Abstract (en)
[origin: US4671222A] A device for actuating valves in an internal combustion engine comprise four valves (9, 10, 11, 12) inclined in a V configuration and a central spark plug (3) per cylinder (6), each cylinder (6) being associated with two pairs of valves (9, 10; 11, 12) inclined on each side of an axial plane (PP) of the cylinder (6), while a spark plug pit (4) is provided between the two valves (9, 10) of one of the pairs, roughly parallel to the latter, this device comprising a central camshaft (13) located in the vicinity of the axial plane (PP) and, for each cylinder (6), at least two rockers (14, 15). There is interposed between each rocker (14, 15) and the camshaft (13) a pushrod (21) parallel to the cylinder (6), and, for each cylinder, the pin (18) of the rocker(s) disposed on the same side as the pit (4) is carried, as the other pin (19), by two bearings (26) located on each side of the rockers (14, 15) and is disposed between the pit (4) and the axial plane (PP). This device is of small overall size and particularly reliable.
