Abstract
A temperature responsive valve is disclosed including a pair of body members which are snapped together and when assembled define a valve chamber. Located within the valve chamber is a bimetal snap disc which seats at its periphery against an O-ring type valve seat when in one position of stability and is spaced from the valve seat in its other position of stability. A spider type spring extends between the cover member and the center of the disc to urge the disc in a direction toward the valve seat. The spring is provided with depending tabs which are positioned adjacent to the side wall of the cavity and function to insure proper location of the spring during assembly of the cover member. The tabs also function to insure proper position of the disc during the operation of the valve.
