Abstract
A scroll-type compressor has a fixed scroll member, a movable scroll member, a front housing, a rear housing and a gasket seal. The fixed scroll member and the movable scroll member cooperate to form a compression region. The movable scroll member orbits relative to the fixed scroll member to compress refrigerant in the compression region. A movable scroll base plate of the movable scroll member forms a rear surface and a discharge hole substantially at the center of the movable scroll base plate. Pressure of the refrigerant discharged from the compression region is applied to the rear surface of the movable scroll base plate. The front housing accommodates the movable scroll member. The rear housing which is adjacent to the front housing, has the fixed scroll member inside. The gasket seal is located between the front housing and the rear housing.
