<p>A thermostatic control valve for maintaining an essentially constant set value of an operating temperature of a liquid coolant conductible through a cooling jacket of an internal combustion engine with a valve chamber open to a first valve connection and with a valve controlling the coolant connection between a second valve connection and the valve chamber and a further valve controlling the coolant connection between a third valve connection and the valve chamber. A thermostatic adjusting element, responsive with adjusting movements to temperature changes, is operatively connected with the valves so as to selectively actuate the same. One of the valves is actuatable for suppression of a coolant flow in the cooling jacket by a spring means abutting a fixed thrust bearing mounted on the valve chamber with the other valve being actuatable by the adjusting element into a closed position. One of the valve connections is connectable to a suction side of a coolant pump having a pressure side connected to a cooling jacket of the internal combustion engine.</p> |
