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