during the return stroke from a separate media store or from the atmosphere by suction through an inlet valve.
  • a manually operated thrust piston pump that has to be filled repeatedly during the return stroke from a separate media store or from the atmosphere by suction through an inlet valve.
  • two e.g. separate pumps or pressure chambers with the same axis can be operated simultaneously with a common handle.
  • any feature of any of the embodiments may be provided in any of the other embodiments.
  • the properties mentioned, such as sizes, relative positions, effects or the like, can be provided exactly as described, differing slightly therefrom or essentially as described or more or less deviating therefrom, depending on which discharge characteristics are desired or which properties, in particular flow properties have the first and / or the second medium.
  • Components or arrangements 1 to 53 can also only have one of the functions or effects mentioned.
