A spray gun including a nozzle portion in which a substantially V-shaped groove is formed in a circular section of a truncated conical front end with a cone angle ranging from 20° to 90°, and an internal hole is opened as a liquid ejecting port by forming the substantially V-shaped groove; and a gas cap including a cap face which is provided with an atomized gas opening portion having an opening diameter larger than the circular section, the gas cap forming a circular slit-like gap between the gas cap and an outer periphery of the truncated conical front end, the gap being configured to eject gas for atomizing liquid. The circular section of the truncated conical front end has a diameter ranging from 0.8 mm to 2.8 mm. The atomized gas opening portion has the opening diameter equal to or larger than 1.0 mm and smaller than 3.0 mm.

An airstream propelled spray atomizer apparatus and method of fluid atomization by codirectional airstream propulsion enables controllable atomization of a second fluid into a first fluid for use in surface treatment and cleaning. A user is able to alter the amount of atomization of the second fluid, from a spray to a mist, during spray operations without having to stop and change nozzles. Further, effectuating atomization via in-stream introduction rather than via structural impediments disposed interior to the nozzle prolongs nozzle life over extended operations.

A kit for a spray gun including a sleeve delimiting an inner volume provided to contain a pressurized fluid, the sleeve being configured to be connected to a main body of a spray gun, the sleeve having a radial periphery delimiting a fluid outlet of the sleeve and at least one orifice emerging on the radial periphery and fluidly connecting the inner volume and the radial periphery, a connector having an intake end connected to the fluid outlet and a connecting end suitable for being connected to a cup so as to fluidly connect the cup to the inner volume of the sleeve, and a ring surrounding the sleeve and covering the fluid outlet outside the intake end of the connector.

A manually-operated paint spray gun includes a body having a nozzle for atomizing paint to be sprayed and a handle forming a handgrip and provided with a connector for the inflow of compressed air to be supplied to the nozzle, wherein the handle of the gun has a compressed air regulator operatively associated to which is a pressure sensor at least part of which is arranged in a removable portion of the handle forming a substantial part of the dorsal area of the handgrip and is separated from the inflow connector.

A connector unit (23) for a spray gun (10) for spraying a flowable material using compressed air includes a first connector (28) for the connection of an air line (29) and a second connector (30) for the connection of a material line (31), the connector unit being configured as a swivel joint (25) in such a manner that the first connector and the second connector are rotatable around a shared rotation axis (32) relative to the spray gun.

A spray gun is configured to emit spray fluid and compressed air that impinges on the spray fluid to atomize the spray fluid. A trigger actuates one or more valves of the spray gun to cause spraying by the spray gun. The trigger is mounted to a gun body of the spray gun by a trigger mount. The trigger is removable from the gun body and includes one or more tool interfaces for connecting and/or disconnecting components of the spray gun.
