SWASH PLATE-TYPE VARIABLE DISPLACEMENT COMPRESSOR FOR SUPERCRITICAL REFRIGERATION CYCLE

Title:

SWASH PLATE-TYPE VARIABLE DISPLACEMENT COMPRESSOR FOR SUPERCRITICAL REFRIGERATION CYCLE

Document Type and Number:

WIPO Patent Application WO/2004/061306

Kind Code:

A1

Abstract:

A swash plate-type variable displacement compressor (10) used for a supercritical refrigeration cycle (1) has a rotatably installed swash plate (400), pistons (500) connected to the swash plate, and cylinders (600) movably retaining the pistons. The cylinders are provided with a suction valve (150) through which a refrigerant for the supercritical refrigeration cycle is sucked and a discharge valve (160) through which the refrigerant is discharged. The suction valve is constructed from a suction port (141) from which the refrigerant is sucked and a flexible valve body (152) mounted on the suction port. In order that the number of rotation of the swash plate is reduced at the time when the refrigerant starts to be compressed, the valve body is press-fitted in a valve seat of the suction port with the valve body elastically deformed.
