    摘要： A fail-safe thermostat for vehicular cooling systems is positioned in a junction leading to an internal coolant passageway, a radiator passageway and a bypass passageway. An open housing seated in the junction supports a fixed central rod extending into the wax filled interior of a movable cylindrical member which controls the position of the interior segment of a main valve. Expansion of the wax forces the cylindrical member in a first direction against a compression spring. Fusible alloy is disposed in the coupling between the cylindrical member and the main valve, and melts at a specific temperature range in excess of the normal range. When this occurs the coupling is released in such a way that the spring forces the valve member to a second limit position opposite to the direction of expansion. A bypass closure member at one end of the cylindrical member may be used to close the bypass passageway concurrently with increased temperature.

    摘要： A heat sensitive locking device is preferably provided for a fluid actuator of the type which is moved in a direction to one position through the application of fluid pressure and remains in such position unless temperature conditions surrounding the device reach a level indicating that the actuator should be shifted to another position. The locking device comprises a core attachable to an exposed end of, for example, the piston shaft, and an annular collar surrounding such core and attached to the cylinder. A plurality of annular segmental shaped locking members are disposed between the core and collar and pivotally mounted so as to be movable to a locking position or to an unlocked position, each relative to the core. The annular locking elements are held in their locking position by being wrapped by a resilient spring wire, the ends of which are anchored to the locking members by means including a minimal size fusible link.
