WIPO Patent Application WO/2023/012852

Kind Code:

A1

Abstract:

This hermetic compressor is provided with a hermetic container constituting an outer hull and a compression mechanism part accommodated in the hermetic container. The compression mechanism part is provided with a hollow cylindrical cylinder having a vane groove provided in a radial direction, a rolling piston eccentrically rotating along an inner peripheral surface of the cylinder, a partitioning vane reciprocating inside the vane groove and partitioning a space between the inner peripheral surface of the cylinder and the rolling piston into a high-pressure side and a low-pressure side, and a vane spring urging the vane to be brought into contact with the rolling piston. A load center position due to the vane spring gets closer to the low-pressure side than a center position of the vane.
