  • Method of making an actuating member for a thermostatically controlled valve
    Patent number: 4283823
    Abstract: A thermostatically controlled valve, of the type used in a cooling system of an internal combustion engine, has a temperature-responsive actuating member, for opening and closing the valve, in the form of a metal coil having shape memory effect such that its modulus of elasticity increases rapidly at a critical temperature. The actuating member is calibrated prior to assembly in the valve by heating the member to the critical temperature and reducing its length to that at which the valve will begin to open by cutting the member while preventing overheating.
