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 including a first valve chest that communicates with first communicating passages for passing fluid at control pressure, a second valve chest that has a second valve seat surface for a valve hole communicating with the first valve chest and communicates with second communicating passages for passing fluid at discharge pressure, and a third valve chest that communicates with third communicating passages for passing fluid at suction pressure and has a third valve seat surface; a valve element disposed in the valve body and having an intermediate communicating passage communicating with the first valve chest and the third communicating passages, the valve element having 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 separates from and comes into contact with 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 in the same direction as, and in conjunction with, the second valve section; a pressure-sensitive element that is disposed in the first 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 first valve section to open and close communication between the first valve chest and the intermediate communicating passage; an auxiliary communicating passage provided in the first valve section in the first valve chest or in the valve seat for the first valve section, 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 for 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 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, characterized in that a maximum opening area S2max between the third valve section and the third valve seat surface with the second valve section in a closed state is set equal to the area S1 of the auxiliary communicating passage. a valve body including a first valve chest that communicates with first communicating passages for passing fluid at control pressure, a second valve chest that has a second valve seat surface for a valve hole communicating with the first valve chest and communicates with second communicating passages for passing fluid at discharge pressure, and a third valve chest that communicates with third communicating passages for passing fluid at suction pressure and has a third valve seat surface;
