Operating temperature-dependent actuator element, involves reducing heat supplied to expansion material on reaching defined force exerted by expansion material on membrane

摘要

The method involves at least reducing the heat supplied to an expansion material (3) in a metal housing enclosed by a lid on reaching a predefined force exerted by the expansion material on a membrane (4) and hence on a rod (5) and increasing the supplied heat again on falling below the defined force again. An independent claim is included for a temperature-dependent actuator element.
