Zusammenfassung:An improved unloader valve assembly for a high-speed reciprocating compressor includes improved poppets and valve seat designs. The improved poppets and valve seats are useful for reducing or eliminating poppet leakage and high impact stresses on the sealing surfaces of the poppets, and are especially intended for use with high-speed reciprocating compressors operating at 1000 rpm and higher. A control chamber spacer plate for creating a control pressure chamber within the unloader valve assembly, and a valve seat cushioning plate for reducing stress on the head ends of the poppets are also described.
