ABSTRACT:
A valve body includes a base section having an inlet and an outlet and means forming a valve seat therebetween. A flexible diaphragm is supported for movement relative to the valve seat and includes a center by-pass port which is opened and closed by a valve member supported for axial movement by a closure section of the valve body. A pin-like actuating lever is pivotally supported by a flexible seal secured to the closure section and has an inner end portion projecting into an opening formed within the valve member. An elongated U-shaped bimetallic actuating element is mounted on the closure section generally parallel to the lever and includes a movable head portion. The bimetallic actuating element is preferably connected as a resistance in series with an electrical load, and a spring is compressed against the outer end of the actuating lever to cause rapid snap-action movement of the lever, and the valve member in response to slower movement of the head portion of the actuating element. In a modification, the bimetallic actuating element is located within a cup which is formed as a part of the valve body and is positioned to receive an overflow of water from a tank which is supplied with water through the valve. The valve body may be supported by an internally threaded tubular fitting having a flange with peripheral teeth for engaging a support bracket and providing for angular adjustment relative to the bracket.
