    摘要： A variable capacity rotary compressor capable of reducing collision noise of a vane with a roller. The variable capacity rotary compressor includes a vane controller controlling the operation of a vane in order to vary compression capacity. The vane controller includes a control valve that switches a fluid channel so as to selectively apply discharge pressure and intake pressure to the vane guide slot, a connection channel that connects the control valve with the vane guide slot, a high-pressure channel that connects the control valve with a discharge side of the compressor, and a low-pressure channel that connects the control valve with an intake side of the compressor, and a throttle section that reduces the fluid channel of at least one of the high-pressure channel and the connection channel in order to reduce an initial discharge pressure applied to the vane guide slot.

    摘要： A hermetic compressor for adjusting the length and cross sectional area of a communication path as a refrigerant flow passage, so as to attenuate a discharge pulsation and consequently, a vibration and noise thereof. The hermetic compressor, which includes a cylinder head having a discharge chamber to discharge a compressed refrigerant and a discharge muffler to receive the refrigerant discharged from the discharge chamber, further includes a communication path to communicate the discharge chamber and the discharge muffler with each other, so as to allow the refrigerant to flow from the discharge chamber into the discharge muffler, and an auxiliary communication tube to increase a length of the communication path for increasing a refrigerant flow distance. The auxiliary communication path reduces the cross sectional area of a refrigerant flow passage while increasing a refrigerant flow distance, thereby attenuating a low-frequency component of the discharge pulsation.

    摘要： An air conditioning system including a first compressor and a second compressor provided in parallel with the first compressor to vary compression capacity. The second compressor includes a housing having a compressing chamber, a vane that moves forward and backward in a radial direction of the compressing chamber, a vane guide groove formed in the housing to guide the forward and backward movements of the vane, and a vane controller that controls the operation of the vane in order to vary capacity. The vane controller includes a control valve that switches a fluid path so as to selectively apply suctioning pressure of the second compressor and discharge pressure of the first compressor to the vane guide groove and a controller that controls a fluid path switching operation of the control valve by a pulse width modulation (PWM) method in accordance with air conditioning load.
