Abstract: The invention relates to valve control means for a push-rod internal combustion engine. With reference to FIG. 8 of the drawings, the valve control means comprises valve means, cam means comprising a camshaft having a first cam member and a second cam member having a different profile from the first cam member, and means for transmitting reciprocating movement to the valve means from the cam means. The means for transmitting reciprocating movement comprises a first cam follower member in engagement with the push-rod and a second cam follower member movable relative to the first cam follower member, and locking means to enable the follower members to be linked to move together. When the cam follower members are not linked the valve means is controlled by the first cam follower member in engagement with and following the profile of the first cam member, and when the cam follower members are linked the valve means is controlled by the second cam follower member in engagement with and following the profile of the second cam member.

Abstract: The invention relates to a valve control system for a push-rod internal combustion engine. The valve control system includes a cam including a rotatable cam shaft having a first cam member and a second cam member having a different profile from the first raised portion. A reciprocating movement is transmitted by a rocker arm engaging the valve and a push-rod connected to a first cam follower in engagement with a push-rod operating a rocker arm and a second follower capable of movement relative to the first cam follower with locking device to enable the cam follower members to be linked so as to be moved together. When the cam follower members are not linked, the valve is controlled by the first cam follower in engagement with and following the profile of the raised portion and when the cam follower members are linked, the valve is controlled by the second cam follower in engagement with and following the profile of the second cam member, thus allowing the selection of one cam or another to accommodate different operating conditions of the engine.

Abstract: The valve control means for an internal combustion engine comprises valve means (10), cam means comprising a camshaft (30) having a first cam member (23) and a second cam member (26) having a different profile from the first cam member (23) and means (18) for transmitting reciprocating movement to the valve means (10) from the cam means (23 or 26). The means (18) for transmitting reciprocating movement comprises a first cam follower member (20) in engagement with the valve means (10) and a second cam follower member (21) movable relative to the first cam follower member (20), and locking means (27) to enable the follower members (20 and 21) to be linked to move together. When the follower members (20 and 21) are not linked the valve means (10) is controlled by the first cam follower member (20) in engagement with and following the profile of the first cam member (23) and when the follower members (20 and 23) are linked the valve means (10) is controlled by the second cam follower member (21) in engagement with and following the profile of the second cam member (26).
