Valve assembly for pressure washer pump

A pressure washer pump comprising:

• a pump housing that defines a longitudinally-extending cavity with an opening at one end thereof;
• a valve assembly disposed in the longitudinally-extending cavity such that a longitudinal axis of the valve assembly is coincident with a longitudinal axis of the longitudinally-extending cavity, the valve assembly comprising a first poppet valve, a second poppet valve, a connector member and an end member, wherein each of the first and second poppet valves comprises a cage, a valve spring, and a seal, wherein the cage comprises a plurality of axially spaced-apart hoop-shaped elements, a valve spring seat, and a plurality of longitudinally-extending members coupling adjacent ones of the hoop-shaped elements to one another, wherein the valve spring seat comprises a plurality of generally L-shaped tabs, each of the L-shaped tabs being integrally formed with an associated one of the longitudinally-extending members, wherein each of the longitudinally-extending members has a zone of reduced cross-sectional area that is configured to buckle when an axially directed force in excess of a predetermined crushing force is applied to the cage, the valve spring being received between the L-shaped tabs in the cage and the seal to bias the seal outwardly from the valve spring seat, the connector member having a connector body, a first coupling neck and a second coupling neck formed on opposite sides of the connector body, a first bore that is formed through the connector body, and a first seal seat, the cage of the first poppet valve being mounted about the first coupling neck, the seal of the first poppet valve being biased into sealing engagement with the first seal seat, the cage of the second poppet valve being mounted about the second coupling neck, the end member having a third coupling neck, a second bore and a second seal seat, the cage of the second poppet valve being mounted about the third coupling neck, and the seal of the second poppet valve being biased into sealing engagement with the second seal seat;
• a plug member coupled to the pump housing and closing the opening;
• and
• a compliant member disposed between the plug member and the cage of the first poppet valve.
