Abstract
A pressure relief assembly for use with a paint pump having a chamber with a pressure relief port located immediately adjacent an inlet port of the pump. The pressure relief assembly includes a mounting member, inlet washer, rupture pad and outlet washer. The mounting member is threaded on its exterior surface and includes an inlet end, an outlet end, and a relief passage extending between the inlet and outlet ends. A rupture recess in the inlet end is sized to receive the inlet washer, rupture pad and outlet washer, with the rupture pad positioned between the washers. The inner diameter surface of the outlet washer is convex. The pressure relief assembly is screwed into the pump with the inlet end adjacent to the pressure relief port. The rupture pad forms a seal between the pump chamber and atmosphere that ruptures to vent the chamber when the pressure within the chamber exceeds a predetermined rupture pressure.
