Abstract: Devices deliver the content of an aerosol, and are used in powder-actuated tools. A spray nozzle includes a cylindrical housing having, at a first end, with a base having a mounting bore that extends inside said housing so as to receive a barrel of a powder-actuated tool. The nozzle is equipped with a securing means. The base includes lobes that lie opposite one another in a single plane. A peripheral section of the second end of the housing is located on the same side as one of these lobes and has a curved projection with a rounded outer surface and an upward taper to form a common top surface with an additional cylindrical projection partially embedded into the inner surface of the curved projection. A V-shaped groove in communication with an axial opening of the second end of the housing extends on a free side of the additional projection.

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.
