Scroll-type compressors

Abstract

A scroll-type compressor includes a housing including a suction chamber and a discharge chamber. The compressor also includes a fixed scroll including a first spiral element, and an orbiting scroll including a second spiral element. Specifically, the orbiting scroll is positioned inside the suction chamber, and the first spiral element and the second spiral element interfit with each other to form a fluid pocket. Moreover, the compressor includes a driving mechanism for moving the orbiting scroll in an orbiting motion, a rotation prevention mechanism for preventing the orbiting scroll from rotating, and a communication path formed at a lower portion of the fixed scroll. Specifically, the communication path allows fluid communication between a lower portion of the discharge chamber and a lower portion of the suction chamber.
