Abstract

1,134,380. Valve gear. DAIMLER-BENZ. A.G. Aug. 17, 1967 [Aug.20, 1966], No. 37956/67. Heading F1B. In I. C. engine valve gear each combustion chamber has two exhaust and two inlet valves 14, 16, Fig. 2 located in pairs in planes parallel to the rocking axes and actuated by a pair of interconnected rockers 17 and a forked rocker 11 disposed therebetween, the rockers 17 are interconnected by parallel crosspieces 19, 20 located opposite each other on either side of the rocking axis and the distance d between the rocker arm hubs is less than the sum of the maximum radii ra, rb of the respective hubs 33, 34. The rocker pair 17 and forked rocker 11 are each actuated by a single push rod 23, 22. The hub of the forked rocker is located endwise between the ends of the hubs of the rocker pair. The shafts 12, 21 are directly attached to elevated lateral walls (30), Fig. 2 on the cylinder head. In another embodiment the exhaust valves (13), Fig. 4 (not shown) are operated by the rocker pair (38) and the inlet valves (15) are operated by the forked rocker (40). The rocker pair can be of cast or welded construction or the rockers may be engaged with the crosspieces with a socket-like connection.
