Abstract

In a spray gun (1) for spraying paint with a gun housing (2) provided with a handle (3) with a union nut (10) screwed onto it that holds an air cap (11) provided with offset outlet openings (14, 15) for compressed air, the union nut (10) is positively connected to the air cap (11) in a circumferential direction. This embodiment makes it possible for the spray jet to be set in a brief time and without difficulties without having to put up with getting dirty. It is merely necessary to turn the union nut (10) accordingly in order to control the air supply to the outlet openings (14, 15) of the air cap (11) and therefore to influence the formation of the spray jet.
