Definitions

  • the invention relates to a manual shut-off gun for High pressure cleaning devices according to the generic term of Claim 1.
  • Such hand shut-off pistols are used to the high pressure medium generated in a pressure washer controlled in feed a spray tube at its free, front end a high pressure nozzle is arranged.
  • the aim is that a relatively sensitive actuation of the shutdown device is achieved, which is very difficult to achieve. Due to the cramped housing conditions in the housing of the manual shut-off gun for the installation of such a shutdown device mostly no satisfactory, sensitive shutdown or Actuation reached. It depends on one the greatest possible valve lift of the shut-off valve ensure the valve ball that the flow regulated, as far as possible from their valve seat can.
  • the requirement that the Flow resistance and the pressure drop upstream and be kept as low as possible downstream of the valve ball should, and moreover, the actuating force for the Actuation lever should be as small as possible, with a relatively large one Actuation path to enable sensitive regulation.
  • the pulling force is the pulling force that you have to exert in order to lift the ball from the seat, it should be as small as possible, as well as the holding force required to hold the Keep the operating lever in its open position.
  • this manual shut-off gun is also not by inserting the HP hose into the handle sufficiently balanced, which makes handling difficult and thus leads to faster fatigue of the user.
  • the kink protection is also in the manual shut-off gun imported HD hoses are not optimal, because of the Entrance area of the housing no corresponding constructive Features and thus an additional kink protection must exist outside the gun.
  • the present invention is therefore based on the object a manual shut-off gun of the type mentioned above to further train that the above claims account the risk of injury to the user is minimized will, the handling, maintenance and repair of the Manual shut-off gun is facilitated and the Susceptibility to wear of the inserted HD hose improved kink protection is reduced.
  • the invention is characterized in that the Shut-off valve device in one axis with the inlet duct is arranged for the introduced high pressure medium, where the outlet channel, downstream of the shut-off valve device, in continues at an angle to the axis of the inlet duct.
  • the shut-off valve device and the high-pressure hose connected to it coaxially are arranged at approximately the same height as the actuating lever in front of it.
  • This has the advantage that the pivot point of the pivot bearing of the actuating lever can be placed in the upper, outer and front end of the housing of the manual shut-off gun, in order to achieve the largest possible actuation path for the actuating lever.
  • the operating lever has a relatively long handle, which is far from
  • Pivot point is removed. This can make a big one Actuation path can be worked with low force.
  • the hereby achieved transmission ratio leads to a very low pull-off force (approx. 4 Kp) and a low holding force of approx. 2 Kp.
  • the high-pressure hose is therefore inserted into the housing shell at approximately the same height and parallel to the actuating lever and connected to the inlet channel, which results in particularly short connection paths between the high-pressure hose and the shut-off valve device.
  • the wearing parts namely the valve element, such as valve seat, valve ball, actuating bolt and the like, can be easily accessed and replaced by unscrewing the HP hose without having to disassemble the gun.
  • this manual shut-off gun in hot water cleaning devices there is the further advantage that when the hot water is introduced, beyond the actuating lever and beyond the handle, the entire housing shell does not heat up very much in the area of the handle.
  • the actuating lever is designed as a two-armed lever, the handle being relatively long and the power lever relatively short are trained.
  • the power lever preferably has one Metal insert that acts on the valve tappet, thereby can be moved axially. So the valve tappet can can be moved with great force.
  • a cross-section through a is schematized in the figure Manual shut-off pistol shown after the innovation.
  • the manual shut-off gun essentially consists of two similar housing shells 5 together, in Figure 1, For a better overview, only one of the housing shells 5 is shown.
  • the two housing shells 5 define an in closed housing, which consists essentially of a Rear wall 7, from a front wall 6, from a bottom wall 8 and consists of an end wall 9.
  • An anti-kink sleeve 2 is arranged outside the housing, which is part of an anti-kink device, by means of which the high-pressure hose 4 is protected against kinking to the manual shut-off gun to be led.
