Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/169117
Kind Code:
A1
Abstract:
A rotary compressor according to the present embodiment comprises: a main bearing and a sub-bearing which are respectively provided on both sides of a cylinder in the axial direction and each provided with a guide groove; a roller which is accommodated in the cylinder and rotated along with a rotary shaft; at least one vane which is slidably inserted in the roller, and on which a guide protrusion that is slidably inserted in the guide groove in the circumferential direction is extended in the axial direction; and a bearing member which is provided between the guide groove of at least one bearing between the main bearing and the sub-bearing and the guide protrusion of the vane. As such, the frictional loss between the vane or the roller and the main bearing or the sub-bearing facing same can be reduced to improve the compressor efficiency.
