Abstract

Dispositivo para la variación del ángulo de giro relativo del árbol de levas de un motor de combustión interna respecto de una rueda de accionamiento, con una pieza interior 2 unida solidaria en rotación al árbol de levas (1), que presenta nervios o alas (4a a 4d) que discurren al menos aproximadamente radiales, y con una rueda celular (5) accionada, que presenta varias células distribuidas a través del contorno limitadas por nervios (6a a 6d), que por los nervios o alas de la pieza interior conducidos movibles angularmente en su interior se subdividen en dos cámaras de presión (7a a 7d, 8a a 8d), de manera que con su impulso de presión o descarga de presión el árbol de levas es giratorio por medio de los nervios o alas entre dos posiciones finales respecto a la rueda celular, caracterizado porque la variación de la posición de giro es amortiguada hidráulicamente por medios de amortiguación (21, 22; 25, 26; 32) integrados antes de alcanzase una de las dos posiciones finales, estando realizados los medios de amortiguación como estrangulador de amortiguación (32).
