  • Patent number: 4489752
    Abstract: A multi-element poppet valve for use with high pressure gas compressors wherein the over-hang of the poppet element head has been substantially eliminated to strengthen the poppet element. The stem of the poppet element is aerodynamically configured in an outer convex wall surface which flares smoothly outwardly from the bottom of the stem to the beginning of the head portion. The head portion has a bell-shaped top which flares outwardly in a concave surface to the edge of the poppet element. The poppet element is restrained for reciprocating movement by a guide insert fixed to the bottom of the guard bore cavity which telescopically receives the poppet element stem. Elimination of the over-hanging poppet head minimizes turbulence and reduces the possibility of breakage under high differential pressure conditions.
