Patent ID: 7611345

Claim:
A structure for preventing axial leakage in scroll compressor comprising: a housing, comprising a flow inlet and a flow outlet; a frame, fixed in the housing; a compartment, disposed in the housing and separated into a high-pressure compartment, a low-pressure compartment, and a middle-pressure compartment between the high-pressure compartment and the low-pressure compartment; a separator, disposed between the high-pressure compartment and a low-pressure compartment, comprising an outlet at the center of the separator and at least a passage; a pair of scrolls, comprising a fixed scroll and a orbiting scroll engaged with the fixed scroll between the separator and the frame; a slider, movably disposed at the center at the top of the fixed scroll; a first compartment and a second compartment disposed between the fixed scroll and the slider, the first compartment communicating with the middle-pressure compartment through a channel formed in the fixed scroll; at least a pressure-regulating mechanism, disposed above the passage of the separator; and a guiding element, disposed in the slider, comprising an air passage connected to the passage of the separator; wherein the pressure in the high-pressure compartment is less than that in the middle-pressure compartment, the pressure-regulating mechanism opens to exhaust air from the middle-pressure compartment to the high-pressure compartment.
