Valve and actuator assembly for internal combustion engine, has actuator for returning valve to open position, where actuator and valve are arranged to constitute cinematic chain, and guiding module guiding translation of valve along axis
The assembly has an actuator (10) for returning a valve (20) to an open position, where the actuator and the valve are arranged for constituting a cinematic chain. The valve has a rod (22) extending in a helical spring (30) returning the valve to a closed position on a seat (15). The cinematic chain comprises a steering rack and a pinion respectively formed on the rod of the valve and the actuator, and a ring type guiding module is arranged for guiding translation of the valve along an axis of the valve.
