Abstract

123,578. Phillips, R. E., (Burt, S. J.). Feb. 26, 1918. Valve-gear.-Positive means is employed to open and also partly to close a valve, the final closing movement being effected by a spring. The two positive movements may be effected by a pair of cams d, d<1> of equal or slightly different lift bearing on a pair of rollers carried either directly on the tappet rod or as shown on a bell-crank lever m, one arm of which works between pins n on the valve spindle. In the former case, a helical spring, and in the latter a blade spring h is employed.
