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.
