Title (EN) VARIABLE VALVE TIMING
(FR) REGLAGE VARIABLE DES SOUPAPES
Abstract:
(EN) A means of varying both the opening and closing angle of internal combustion engine cam-operated valves (13) by means of a mechanism which responds to the torque applied to the camshaft (5) by the valve springs (14) in such a way that the opening angle of the valves (13) is retarded and the closing angle is advanced and in which a means (11) of inhibiting this operation can be incorporated.
(FR) Dispositif servant à varier à la fois l'angle de fermeture et d'ouverture de soupapes (13) actionnées par cames d'un moteur à combustion interne, par l'intermédiaire d'un mécanisme sensible au couple appliqué à l'arbre à came (5) par les ressorts de soupape (14), de telle manière que l'angle d'ouverture des soupapes (13) est retardé et l'angle de fermeture est avancé, et dans lequel des moyens (11) servant à inhiber cette opération peut être inclus.
