Abstract
A compressor assembly including a housing, a compression mechanism disposed in the housing and having a discharge port, and a discharge check valve assembly. Gas substantially at suction pressure is received into the compression mechanism, compressed and discharged substantially at discharge pressure from the compression mechanism through the discharge port. The discharge check valve assembly has at least one elongate guide pin extending from the compression mechanism and a valve plate disposed about the guide pin. The valve plate has a closed position at a first position along the guide pin in which the valve plate covers the discharge port and an open position at a second position different than the first position along the guide pin in which the valve plate does not cover the discharge port. Gas substantially at discharge pressure and having been discharged from the compression mechanism is substantially prevented by the valve, in its closed position, from reentering the discharge port.
