Embodiment Construction

[0056] specific implementation plan

[0057] figure 1 and figure 2 A first advantageous embodiment of the valve gun according to the invention is shown schematically and designated as a whole by the reference numeral 10 . The valve gun 10 comprises a gun housing 12 which is formed from a first half shell 14 and a second half shell 16 . The gun housing 12 has a longitudinal housing region 18 at the front side 20 of which a liquid outlet 22 is arranged. The liquid outlet 22 is designed in the form of an outlet bush 24 which has an external thread 26 . The injection nozzle is connected to the outlet bushing 24, for example.

[0058] Projecting from the longitudinal housing region 18 at a distance from the liquid outlet 22 is a handle 28 which can be gripped by the user's hand. The handle 28 has an upper end region 30 connected integrally with the longitudinal housing region 18 and assigned to the user's thumb and forefinger, and an upper end region 30 facing away from this ...

Abstract

The invention relates to a valve gun (10, 100, 120) for a high-pressure cleaning device, the valve gun having a gun housing (12), the gun housing having a handle (28), the handle comprising a thumb and a forefinger assigned to a user The upper end region (30) of the user and the lower end region (32) assigned to the user's little finger, and the valve gun has a liquid inlet (46) and a liquid outlet (22) arranged between the liquid inlet (46) and the liquid outlet (22) in the gun housing (12). A valve (38) in the fluid path, the valve has a closing body (66, 136), which in the closed position bears sealingly against the valve seat (60, 138) and can be passed through the valve tappet (62, 132) Moved into the open position, wherein the liquid outlet (22) is arranged on the front side (20) of the gun housing (12), and wherein the operating mechanism for moving the valve tappet (62, 132) ( 70, 22) are arranged on the rear side (78) of the handle (28) facing away from the liquid outlet (22). In order to further improve the valve gun (10, 100, 120) so that it has a simpler structural embodiment, it is proposed that the valve tappet (62, 132) can be operated in the lower end region (32) of the handle (28) ( 70, 122) loaded with manipulation force.

Description

technical field [0001] The invention relates to a valve lance of a high-pressure cleaning device, the valve lance for the controlled discharge of cleaning fluid, the valve lance having a lance housing, the lance housing having a handle, the handle including the upper end region assigned to the thumb and forefinger of the user And assigned to the lower end region of the little finger of the user, the valve gun has a valve arranged in the gun housing in the fluid path between the liquid inlet and the liquid outlet, the valve has a closing body, which is sealingly abutting in the closed position On the valve seat and can be moved into the open position by moving the valve tappet, wherein the liquid outlet is arranged on the front side of the gun housing, and wherein the actuating mechanism for moving the valve tappet is arranged away from the handle on the dorsal side of the liquid outlet. Background technique [0002] With the aid of such a valve lance, the discharge of the c...
