Abstract
An improved cartridge assembly (10) is used in a pump to bypass excess fluid flow and vent excess fluid pressure. The cartridge assembly includes a housing (24) which is located in and fixedly secured to a pump body (14). An orifice (62) is disposed within the housing (24) to establish a pressure differential in a flow of fluid from an inlet (34) to the housing to an outlet (42) from the housing. A fluid bypass port (38) is formed in the housing (24). A flow control valve (66) is disposed within the housing (24) and is movable relative to the housing to control the flow of fluid through the bypass port (38). A pressure relief valve assembly (104) is disposed in the housing (24) and is operable to an open condition to vent excess fluid pressure to the bypass port (38) through passages (106 and 107) formed in the flow control valve (66). The pressure relief valve assembly (104) is connected with the flow control valve (66) and moves with the flow control valve relative to the housing (24).
