Patent ID: 7547195

Claim:
A scroll compressor comprising: a sealed housing shell; an electric motor received within said sealed housing shell, said electric motor driving a shaft, said shaft causing an orbiting scroll member to orbit, said orbiting scroll member having a spiral wrap interfitting with a spiral wrap on a non-orbiting scroll member to define compression chambers to compress an entrapped refrigerant, said non-orbiting scroll member being received said housing shell in a sealed manner, and defines a suction pressure chamber on one side of said non-orbiting scroll and a discharge pressure chamber on an opposed side, with said orbiting scroll and said motor received within said suction pressure chamber, a check valve upstream of said discharge pressure chamber, and said check valve being downstream of said compression chambers; and an oil bleed valve for selectively opening a passage through said non-orbiting scroll and communicating said discharge pressure chamber to said suction pressure chamber, said oil bleed valve including a component which moves between an open and closed position when a temperature passes a predetermined limit, and said passage allowing hot oil to move downwardly onto a safety switch for said electric motor to stop operation of said electric motor when said oil bleed valve is opened.
