Pushrod for IC engine valve drive

摘要

the pushrod (1) has an annular part (17) against the side (56) of the projections (11) of an annular sector (2) facing the gas exchange valve. A shell (18) is located at the outer edge (22) of the annular part sealing the skirt (3). The shell and the annular part are made as an integral thin-walled component. In the circumferential direction of the pushrod, the projections of the annular sector form the limits of two opposite storage cavities for hydraulic fluid. There are two through passages in the skirt.
