PURPOSE:To obtain the titled thermostat with which the time for injecting the cooling water into an engine can be sharply reduced when the thermostat is first incorporated into the engine and is capable of performing the normal function once the engine is started by a method wherein a thermosensitive element, a main valve and a resilient space keeping member are provided. CONSTITUTION:In a condition in which the engine is not started, the space keeping member 7 bends a leaf spring 7b and is kept projecting into a path in which the main valve 3 moves toward a valve seat 4a while, in this case, the thermosensitive element 1 does not expand so that the main valve 3 is pressed against the valve seat 4a by a spring 2 and is in engagement with the leaf spring 7b. Accordingly, air is removed well at the time of injection of the cooling water into the engine since the main valve 3 is opened and not much time is required for the injection. Thus, when the engine is started, the main valve 3 moves downward through the operation of the thermosensitive element 1 to thereby make the thermostat perform the normal operation. |
