ABSTRACT:
An improved shaft sealing ring for a portable paint gun of the type having an axially movable control shaft for controlling a supply of pressurized air to atomize a stream of paint. The sealing ring has a truncated frustro-conical surface tapering from a radially extending retaining surface toward a front end of the sealing ring and a radially extending flange at a back end of the sealing ring with an outer peripheral groove in an outer surface of the ring body between the flange and the retaining surface. The ring is installed by urging the front face through an opening having a diameter smaller than that of the face, the opening defined by a wall extending radially inwardly as a part of the gun housing. The flange is resiliently deflected to form a seal when the ring is installed. A central bore of the seal is sized to receive the shaft with a seal between the shaft and the ring provided by a ridge extending radially into the bore of the ring at the back end thereof. The ridge is urged against the shaft by deflection of the flange, thus improving the seal between the ring and the shaft.
