A fail-safe thermostat includes a stationary valve member configured to be positioned between conduit components of the engine cooling system, a movable valve member for engaging the valve seat to block fluid flow into the conduit through the opening, an operating spring for biasing the movable val...
FAIL SAFE THERMOSTATOF THE DISCLOSUREThis invention pertains to a temperature dependent electric current\nregulator-or-limiting circuit element for electrical appliances, espec-\nially electrically heated appliances; with an automatic switchable\ncontact pair which is activated by a predetermined given ...
A fail-safe thermostat valve for controlling the flow of coolant to an engine has, in addition to a thermostat element that expands and contracts to open and close the valve, a fusible element that supports an elevated plate that holds two springs. One spring holds the valve plate in its ...

A fail-safe thermostat for vehicular cooling systems is positioned in a junction (13) leading to an internal coolant passageway, a radiator passageway and a bypass passageway (19). An open housing seated in the junction supports a fixed ... ...
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 ...
A system for converting the failure mode of a motor vehicle type thermostat whereby a secondary cooling fluid passage, connected in parallel to the primary (thermostat-controlled) cooling fluid passage, is established. The by-pass valve means of the secondary passage is normally open and is closed...
