Abstract (en)
[origin: EP1234616A2] The hand spray pistol has a fluid conduit in which is a closure valve openable by an operating component. In the fluid conduit (2) in the flow direction, two closure valves (9,10) are arranged one behind the other, which by means of the same operating component (6,7) are so openable one after the other, that with reduced operation of the component only one closure valve (9) is opened. Only by more forceful operation the second closure valve (10) is also opened, in the area of which a by-pass conduit is arranged which issues into the fluid conduit (2). The flow cross-section of the by-pass conduit is smaller than that of the fluid conduit.
