PCT No. PCT/EP93/00822 Sec. 371 Date Oct. 13, 1994 Sec. 102(e) Date Oct. 13, 1994 PCT Filed Apr. 2, 1993 PCT Pub. No. WO93/21427 PCT Pub. Date Oct. 28, 1993.A valve actuating mechanism for the inlet valves E of a cylinder of an internal combustion engine has a first set of rocker arms 6 each of which actuates an inlet valve E and is actuated by a cam 2, 3, 4 for a lower engine speed range, and a second set of rocker arms 9 which are mounted between a first set of adjacent rocker arms 6 and are actuated by identical cams 8 for the higher engine speed range. The second set of rocker arms 9 is interconnected by means of a crosspiece 10. The first set of rocker arms 6 contains radially movable pistons 12 which in the higher speed range are displaced outward by oil pressure and against which the crosspiece 10 of the second set of rocker arms 9 can rest. Consequently, the valves E are actuated by the second set of rocker arms 9 as determined by the outline of the cams 8. |
