Abstract
A valve housing () has first and third openings (), and first and second actuating elements () that are movable along a longitudinal axis of the housing (). A return element () is between the actuating elements (), and exerts a force to keep the actuating elements () in a rest position to close or open the first and third openings (). First and second wires () are formed from a shape memory alloy. The first wire () is on the first actuating element () and the second wire () is on the second actuating element (). An electric current to the first or second wire () contracts the respective wire () and moves the corresponding actuating element () into an activated position against the force exerted by the return element ().
