Rotary compressor

Abstract

A rotary compressor 100 includes a drive shaft 101 having an eccentric shaft 101a, a piston 102 fitted onto the eccentric shaft 101a, a cylinder 103 that receives the eccentrically rotating piston 102, an upper end plate 104 and a lower end plate 105 that close the upper and lower opening surfaces of the cylinder 103, a vane 106 that divides a space formed by the cylinder 103, the piston 102, the upper end plate 104, and the lower end plate 105 into a suction chamber 113 and a compression chamber 114, a discharge space 117 that is formed by causing the cover 108 to close a recessed portion 107 obtained by recessing a surface of either the upper end plate 104 or the lower end plate 105 on the opposite side to the cylinder 103 and where discharge gas flows in from the compression chamber 114 and directly flows out to the outside of the compressor 100, and spatial volume of the discharge space 117 having 10 times enclosed volume of the cylinder 103, thereby reducing noise and vibration due to discharge pulsation as well as improving efficiency and reliability and reducing cost.
