A displacement control valve that controls a flow rate or pressure in a working control chamber according to a degree of opening of a valve unit, comprising: a valve body having a first valve chest that communicates with first communicating passages for passing fluid at control pressure and has a first valve seat surface and a second valve seat surface, a second valve chest that has a valve hole communicating with the first valve chest and communicates with second communicating passages for passing fluid at discharge pressure, a third valve chest that communicates with third communicating passages for passing fluid at suction pressure, and a third valve seat surface provided between the second valve chest and the third valve chest; a valve element disposed in the valve body and having an intermediate communicating passage that communicates the first valve chest and the third communicating passages, a second valve section that separates from and comes into contact with the second valve seat surface to open and close the valve hole communicating with the first valve chest and the second valve chest, a third valve section that opens and closes opposite to and in conjunction with the second valve section and has a communicating hole that slides relatively to the third valve seat surface to open and close communication between the intermediate communicating passage and the third communicating passages, and a first valve section that is disposed in the first valve chest and opens and closes opposite to and in conjunction with the second valve section; a pressure-sensitive element that is disposed in the third valve chest and extends and contracts in response to suction pressure, the pressure-sensitive element having, at an extending and contracting free end thereof, a valve seat that separates from and comes into contact with the third valve section to open and close communication between the third valve chest and the intermediate communicating passage; an auxiliary communicating passage provided in the first valve section in the first valve chest for enabling communication between an interior of the first valve chest and the intermediate communicating passage; and a solenoid unit mounted to the valve body and actuating the valve element in a travel direction to open and close the valve sections of the valve element according to a current, wherein an opening area S2 between the communicating hole in the third valve section and the third valve seat surface in a control area to control the flow rate or pressure in the working control chamber is set smaller than an area S1 of the auxiliary communicating passage. a valve body having a first valve chest that communicates with first communicating passages for passing fluid at control pressure and has a first valve seat surface and a second valve seat surface, a second valve chest that has a valve hole communicating with the first valve chest and communicates with second communicating passages for passing fluid at discharge pressure, a third valve chest that communicates with third communicating passages for passing fluid at suction pressure, and a third valve seat surface provided between the second valve chest and the third valve chest;
