ABSTRACT:
A low wear poppet valve in a high pressure reciprocating pump. Relative movement of the mating surfaces due to compressive distortion is eliminated. There is a valve seat having a flow passage and an upper mating surface, and a poppet element which sealingly abuts this. The flow passage is in communication with a low pressure zone, and the outer surfaces of the seat and element are in communication with a high pressure zone. The poppet element has a recess in its mating surface surrounded by a wall portion, and the low pressure zone is communicated from the flow passage into the interior of the recess. This enables the wall portion of the element to be displaced inwardly and outwardly in concert with the wall portion of the seat by the cyclic pressure differential which is generated between the zones by the operation of the pump. This eliminates relative movement between these parts which would otherwise cause fretting wear of their mating surfaces.
