Abstract

EN UN ACCIONAMIENTO DE VALVULA CON UN EQUIPO DE CONTROL PARA ANGULO DE ABERTURA DE VALVULA VARIABLE SE ACCIONA UNA VALVULA DE INTERCAMBIO DE GAS DE FORMA INMEDIATA POR MEDIO DE UNA PALANCA DE VALVULA. PARA EL CONTROL DE POTENCIA DE UN MOTOR DE COMBUSTION INTERNA SE COMBINA EL ACCIONAMIENTO DE VALVULA DE ACUERDO CON LA INVENCION CON UN CONTROL DE DESPLAZAMIENTO VARIABLE PARA LA VALVULA DE INTERCAMBIO DE GAS. CON PREFERENCIA SIRVE COMO CONTROL DE DESPLAZAMIENTO DE VARIABLE UNA PALANCA DE VALVULA CON TRANSFORMACION CAMBIABLE.
