Title:
VARIABLE-DISPLACEMENT SWASH PLATE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/136694
Kind Code:
A1
Abstract:
The present invention provides a variable-displacement swash plate compressor which has an orifice member forming an orifice on a discharge passage connecting a discharge chamber and a discharge port, and measures a differential pressure with a difference between a refrigerant pressure in the front part of the orifice and a refrigerant pressure in the rear part of the orifice, on the basis of the orifice formed by the orifice member, so that driving torque can be predicted from the measured differential pressure, and the differential pressure can be adjusted by adjusting the diameter of the orifice by replacing the orifice member.
