Claim:
A scroll compressor comprising: an orbiting scroll member having an orbiting end plate and an orbiting spiral wrap extending from said orbiting end plate; a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from said non-orbiting end plate, said non-orbiting spiral wrap being intermeshed with said orbiting spiral wrap to create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone; a drive member for causing said orbiting scroll member to orbit relative to said non-orbiting scroll member to compress a fluid within said pockets; a discharge slot formed by one of said orbiting scroll member and said non-orbiting scroll member; and a discharge valve rotatable with said drive member and operable between a closed state preventing fluid communication between said pockets and said discharge slot and an open state permitting fluid communication between said pockets and said discharge slot.
