Title:
COMPRESSOR AND REFRIGERATION CYCLE DEVICE WITH SAID COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/152799
Kind Code:
A1
Abstract:
This compressor is provided with a closed container, an electric motor unit, a crankshaft, and a compression mechanism unit. The crankshaft has an eccentric shaft part. The compression mechanism unit comprises: a cylinder having a cylinder chamber into which a refrigerant is suctioned and compressed; a rolling piston that is fitted with the eccentric shaft part and is accommodated in the cylinder chamber, and that rotates with the eccentric shaft part to compress the refrigerant; and a vane that is provided in a vane groove formed in a radial direction of the cylinder and that follows the rolling piston to thereby partition the cylinder chamber into a suction chamber and a compression chamber for the refrigerant. The vane groove does not penetrate through to the outer peripheral surface of the cylinder on one end surface side of the cylinder. A vane stop part is formed at an end on the outer peripheral surface side of the cylinder. On the other end surface side of the cylinder, the vane groove is formed to penetrate through the outer peripheral surface of the cylinder. The vane is so configured that the length of a portion thereof positioned on the other end surface side of the cylinder on which the outer peripheral surface is penetrated through is longer than the length of a portion thereof positioned on the one end surface side of the cylinder at which the vane stop part is formed.
