Abstract

Disposición de mando de válvula para un motor de combustión interna, - en la que una leva de mando (2) de un árbol de levas (4) actúa con efecto de mando sobre una válvula de carrera rectilínea (7) a través de un segmento basculante (5) en un empujador (6), a cuyo fin - el segmento basculante (5) formado con una pista de contacto (8) solicitada por la leva de mando (2) está dispuesto móvil y guiado en el empujador (6) a través de un sector de arco de círculo (10) concéntrico al eje de giro (9) del árbol de levas, de tal manera que - se logra en cada carrera de la válvula por medio de un dispositivo de mando (11) un acoplamiento de la pista de contacto (8) determinante de las fases de apertura y cierre de la válvula de carrera rectilínea (7) con los flancos de la leva de mando giratoria (2) a través de un movimiento de basculación (flecha "A") del segmento basculante (5) contro lado forzosamente en el mismo sentido y/o en sentido contra rio con relación al sentido de giro de la leva de mando (2), caracterizada porque - el dispositivo de mando (11) comprende un balancín de empuje (14) guiado en la dirección de la carrera de la válvula (flecha "B") a través de una primera articulación corrediza-giratoria (12) dispuesta por el lado de la carcasa del motor y otra articulación corrediza-giratoria (13) prevista por el lado del segmento basculante, con una perforación de mando (15) atravesada con holgura por un sector del árbol de levas (4) exento de leva de mando, - en cuyo perímetro ataca un elemento maniobrable de forma controlada (anillo de guía 20) de un mecanismo de regulación (16) dispuesto en/sobre el árbol de levas (4) girando juntamente con éste de tal manera que - el balancín de empuje (14) regulable en la dirección de la carrera de la válvula (flecha "B") con la perforación de mando (15) excéntricamente al eje de giro (9) del árbol de levas realiza a cada carrera de la válvula, mientras gira el árbol de levas (4), un movimiento de oscilación periódico (flecha "A") que sirve para el mando forzoso del segmento basculante (5), transversalmente a la dirección de la carrera de la válvula (flecha "B"), en superposición de un movimiento de empuje producido en la dirección de la carrera de la válvula (flecha "B").