  • the kink protection sleeve 2 and the high pressure hose 4 are renewed approximately at the level of the operating lever 15 and arranged in front of this.
  • This kink protection device consists in essentially from a lower, tulip-shaped outward opening receiving opening 3, into which the high pressure hose 4th is introduced by means of a press sleeve 20 on a Approach of a press nipple 18 is kept sealing.
  • a fastening nut 19 is fixed in the anti-kink sleeve 2 arranged that secured against rotation with an associated pin is held locked in the kink protection sleeve 2.
  • the press-in nipple 18 with corresponding Sealing means 39, 40 on the one hand on the fastening nut 19 and, on the other hand, sealingly engages the valve body 36 and but at the same time is rotatable to the parts mentioned, so that the high pressure hose 4 rotatable and sealed in the Manual shut-off gun 1 is held.
  • An inlet channel 41 provided in the press-in nipple 18 for the High-pressure medium opens into a socket 17 via a shoulder, which as a separate nut part in the valve body 36 is screwed in.
  • This socket 17 forms the lower part of the Shut-off valve device 10.
  • the socket 17 takes one Compression spring 16, the other end of which is on a valve ball 11 supports, which in turn is held in a valve seat 12 becomes.
  • a valve tappet 13 presses on the valve ball 11 is guided sealed in a bore of the valve body 36 and its upper free end through a guide bush 14 is performed, which is a corresponding for sealing Has stuffing box and O-rings. That way avoided that the high pressure medium from this guide channel of the Valve tappet 13 penetrates to the outside.
  • the operating lever 15 of the Handabschaltpistole 1 consists of two parts, one of which Part is relatively long and is designed as a handle 38, and the other part is relatively short and the above Power lever 37 forms.
  • This two-armed operating lever 15 is pivotally mounted in a pivot bearing 33.
  • the operating lever includes a return spring which moves the lever 15 in maintains its rest position (valve closed).
  • the power lever 37 acts with its Metal insert on the upper end of the valve lifter 13, which thereby being displaced in the axial direction and the valve ball 11 stands out from its valve seat 12. This will make the High pressure channel released and the high pressure medium flows from the interior of the high pressure hose via the inlet duct 41 and the now open valve seat 12 into the outlet channel 30, that is, downstream of the total number 10 Switch-off device.
  • the pressure quantity regulation 21 Downstream of this shutdown device 10 is the pressure quantity regulation 21 arranged, which consists essentially of a valve stem 22 which is in a valve body bore 34 is arranged rotatably.
  • the valve body bore 34 penetrates the high-pressure channel in the transverse direction and - advantageously for better operation - is the longitudinal axis of the Valve stem 22 approximately perpendicular to the axis of the outlet chamber 31 arranged, in which the high pressure spray tube is arranged. In this way it is ensured that the Operating device for pressure and volume regulation 21 is arranged approximately perpendicular to the axis of the spray tube in order to achieve good activity.
  • the actuating device of the pressure and quantity regulation 21 consists of a rotary knob 26, which rotatably with a Fastening screw 23 is connected, which in turn is rotatably connected to the valve stem 22. It is one inside cover cap 25 is provided, which compared to the rotatable knob 26 is fixed and are arranged on the corresponding setting symbols can, with an assigned setting mark on the rotary knob 26 cooperate. Otherwise, the rotary knob 26 is on one Adjustment ring 24 rotatably mounted and secured against lifting.
  • valve stem 22 is in the upper part of the valve body 36 sealed by means of a stuffing box 27 and has beyond Stuffing box an annular collar 35 of larger radial diameter on, which serves as a stop for the stuffing box 27 and at the same time as an axial displacement protection of the Valve stem 22 is used.
  • a first O-ring 28 arranged, which seals the high pressure channel 30 upwards, and a second O-ring 28 ', the high pressure channel down seals off.
  • the valve stem is now in the area of the High-pressure channel 30 penetrated by a through hole 29, that works like a valve plug. Depending on the rotation of the Valve stem 22 is thus the passage through the outlet channel 30 more or less opened in the outlet chamber 31.
