Abstract

A main body for a spray gun, in particular a paint spray gun, has at least one head region for attachment of a nozzle arrangement. The head region has at least one inner wall, one outer wall and one middle wall arranged therebetween. The walls are formed in encircling fashion and in one piece with the main body, with the front end of the middle wall set back in relation to the front end of the outer wall along an axis. This main body does not require any additional sealing element for sealing between the atomization air region and horn air region. The middle wall is well protected against damage even when a nozzle has been unscrewed, and the gun head can be of very compact design.
