ABSTRACT:
This application concerns a leaf type spring for closing valves in a cylinder head of an internal combustion engine. Specifically, the leaf spring has an edge base which is attached to the cylinder head and a cantilevered unsupported portion which extends therefrom. The unsupported portion is bifurcated to form two arms, each arm engaging a valve in a manner biasing it towards its closed operative position and yieldably permitting the valve to be moved toward its open operative position.
