Nockenstößel-Kipphebel zur Betätigung von zwei Ventilen

A rocker arm of the cam-follower type simultaneously operates two valves of a cylinder of an internal combustion engine. The rocker arm includes an intermediate portion and two end portions. The intermediate portion has upwardly extending side walls and end walls forming a large generally rectangular opening at the top edges thereof. The side walls have aligned holes carrying an axle on which is rotatably mounted a roller which contacts an overhead cam. One end portion of the rocker arm has a downwardly-facing recess to engage an upper end of a lifter post. The other end portion of the rocker arm has a long, narrow web with downwardly-facing pads near the ends thereof and in predetermined, spaced relationship. The pads engage upper ends of two valve stems for simultaneously operating valves to which the stems are connected.
