More Information
Summary: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.
