Abstract
Provided is a variable-capacity compressor control valve that is compact and is capable of suppressing the influence of the pressure difference between the crank chamber pressure Pc, the suction pressure Ps, and the like. A valve body includes an in-valve release passage for releasing a pressure Pc in a crank chamber to a suction chamber of a compressor via a Ps inlet/outlet port. A sub valve element adapted to open or close the in-valve release passage along with movement of the plunger is provided.
