Abstract: An air cap for a spray gun, in particular a paint spray gun, having at least one central opening, which is delimited by a mouth, and two horns, each having at least one inner and one outer horn air duct and one inner and one outer horn air opening. The spacing between the front end of the central opening and an axis which perpendicularly intersects the central axis of the central opening and runs through the centre of an inner horn air opening is between 0.6 mm and 2.6 mm. The spray pattern generated by the air cap has a longer core region and a steeper transition of the layer thickness between the external region and the core region, compared to conventional air caps leading to improvement in coating quality. A nozzle assembly and a spray gun, in particular a paint spray gun, can have an air cap having the above properties.

Abstract: A portable breathing apparatus for protecting a user against contact with the contaminated surrounding atmosphere. The breathing apparatus can be supplied with fresh breathable air via an air tube connected to an air supply system having an overpressure. The breathable air flows out of a body which is connected to the air tube and has at least one defined outflow surface for the breathable air.

Abstract: The invention relates to a paint spray gun (1) having a compressed air distribution chamber (8) into which a compressed air feed line (10), a round jet line (6) and a wide jet line (7) open, the quantity of compressed air supplied to the compressed air distribution chamber (8), the round jet line (6) and the wide jet line (7) being adjustable via a setting element arranged in the compressed air distribution chamber (8) and rotatable from outside by an actuating element (15) about an axis of rotation (D) extending through the compressed air distribution chamber (8). Said paint spray gun (1) is characterized in that the setting element is formed as a rotary distributor (14) that is held immovably in the axial direction of the axis of rotation (D) and can be rotated about the axis of rotation (D) in order to open and close openings (6?, 7?, 10?) of the round jet line (6) and/or the wide jet line (7) and/or the compressed air feed line (10).

Abstract: A spray gun with a gun body having a handle region and having a head which is equipped with a cartridge which has an angled, tubular region as an inlet for a material-conducting channel which runs through the cartridge and ends in an outlet region which is arranged at the front end of the head of the spray gun, wherein the inlet region of the cartridge is connected or is connectable to a storage container for the material to be sprayed, and wherein the cartridge preferably guides at least one material-conducting component of the spray gun. The cartridge is held fixedly, but releasably, on the head of the spray gun by means of a screw collar ring, wherein the screw collar ring is preferably supported on the cartridge and/or on or in the head of the spray gun by at least one mechanism.

Abstract: An air nozzle closure for a spray gun with an air cap, which has at least one axial borehole for the passage of exiting air and a first annular flange, which is radially directed outward, and an air nozzle ring surrounding the air cap, with a second annular flange radially directed inward, and an inside thread for the screwing on of the air nozzle closure with an outside thread of the spray gun. The air cap in the screwed state, with annular flanges adjacent to one another, is clamped in between the spray gun and the air nozzle ring, and a first annular groove with a locking ring, which secures the air nozzle ring in the unscrewed state against the loosening of the air cap. The locking ring has at least one elastic snap-in element projecting inward to snap into the annular groove.
