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