Abstract
A valve assembly especially adapted for use with very high pressure reciprocating pumps. The main components are coaxially aligned. A main high pressure passage extends through the center of the assembly and has check valves at opposite ends thereof. One of the check valves has an annular valve element comprising inner and outer sleeves which fit against one another with an interference fit. This annular valve element seats against a matching annular inlet passage.
