FIELD: devices for liquid atomisation or spraying.
SUBSTANCE: invention relates to a spray gun for a high pressure cleaning apparatus. Spray gun (10) for a high-pressure cleaning appliance comprises gun casing (12), in which there is arranged valve (26), having through duct (34) which extends from valve inlet (30) to valve outlet (32). Spray gun also comprises closure body (36) which, in a closed position, bears in a fluid-tight manner against valve seat (56) and which can be moved to an open position away from valve seat (56) with the aid of hand lever (48) mechanically coupled to closure body (36). Spray gun also comprises electric apparatus (100) which has electric display device (140) and at least one battery (114). Electric apparatus (100) has electric casing (102) which is sealed against sprayed water and forms a sub-unit which can be handled independently. All of the current-carrying components of spray gun (10) arranged in electric casing (102) and are separated galvanically from the remaining components of spray gun (10). Spray gun comprises device (162) for detecting downstream of valve seat (56) in through duct (34) prevailing fluid pressure, outside of electric housing (102) in the pistol housing (12) is arranged sensor element (138) of electric device (100) coupled, arranged and wirelessly with inside of electrical enclosure (102).
EFFECT: cost optimisation in its manufacture and assembly, id est improving its manufacturability, as well as ensuring its protection from external disturbances and ease of maintenance.
