Valve drive for stroke valve with cam actuated roller slip lever - has circumferential groove in cam with projecting lever end engaging in it and using it as guide

摘要

The circumferences of the rollers (14) are located within the cam-sided contour (15) of the lever (1). The cam (2) has a circumferential groove (16) in a central section, to form a side guide for the lever. The lever projects radially contact-free into the groove. The common longitudinal axis (19) of the rollers extends on the side of a connection line away from the cam. The line connects the power-transmitting sections of the lever ends (5,8). The lever consists of flat material, and has upset ends. The rollers are carried on a hollow bolt (12), which passes turnably through the lever. ADVANTAGE - Guarantees side guide for lever, independent of transmission ratios, and using minimum additional methods.
