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.
Claims8
A spray gun (1) for spraying paints and viscous media that can be propelled pneumatically or electrically, the spray gun comprising:
- a housing (2) for accommodating a propulsion mechanism and components that effect mixture and metering;
- a handle (3) projecting from said gun housing (2);
- and
- a reservoir tank (4) removably attached to said gun housing (2) for holding a medium to be processed;
- a union nut (10) placed on said gun housing (2);
- and
- an extension pipe and an air cap (11) surrounded by said union nut (10) provided with mutually offset outlet openings (14,15) for compressed air by means of which various spray jets (I, II, III) are formed and with an atomiser nozzle (5) held in an oriented position and opened by means of a nozzle needle (16);
- wherein a selected one of said union nut (10) and a holding element (31) is connected with said air cap (11, 32) circumferentially;
- and
- wherein the holding element (31) is lockable in angular positions corresponding to the spray jets (I, II, III) and is disposed in an oriented position in relation to said gun housing (2);
- and
- wherein a selected one of the gun housing (2), and the holding element (31) is provided with two diametrically opposed control cams (35, 35′, 35″, 35′″) that are open at one end and run in a circumferential direction, and the holding element (31) is provided with guide elements (36, 36′, 36″, 36′″) that engage in the control cams (35, 35′, 35″, 35′″).
