This gun comprises a body (1) fitted with a spray nozzle (13) connected to a threaded connector (coupler) (15) via a passage (18) in which there is a valve (8, 9) controlled by a piston (24), which is mounted so as to slide in a chamber (23, 34) formed in the body and connected via a passage (33) to a threaded connector (29) for a compressed-air inlet hose (pipe) (31). The body (1) is assembled onto and fixed in a detachable manner to a support base (2). The body and the base have, in the assembled state, assembly surfaces (1a, 2a) which are pressed against each other; the threaded connectors (15 and 29) are carried by the base (2) and the passages (18 and 33) are formed in part (18a, 33a) in the body (1) and in part (18b, 33b) in the base (2); the respective parts of the passages are connected up in a sealed manner at the surfaces (1a, 2a). <IMAGE> |
