[origin: WO2017035289A1] A compressor (20) comprises: a case (22); and at least one piston (40) mounted for reciprocating movement, each in a respective cylinder (42) of the case. The at least one piston has a peripheral surface (50) and an upper surface (52). At least one discharge valve comprises: a valve element (150) shiftable between a closed condition and an open condition; a valve guide (170); one or more springs (180) held at least partially the valve guide biasing the valve element from the open condition toward the closed condition; and one or more vents (300) in the valve guide providing a flow path from a region above the valve element upward through the valve guide.
