Abstract

168,301. Santagiuliana, A. Aug. 25, 1920, [Convention date]. Regulating; valvegear. - In a twostroke - cycle engine compressing the new charge in the crank case, a full charge is introduced into the cylinder at all loads so as to ensure complete scavenging, and governing is effected by returning part of the charge to the crank case during t h e compression stroke through a valve 10 in the cylinder head. As shown, this valve is actuated when necessary by an overhead lever and a tappet rod which is engaged by a rocker 18, Fig. 3, pivoted at 17 on the end cover 8' of the crank case. The rocker 18 carries a roller 19 engaged by a cam on the crank-shaft, and the pivot 17 is carried by a disc 15 adjustable about the shaft. When the pivot 17 is in the line of movement of the tappet-rod, the oscillation of the rocker does not open the valve 10, but the disc 15 may be turned so as to displace the pivot 17 until the valve 10 is opened to the required extent.
