Abstract

473,468. Valves. TEBALDI, A. March 20, 1937, No. 8288. Convention date, March 20, 1936. [Class 7 (vi)] The valves of a pair of engine cylinders are closed by a coiled spring which is arranged between the two valves and which at one part acts on one valve and at another part is keyed to a drum having an arm acting on the other valve. The Figure shows the stems 2, 21 of the two valves, with a spring 8 between them comprising two helical coils joined by an intermediate loop 9 which constitutes an arm acting on the valve 2, the arm 6 acting on the other valve being formed with a rotatable drum 4, to the ends of which are anchored the outer ends 10 of the helical coils. In a modification, the coils of the spring are exterior of the drum 4, which is mounted in ball bearings. A spring with a single coil might be used.
