Abstract

A compressor is provided in which a rotary member is suspended on a stationary member and rotates to compress a refrigerant. In the stationary member, top and bottom ends of a stationary shaft are fixed to improve structural stability and assembly properties. Bearing covers are provided on a contact portion of the stationary member and the rotary member, such that the rotary member may rotate when suspended on the stationary member, which stabilizes operation. In the rotary member, a vane is integrally formed with a roller and mounted on a vane mounting hole of a cylinder-type rotor. Although, the rotary member is provided on an outer circumferential surface of the stationary member, suction and discharge operations of the refrigerant are performed in an axial direction, which lowers product height. Oil stored in a hermetic container is supplied to a lubrication passage provided between the stationary member and the rotary member.
