Abstract
A rotary compressor is disclosed which is equipped with a bypass hole for bypassing a fluid under compression to the intake side and the capacity thereof is controlled through opening and closing of the bypass hole with a piston which is operated via a control valve, whereby the bypass hole is opened at or in the vicinity of a discharge port of the compressor and the capacity of the compressor is made to be controllable in the range of one hundred to substantially zero percent. By the application of such a rotary compressor to the compressor for an air conditioner, capacity control in the range of about zero to 100% of discharge quantity can be accomplished so that it becomes possible to obtain cooling capability which is in response to the heat load.
