Definitions
- the present invention involves a manual shut-off gun Anti twist device for a high pressure hose.
- EP 0 421 194 A2, US go from the prior art 4,709,859 A and DE 396 12 977 U, the shut-off pistols for Show high pressure cleaner.
- DE 396 12 977 U shows a hand-held spray gun for a high-pressure cleaning device in which a pipe and other anti-rotation means Anti-rotation is shown inside the housing.
- the US 4,709,859 A shows a high pressure washing device with spray gun, which also already shows an anti-rotation device arranged in a housing.
- EP 0 421 194 A2 (cf. preamble of claim 1) now includes a spray gun for this purpose High-pressure cleaning device with an anti-twist device that indicates the Arrange anti-twist device in the housing of the manual shut-off gun.
- the problem of friction between is not solved the high pressure hose and the necessary kink protection. Because of the constant twist the high pressure hose inside the tight around the high pressure hose arranged kink protection creates a permanent friction between them both components, which in the long run causes corresponding damage occur, which on the one hand represent undesirable wear effects and on the other hand can also endanger the operating personnel.
- the present invention is therefore based on the object, one in the housing an anti-twist device integrated in a spray gun for high-pressure cleaning devices for the high pressure hose so that they are essential during operation is more reliable than the current state of technology shows.
- the anti-twist device is arranged in the housing is. It is preferably integrated in the valve body.
- the kink protection sleeve which is usually on such Manual shut-off guns are provided, themselves part of the anti-twist device.
- the anti-twist device is not in the housing shells of the manual shut-off gun is arranged, but separately of which in the kink protection sleeve, but part of the housing of the manual shut-off gun is, but is arranged outside the housing shells.
- Another advantage of the invention is that it is standard High pressure hoses can be used in an associated Press sleeve are taken, the anti-twisting device in the valve body itself is integrated.
- valve device is then immediately above the twisting device (press-in nipple) the manual shut-off gun arranged what with a particularly crowded Space structure and the use of fewer construction parts.
- twisting device press-in nipple
- anti-twisting devices inexpensively with few means can be integrated directly into the valve body of the manual shut-off gun.
- the press-in nipple has a slight axial play in the receiving bore of the valve housing to allow easy rotation of the parts mentioned guarantee. It is preferred if at the lower end of the Press-in nipple a mechanical ring made of a plastic material, in particular Teflon, which is the friction between the press-in nipple and the associated mounting nut reduced.
- the figure shows a cross section through a manual shut-off gun shown according to the invention.
- the manual shut-off gun essentially consists of two mirror-symmetrical housing shells 5 arranged with respect to one another, only the one housing shell 5 is shown, while the other housing shell is accurate is the same.
- the two housing shells 5 define one in itself closed housing, which consists essentially of a rear wall 7, from a Front wall 6, consists of a bottom wall 8 and an end wall 9.
- a kink protection sleeve 2 is arranged, which Kink protection device has.
- This kink protection device consists in essentially from a lower, tulip-shaped opening to the outside Receiving opening 3, into which the HD hose 4 is inserted, which by means of a Press sleeve 20 is held sealingly on a neck of a press-in nipple 18.
- a mounting nut 19 is fixed, the with an associated pin 40 locked against rotation in the kink protection sleeve is.
- the advantage here is that the press-in nipple 18 with appropriate Sealants on the one hand on the fastening nut 19 and on the other the valve body 36 seals and at the same time to the parts mentioned is rotatable, so that the high pressure hose 4 is rotatable in the Manual shut-off gun 1 is held. Between the press-in nipple 18 and the Fastening nut 1ß a sliding ring 39 is used.
- the press-in nipple 18 opens via a shoulder into a bushing 17, which as separate nut part is screwed into the valve body 36.
- This socket 17th forms the lower part of the valve assembly because the bushing has a compression spring 16 records, the other end of which is supported on a valve ball 11, which in turn in a valve seat 12 is held.
- a valve lifter 13 presses on the ball is sealingly guided in the valve body 36 in a bore and its upper free End is guided by a guide bush 14 which has a corresponding Gland and O-rings. In this way it is avoided that the High pressure medium from this guide channel of the valve lifter 13 to the outside penetrates.
- the Actuating lever 15 of the manual shut-off gun 1 consists of one two-part lever, the one lever is relatively long and as Hand rest 38 is executed.
- This operating lever as a two-armed lever is in the pivot bearing is pivotally mounted, and the other lever part is from the previously mentioned power lever 37 formed.
- This power lever 37 thus works with his Metal insert on the upper end of the valve lifter 13, which is thus in the axial Is displaceable in the direction and thus the valve ball 11 from its valve seat 12 takes off. This releases the high pressure channel and the high pressure medium flows from the interior of the HP hose over the now open valve seat 12 in the HD channel 30 downstream, the total designated 10 Shutoff.
- the Connection between the fastening nut 19 and the anti-kink sleeve 2 released that can be easily removed afterwards, and after that the Seal 41 in the press-in nipple 18 can be easily replaced. Furthermore, the Anti-kink sleeve 2 a toothing 42 at its upper end, which as Helical internal toothing is formed. This toothing 42 engages Slider 43, which has an operating button 44, which is fixed to a Sliding part 45 is connected, which sliding part has a latch 46, which in Engagement with the toothing 42 can be brought.
- the slider 43 is spring-loaded in a recess 48 in by means of a spring 47 the housing shell 5 of the manual shut-off gun 1, so that the Actuating button 44 is held spring-loaded in its downward position becomes. It is in the area of a recess 49 in the space between the housing shells 5 slidably held.
- the sliding part 45 is in the shift position shown in the figure with its locking lug 46 in engagement with the toothing 42 so that the Anti-kink sleeve 2 rotatably with the housing shells 5 of the manual shut-off gun 1 is coupled.
- rotation lock is important in the event that a user unintentionally twisted the entire arrangement, with the risk that the High pressure hose from a screw connection on the manual shut-off gun is turned out. If this high pressure hose is then under High pressure medium, it can cause serious damage and injuries to lead. This is avoided by said rotation lock, which is only arbitrary can be triggered by actuating an actuating button 44.
