ABSTRACT:
A scroll-type compressor has an orbital scroll member and a stationary scroll member each having a disc-shaped end plate and a spiral wrap protruding upright from the end plate. The scroll members are assembled together with their wraps meshing with each other to define compression chambers therebetween. The orbital scroll member executes an orbital movement without rotating around its own axis. A discharge port and a suction port are formed in a central portion and a peripheral portion of the end plate of the stationary scroll member, respectively. As the orbital scroll member makes the orbital movement, the compression chambers are moved towards the center while decreasing their volumes thereby to progressively compress a gas drawn through the suction port and to discharge the compressed gas through the discharge port. The compressor further has a check valve disposed in a gas passage which is formed through the thickness of the end plate of the stationary scroll member so as to communicate with a suction chamber formed between the scroll members.
