Abstract

Un dispositivo de operacion de valvula para un motor de combustion interna es capaz de aumentar una duracion de traslape de valvula negativo cuando cantidades de elevacion maximas de la valvula de admision y una valvula de descarga son pequenas. El dispositivo V de operacion de valvula se proporciona con mecanismos Mi y Me de ajuste caracteristico de lado de admision y de lado de descarga para ajustar las caracteristicas de operacion de una valvula 7 de admision y una valvula 8 de descarga. Cada mecanismo. Mi o Me de ajuste caracteristico tiene una leva 14 de control que gira integralmente con una flecha 13 de leva, un motor 30 electrico que ocasiona que un sujetador 15 pivoteado en la flecha 13 de leva gire alrededor de la flecha 13 de leva, una palanca 16 de suboscilador pivoteada en el sujetador 15 y que se hace oscilar mediante la leva 14 de control, y una leva 18 de valvula que se hace oscilar alrededor de la flecha alrededor de la flecha 13 de leva mediante oscilacion del sujetador 15 y la palanca 16 de suboscilador, para ocasionar la oscilacion de las palancas 10 y a 11 de oscilador principal. El motor 30 electrico ocasiona que el sujetador 15 oscile de tal manera que la temporizacion de apertura de valvula de la valvula 7 de admision se retarda a medida que la cantidad de elevacion maxima de la valvula 7 de admision se hace menor y la temporizacion de cierre de valvula de la valvula 8 de descarga se hace avanzar a medida que la cantidad de elevacion maxima de la valvula 8 de descarga se hace menor.
