A thermostatic valve for an internal combustion engine, including a housing with a plurality of coolant connections for connection to a coolant circuit of the internal combustion engine, a valve element which is mounted movably in the housing such that a movement of the valve element, at least two coolant connections of the housing are either connectable to one another or separable from one another, an expansion element which is arranged in order, during the operation of the internal combustion engine, to enter into thermal contact with coolant circulating in the coolant circuit, wherein, in the event of a heat-induced expansion, the expansion element moves the valve element in the housing in order to connect the at least two coolant connections, wherein a controllable heating device is provided such that the expansion element can be heated in order to move the valve element.
A thermostatic valve for an internal combustion engine, comprising a housing (10) with a plurality of coolant connections (12, 14) for connection to a coolant circuit of the internal combustion engine, furthermore comprising a valve element (16) which is mounted movably in the housing (10), wherein, by means of a movement of the valve element (16), at least two coolant connections (12, 14) of the housing (10) are either connectable to one another or separable from one another, furthermore comprising an expansion element (24) which is arranged in order, during the operation of the internal combustion engine, to enter into thermal contact with coolant circulating in the coolant circuit, wherein, in the event of a heat-induced expansion, the expansion element (24) moves the valve element (16) in the housing (10) in order to connect the at least two coolant connections (12, 14), wherein a controllable heating device (32, 34) is provided by means of which the expansion element (24) can be heated in order to move the valve element (16), wherein the valve element (16) is movable in the housing (10) between a closed position separating the connection between the at least two coolant connections (12, 14) and a completely open position, wherein, as the valve element (16) moves over a first adjustment path from the closed position to an intermediate position that is between the closed position and the completely open position, the valve element (16) opens up and maintains a constant flow cross section between the at least two coolant connections (12, 14), wherein, as the valve element (16) moves from the intermediate position to the completely open position, the valve element (16) further opens up a flow cross section between the at least two coolant connections (12, 14), said flow cross section increasing until the valve element (16) is in the completely open position.
