Abstract
A fluid level control valve has a base with an aperture formed therein. A cover is slidingly disposed over the aperture and is biased by a thermostatic element in a direction tending to close the aperture. The thermostatic element is an elongated strip having one end captured by tabs projecting from the base, and an opposite end is captured by a bracket formed on the base. The thermostatic element is formed with a V-shaped force imparting portion which is aligned with the cover and the position of the bracket is adjustable to place a selected force on the cover through the thermostatic element. The calibrated valve is then fixedly attached to a housing with the aperture aligned with an aperture in the housing.
