Abstract

A nozzle arrangement for a spray gun, in particular a paint spray gun, has at least one paint nozzle and an air cap. The paint nozzle has at least one outlet opening for the material to be sprayed and the air cap has at least one central opening which is bounded by at least one wall. The at least one wall forms a gap with at least one part of the paint nozzle, and a forward part of the paint nozzle has at least an inner face, an outer face and an end face. The end face of the paint nozzle encloses, at least in certain regions, an angle of greater than 90° or an angle of less than 90° with an outer face or an inner face of the paint nozzle. In the nozzle arrangements, the back-pressure counter to the outflow of the material to be sprayed is lower than in prior art nozzles. A spray gun, in particular a paint spray gun, having such a nozzle arrangement is also disclosed.
