Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/174751
Kind Code:
A1
Abstract:
A compressor (1) comprises: a cylinder (11); a rolling piston (15) that rotates eccentrically along an inner peripheral surface (11a) of the cylinder (11); a vane (17) that is in contact with the outer peripheral surface of the rolling piston (15) and that partitions the space inside the cylinder (11) into a suction chamber and a compression chamber; and a vane spring (19) that impels the vane (17) towards the rolling piston (15) side. A spring insertion hole (18) into which the vane spring (19) is inserted is formed in the cylinder (11), the spring insertion hole (18) has a hole shape such that the height dimension H11 in the axial direction of the cylinder (11) is less than the width dimension W11 in the tangential direction of the cylinder (11), the vane spring (19) is a coil spring, and the vane spring (19) has a spiral shape such that the height dimension H21 in the axial direction of the cylinder (11) is less than the width dimension W21 in the tangential direction of the cylinder (11).
