Abstract:
A fluid level control valve has a base with an aperture formed therethrough. A cover is movably disposed over the aperture and is biased by a thermostatic element in a direction tending to close the aperture. The thermostatic element is a generally U-shaped strip having one end mounted on the base with its opposite end biased against the cover. The cover is adapted to pivot about one hinge at temperatures below a selected temperature value and pivot about a second hinge at temperatures above the selected value. A second embodiment particularly adapted to accommodate different flow rates employs a movable first hinge location.
