容量可変型ロータリ圧縮機及びその運転方法

Document Type and Number:

Japanese Patent JP4516123

Kind Code:

B2

Abstract:

A capacity variable type rotary compressor and a driving method thereof are provided. The compressor includes bypass holes that connect a compression chamber and a suction chamber of a cylinder divided from each other by a vane formed at a sub bearing, a sliding valve that opens and closes bypass holes installed at the sub bearing, and a pressure difference maintaining device that enables the sliding valve to perform a capacity exclusion driving, thereby lowering a cooling capability at the time of the capacity exclusion driving. By maintaining the capacity exclusion driving for a long time, an air conditioner is variously controlled and unnecessary power waste of the compressor and the air conditioner to which the compressor is applied is decreased. A back pressure of the sliding valve is fast and precisely switched by a pilot valve having a high reliability, so that the compressor is widely applied to an air conditioner thereby to enhance the efficiency thereof.
