Abstract: Immersed, fusible, safety valve(s) device substituting for the defective thermostat element in an engine or the like. The device is comprised of a predetermined temperature eutectic alloy fusible element (20), a valve closing antagonist spring (80), a safety holding spring (90), an extensible staple (70), a body (30), a function valve (40), a holding staple (60), a thermosensitive element (50), a pusher rod (51). To remedy the shearing efforts, the eutectic alloy is used for the weldings. In order to remedy the inconveniency of a temporary or permanent break-down, the extensible staple (70) reverses the closing device into an opening device, releases the stress and prestress elements, neutralizes the function of the thermosensitive element. The same applies when the safety device has been made by eutectic welding of the annular valve (40) to the thermosensitive element (50). This device, in these two embodiments, gives during normal and safety operation conditions a maximum flow indefinitely.

Abstract: A thermally responsive mixing valve assembly (30) supplies tempered water to an emergency shower or eyewash system. The assembly includes a valve body (31) defining hot and cold inlets (32, 33), hot and cold chambers (45, 46), a mixing chamber (48) and an outlet (34). The valve body supports a plurality of thermostatic valves (50) all in fluid communication with the hot and cold liquid chambers (45, 46) and the mixing chamber (48). The valves include a thermostat (51) operable to stroke a shuttle valve (85) within a valve liner (70). The valve liner (70) includes a number of apertures (77) in communication with the cold liquid chamber (46) and a bore (76) in communication with the hot liquid chamber (45). The shuttle valve (85) modulates to restrict hot water flow, but the flow of cold water through the apertures (77) is unrestricted. The valve liner (70) also includes cold bypass slots (78) that are normally closed by the shuttle valve (85) but that are opened upon a failure of the thermostat (51). A backseat valve (95) is provided to terminate hot water flow on thermostat failure.

Abstract: A fail-safe thermostat (10, 70) includes a stationary valve member (24) configured to be positioned between conduit components (12, 20) of the engine cooling system, a movable valve member (38) for engaging a valve seat (28) to block fluid flow into a conduit (22) through an opening formed by valve seat (28), an operating spring (48) for biasing the movable valve member (38) to a closed position against the valve seat (28) of the stationary valve member (24), and a thermally responsive actuator (32) for moving the movable valve member (38) to an open position away from a valve seat (28) when the ambient temperature exceeds a first predetermined temperature to permit fluid flow into the conduit (22). The apparatus further includes a bimetallic frame member (46) coupled to the stationary valve member (24). The frame member (46) is configured to compress and hold the operating spring (48) in engagement with the movable valve member (38). The frame member (46) is configured to disengage itself from the stationary valve member (24) when the ambient temperature exceeds a second predetermined temperature and upon failure of the movable valve member (38) to move to its open position.
