Abstract:
1. A rotary compressor, comprising: a cylinder internally formed with a compression chamber; a rotating shaft penetrating a central area of the compression chamber; a roller eccentrically coupled to the rotating shaft, and eccentrically rotatable within the compression chamber by rotation of the rotating shaft to compress media; a vane contacting an outer surface of the roller to partition the compression chamber and reciprocating in a radial direction of the compression chamber as the roller eccentrically rotates; a vane slot comprising, a vane guide part formed on a wall of the compression chamber to accommodate and guide the vane to reciprocate, and an extension width part formed an outer end part of the vane guide part and larger than a width of the vane guide part by a predetermined extension width; the extension width part is in selective fluid communication with either the discharge pipe or a low pressure pipe in order to move the vane into either engagement or disengagement with the roller; and a capacity reduced part inserted in the extension width of the extension width part with a predetermined space apart from the vane guide part and reducing capacity of the extension width part to decrease the actuating time of the vane.
