Abstract

A co-rotating scroll compressor is provided in which pressure differences between inner and outer portions of a suction chamber are maintained, back pressures are applied to rear surfaces of end plates of a drive scroll and a driven scroll in directions in which the two scrolls are moved toward each other to prevent compression leakage of a fluid, and a lubricant oil is easily supplied to the two scrolls using the back pressures. The co-rotating scroll compressor may include pressure seals between the rear surfaces of the end plates of the drive scroll and the driven scroll and an inner wall of the suction chamber such that the two scrolls are pressed in directions to be moved toward each other by the back pressures, and the oil is supplied to rotary supports and close contact portions of the two scrolls using the back pressures.
