Abstract (en)
[origin: EP0429831A2] In a high-pressure cleaning device for discharging cleaning fluid which is made to foam by feeding in compressed air, a water shut-off valve (2) is arranged in the fluid feed line (3, 5) and an air shut-off valve (11) is arranged in the air feed line (12). The cleaning fluid mixed with compressed air is fed to a working hose (6) forming a foaming space and is discharged from the latter in a foamed state. A hose-shaped control line (20) which is fed with compressed air is connected by one end to a reverse valve (21) which, when a high pressure is present on the control line (20), feeds the shut-off valves (2, 11) with compressed air which closes them, and has at its other end adjacent to the outlet end of the working hose (6) a manually opening valve (23). The control line (20) runs partially inside the working hose (6). <IMAGE>
