Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/135656
Kind Code:
A1
Abstract:
The present disclosure may provide a compressor in which an outer circumferential side cross-sectional area of a vane slot is formed to be smaller than an inner circumferential side cross-sectional area thereof to decrease an area receiving a force in a roller direction by a vane so as to reduce a contact force between the roller and the vane, and a gas accommodation portion capable of selectively forming a suction pressure and an intermediate pressure is formed between the vane and the vane slot to appropriately control a contact force between the vane and the roller, and a contact surface of the vane facing the roller is broadly formed at a side of a compression chamber to appropriately reduce a contact force between the roller and the vane, and a space portion forming a discharge pressure is formed at least either one side of a side surface of the vane and a cylinder corresponding thereto to decrease a side directional reaction force applied to the vane, thereby reducing a mechanical friction loss between the vane and the cylinder.
