Variable capacity rotary compressor

A variable capacity rotary compressor comprising:

• a housing having first and second compression chambers partitioned each other;
• first and second vanes moving backwards and forwards in radial directions of the first and second compression chambers and partitioning the first and second compression chambers;
• first and second vane guide slots formed in the housing in order to guide operation of the first and second vanes;
• and
• a vane controller controlling the operation of the first vane in order to vary compression capacity,
• wherein the vane controller includes a control valve that switches a fluid channel so as to selectively apply discharge pressure and intake pressure to the first vane guide-slot, a connection channel that connects the control valve with the first 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 first vane guide slot.
