Abstract

269,033. Newson, S. C., and Laystall Motor Engineering Works, Ltd. Aug. 4, 1926. Valves; valve gear. -The valve i is acted on by a leaf spring a pivoted at c and provided with a stud or roller e which, during the opening of the valve by a cam m and lever n, enters a recess o formed in the cam so as to relieve the spring pressure during opening.
