Abstract: A variable capacity rotary compressor is provided, in which a vane may be restricted by a pressure difference generated between both side surfaces of the vane when the compressor performs in a saving driving mode. The vane may be restricted quickly and stably by rapidly decreasing a pressure of a vane chamber by leaking a discharge pressure of the vane chamber to an inlet via a low pressure passage and thereby increasing a pressurizing force applied to a side surface of the vane relatively greater than a supporting force applied to a rear surface thereof. In this way, the vane may be prevented from being vibrated due to a weak restriction force of the vane when a power driving mode of the compressor is switched into the saving driving mode, which prevents noise from increasing due to design conditions, thereby enhancing a comfort feeling of a user.
