Abstract
A compressor is provided which minimizes impact noise and abrasion between a Z-plate of the compressor and vanes formed in the compressor. Ends of the vanes formed in the compressor contact sides of the Z-plate, and the motion and surface configuration of the Z-plate cause the vanes to move reciprocally and to section compression spaces within the compressor into a suction area and a compression area. Due to the curvature of the surfaces of the Z-plate, the vanes remain in constant contact with the surface of the Z-plate, which allows for smooth transition phases and a subsequent reduction in impact noise and abrasion between the vanes and the Z-plate.
