ABSTRACT:
There is provided a locking element and a thermostat incorporating same for use in a liquid-cooling system. The locking element has a body portion and an end portion for attaching the locking element to the thermostat. In first and second embodiments, a tab extending from the body portion locks the displaceable valve of the thermostat in an open position when the valve has been displaced a pre-determined amount. In the first embodiment of the locking element, at least one aperture is defined in the end portion to attach the end portion to a lower bridge of the thermostat. In this embodiment, two locking elements are attached to the thermostat on opposing sides of the displaceable valve. In a second embodiment of the locking element, the end portion rests against the bottom member of the lower bridge of the thermostat. In this embodiment, two body portions extend from the end portion to opposing sides of the displaceable valve. In a third embodiment, the end portion abuts against the upper bridge and the body portion abuts against the displaceable valve. In this embodiment, the body portion springs to lock the displaceable valve when it had been displaced a pre-determined amount.
