Abstract: A spray gun is provided with a handle part (6) and a housing (2) having a connecting part (3) for a pressure can, said connecting part being provided with a check valve. The housing (2) receives a nozzle pipe (10) bearing a nozzle (11) at the free end, into which pipe a spring-loaded nozzle needle (12) acting upon the opening of the nozzle (11) extends. The nozzle needle is operable via a pivoted lever (9) mounted in the housing (2). To permit the position of the pressure can to be varied and fixed relative to the handle part (6) while involving a simple structure, the housing part (17) bearing the connecting part (3) for the pressure can is adapted to be rotated around the axis (19) of the nozzle needle (12) relative to the housing part (18) bearing the handle part (6).
