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. In one embodiment 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 formed imparing 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. In another embodiment a U-shaped thermostatic strip has one end mounted on the base with its opposite end biased against the cover.
