Abstract

512,632. Valves. SULZER FRERES SOC. ANON. March 9, 1938, No. 7336. Convention date, April 6, 1937. [Class 135] A spring-leaf type of valve for passing scavenging or charging air to two-stroke internal combustion engines &c. comprises a number of spring leaves c fixed at one end and co-operating with seating surfaces f provided on supporting members e to control a passage a. The under surfaces of the supporting members e are curved to act as stops for the spring leaves and are provided with ribs h so that the area of contact is reduced to prevent the spring leaves sticking to these surfaces. The radius of curvature of the ribs h is reduced from the end adjacent the fixed ends of the spring leaves, to the end adjacent the free ends of the leaves, thus preventing wear owing to the shock of the spring leaves striking the stop surfaces. The free ends of the leaves are further of such length as to project beyond the ends of the seating surfaces f.
