ABSTRACT:
A scroll type compressor is disclosed. The scroll type compressor includes a housing, a frame, a compartment, a separator, a scroll pairs, a slider, a plurality of compartments, at least a pressure-regulating mechanism, and a guiding element. The compartment in the housing is separated into a high-pressure compartment, a low-pressure compartment, and a middle-pressure compartment. The separator is disposed between the high-pressure compartment and the low-pressure compartment. The separator includes an outlet at the center thereof, and at least a passage through the separator. When the pressure in the high-pressure compartment is less than that in low-pressure compartment, the pressure-regulating mechanism is opened to exhaust pressure from the middle-pressure compartment to the high-pressure compartment.
