Abstract

Palanca de accionamiento de válvula para transmitir el movimiento de una leva dispuesta sobre un árbol de levas a una válvula de cambio de gases de un motor de combustión interna, con: un cuerpo base (1) alargado, conformado esencialmente sin arranque de virutas, que está configurado de forma esencialmente simétrica con respecto a un plano longitudinal de simetría (2) que se extiende en su dirección longitudinal una zona de contacto de válvula (20) dispuesta en un primer extremo de este cuerpo base, dos orejas (25, 26; 51, 52) dispuestas a ambos lados de dicho plano longitudinal de simetría, en la zona de contacto de válvula, que presentan en cada caso una supeficie lateral (23, 24; 60, 61) orientada hacia el plano longitudinal de simetría, estando conformadas dichas orejas en dicho cuerpo base y dobladas hacia la zona de contacto de válvula, caracterizada porque dichas orejas están dispuestas en un borde de extremo (30) del cuerpo base alargado con una separación (a) que es más pequeña quela separación (b) de las superficies laterales en la zona de contacto de válvula, determinándose dicha separación en cada caso en una dirección perpendicular al plano longitudinal de simetría (2), y porque como mínimo una de estas orejas presenta como mínimo una zona de transición (35, 36; 54, 58) que se extiende alejándose del plano longitudinal de simetría, en la que la distancia entre dichas superficies laterales aumenta, y como mínimo una zona paralela (37, 38; 55, 59) en la que se extienden dichas superficies laterales de forma esencialmente paralela al plano longitudinal de simetría (2).
