Abstract

519,189. Valves. HEMMINGSEN, T. V. Sept. 16, 1938, No. 27038. Convention date, Sept. 17, 1937. [Class 7 (vi)] A valve spring for internal-combustion and other engines comprises a hairpin or U-shaped laminated spring' which is pivoted at or near its closed end 10 and has its free ends 5, 6 bearing against members 3, 4, the latter of which is fixed while the former is attached to the valve 14. In a modification, the pivot 10 is at the centre of the closed end of the spring, and the ends 5, 6 engage rollers ; or one of these ends may be fixed and the spring have a slight\ longitudinal play at the pivot 10. The spring may be at the same side of the valve as the actuating-lever 2, or at the opposite side ; in the former case there is a spring member at each side of the lever. Also two or more spring members may be arranged one above the other and interconnected by links.
