Valve operating mechanism for gas exchange valve of diesel engine, has non-adjustable oscillating arm that is shifted in direction of base circle of cam at sliding surface over circular arc-shaped upper surface of adjustable oscillating arm

摘要

The mechanism has an adjusting equipment with an adjustable oscillating arm (17) that cooperates with an eccentric shaft and a cam. The arm has a circular arc-shaped sliding surface (20), which is arranged coaxially in the form of a cylinder segment surface. A non-adjustable oscillating arm (27) is shifted in the direction of a base circle of the cam at the sliding surface over a circular arc-shaped upper surface of the arm (17).
