Abstract: The use of devices to simultaneously actuate multiple valves operatively associated with a common combustion chamber is becoming more important due to the increase in multiple valve internal combustion engines. The ability to simultaneously actuate multiple valves reduces weight, costs, and parts in the engine. The subject valve actuation device (10) has a valve arrangement (12) with at least three valves (14, 15 and 16) having stem portions (40, 41 and 42) operatively associated with a common combustion chamber (22). A free-floating bridge (62) having three recesses (64, 65 and 66) is seated on the stem portions (40, 41 and 42). A movable rocker arm (34) having two fingers (36 and 37) contacts the free-floating bridge (62) at locations sufficient to actuate the valves (14, 15 and 16) simultaneously.

Abstract: In a reciprocating piston internal combustion engine with three inlet valves per cylinder which are individually actuated directly by cams on an inlet camshaft via pushrods and are arranged obliquely to the central cylinder axis, where the central inlet valve is at a smaller angle to the central cylinder axis than the other two, the central inlet valve begins to open later than the other two; thus the valve recess in the piston head for the valve disk of the central inlet valve becomes flatter or altogether inexistent in a high-compression internal combustion engine. Likewise, in an internal combustion engine with three outlet valves, the central outlet valve closes earlier than the other two.

Abstract: A variable valve timing mechanism for an internal combustion engine wherein the camshaft is supported at one end by a combined bearing and valve body member that is detachably connected to the supporting engine body. The connection is such that fluid from the engine lubricating system can be delivered to this body and distributed by a control valve mounted in it. This simplifies machining of the engine body and permits a more compact, lower cost construction without sacrificing any function. The control valve is mounted in a bore that is accessible through the side of the cylinder head and is actuated by a servo motor mounted on the exterior of the cylinder head to provide a compact, rigid and easily serviced assembly.
