Abstract

Disposición de ajuste de recorrido de válvula (10) para una disposición de accionamiento de válvula (11) controlable mecánicamente, con al menos una disposición de palanca intermedia (12), presentando la disposición de palanca intermedia (12) al menos una palanca intermedia (18) con una curva de trabajo (24), que está alojada al menos a través de un primer rodillo (14) de manera móvil en un carril de corredera (13), y que está en conexión operativa con una disposición de árbol de levas (22) y con una instalación de regulación de recorrido de válvula (16), actuando la disposición de árbol de levas (22) a través de otro rodillo (41) sobre la disposición de palanca intermedia (12) y presentando la instalación de regulación de recorrido de válvula (16) un árbol de excéntrica giratorio (17), que actúa a través de un segundo rodillo (20) que se encuentra en un eje de apoyo (30), sobre la disposición de palanca intermedia (12), caracterizada por que el eje de apoyo (30) está alojado de manera excéntrica, de tal manera, que el segundo rodillo (20) está alojado de manera excéntrica y presenta un punto de ataque de herramienta (36) para la alineación del segundo rodillo (20) y con ello de la disposición de palanca intermedia (12), proporcionándose en ambos lados del eje de apoyo (30) un casquillo (38) o un resalte, con lo que se garantiza la disposición excéntrica del eje de apoyo (30), de tal manera que al girar un ángulo α, un punto circunferencial del segundo rodillo (20) describe una forma de arco distinta de un arco circular.
