Rotary compressor with a vane discharge-sided groove and a vane suction-sided groove
Abstract:
A rotary compressor includes a cylinder having a vane slot and a compression chamber, a shaft having an eccentric portion and configured to perpendicularly pass through a center of the compression chamber, a roller having a coupling groove and configured to orbit in the compression chamber by rotation of the shaft, and a vane having a vane hinge coupled to the coupling groove and a vane body being inserted into the vane slot and configured to divide the compression chamber into a discharge space and a suction space. A shape of the discharge-sided groove close to the discharge space and a shape of the suction-sided groove close to the suction space are asymmetrically formed between the vane hinge and the vane body with respect to the a central axis of the vane.
