Abstract

There is provided a thermally controlled valve having a valve seat, a closure valve associated therewith, an expansion capsule containing an evaporation medium which actuates the closure valve by a stroke displaceable wall part, and a snap spring biasing the closure in the opening direction and arranged so that in the closed position of the valve, the spring occupies a position of stroke lying in the range of stroke between the force maximum and the force minimum of its force stroke characteristic.
