ENSEMBLE D'UNE SOUPAPE DE MOTEUR A COMBUSTION INTERNE SANS ARBRE A CAMES ET D'UN ACTIONNEUR

摘要

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.
