PROBLEM TO BE SOLVED: To stabilize control at a time of maximum capacity operation while ensuring oil circulation in a variable displacement compressor.SOLUTION: A control valve in one aspect is configured so that a valve element autonomously operates so as to keep a pressure difference between a discharge pressure of a discharge chamber and an intake pressure of an intake chamber to a set pressure difference in response to a value of a current supplied to a solenoid, and comprises a bleed hole provided in a body separately from a valve hole, including a leak passage smaller in diameter than the valve hole, and allowing leakage of refrigerant from a discharge chamber communication port to a crankcase communication port at a time of opening a valve portion. The bleed hole is formed to satisfy Y>2.145X+0.24, where X is a diameter of the leak passage and Y is a diameter of a bleed passage. |
