Title:
VARIABLE CAPACITY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2011/078547
Kind Code:
A2
Abstract:
The present invention relates to a variable capacity compressor. The variable capacity compressor, comprises: an intake seal, a crank seal and a discharge seal; a discharge outlet connected to said discharge seal and mounted to a discharge passage; and a check valve which opens and closes the discharge passage based on the pressure differentials in the intake seal, crank seal and discharge seal. Accordingly, the differential, between the check valve inlet and outlet pressures and the discharge pressure at the exit, are minimized by allowing the pressures of intake and crank seals to act upon the far-side of the valve body such that the pressure in the direction opposite to the discharge seal, is reduced.
