Rotating coating product projector e.g. electrostatic type water soluble liquid coating product projector, has pneumatic turbine, where flow volume of exhaust gas towards projector`s front is situated radially inside skirt air flow volume

摘要

The projector (1) has a pneumatic turbine (4) that drives a rotating spray bowl (8) in rotation, and air flux guiding pipes (7, 29) of the rotating bowl. Flow volume (V1) of the exhaust gas (F1) towards front (D) of the projector is situated radially inside a flow volume (V2) of skirt air (F2). A body (5) defines a housing to receive a turbine (4) and a hood mounted around the body. The body is mounted on a support (2) with a sealing joint (53) in a contact zone (51). The hood defines an outer surface (76) of the projector near the bowl.
