PURPOSE: Pressure controlling structure of an asymmetric scroll compressor is provided to minimize pressure unbalance between both sides compressor chamber formed by a wrap of a fixing scroll and a wrap of a turning scroll, and to prevent generation of a reverse rotation torque. CONSTITUTION: A compressor unit is composed of a fixing scroll(30) fixed on a frame(1) and a turning scroll(40) rotated between the fixing scroll and the frame. The fixing scroll forms a wrap(31) of an involute shape on inside of a body(32) having a discharge hole(33) in the middle of the body. The turning scroll forms a wrap(41) corresponding to the involute curved shape of the fixing scroll wrap on a side of an end plate unit(42) having a specific thickness and area. A boss unit(43) is connected to an eccentricity unit(2a) of a rotation shaft on the other side of the end plate. Pressure controlling structure of an asymmetric scroll compressor pressurizes refrigerant gas by balancing pressure between compressing chambers formed by the fixing scroll wrap and the turning scroll wrap. Moreover, the pressures controlling structure prevents noise, vibration and wear through behavior by preventing generation of counter force of an Oldham ring and the counter rotation torque of the turning scroll.
