Abstract
A scroll compressor having a fixed scroll member and an orbiting scroll member. The fixed scroll member has an end plate and a wrap attached to the end plate in an involute curve and, similarly, the orbiting scroll member has an end plate and a wrap attached to the end plate thereof in a juxtaposed relation with the fixed scroll member so that the wraps of the two scroll members are fitted closely together. A check valve is provided so that an exhaust opening of the end plate is always opened when the compressor is in its operation and closed only when the operation is stopped.
