    Abstract: Spraying heads may be used in spray guns for applying a pressurized aerosol material in the form of jets or spray. A spraying nozzle for spraying a polyurethane material includes a cylindrical body provided, on a first end, with a base having a mounting aperture extending into the cylindrical body, forming a cavity for arranging a head of a gun. The base of the nozzle is in the form of oppositely-disposed leaves. A second end of the body is provided with a cylindrical shoulder, a through-bore of which is communicated with a V-shaped and laterally non-closed recess at the region of an outlet of the sprayed material. Oppositely arranged plate-like protrusions adjoin a lateral surfaces of the cylindrical shoulder. A mounting aperture end which adjoins the base has a circumferential cut. The spraying nozzle is provided with an attachment means used when in an inoperative position.

    Abstract: An electrostatic spray system includes an electrostatic tool, a spray tip assembly configured to receive a coating material, and an airflow to atomize and charge the coating material, and spray the coating material in an airflow direction. The spray tip assembly includes a first air cap horn having a recess in a first distal surface, a first charging pin disposed within the recess, and a grounded pin coupled to the spray tip assembly. The first charging pin and the grounded pin are configured to produce an electric field that charges the coating material.

    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.
