Abstract

VALVULA DE ADMISION COLOCADA EN UN MOTOR DE COMBUSTION INTERNA QUE CONSTA DE UN VASTAGO DE LA VALVULA Y DE UNA CABEZA DE LA VALVULA Y SE MUEVE HACIA ARRIBA Y HACIA ABAJO. EN CUALQUIERA DE LAS SUPERFICIES DE CONTACTO ENTRE EL VASTAGO DE LA VALVULA Y UNA GUIA DE LA VALVULA, HAY FORMADAS UNAS RANURAS ANULARES Y ALARGADAS PARA COMUNICARSE CON UN ORIFICIO DE ADMISION QUE HAY EN EL EXTREMO INFERIOR. EL ACEITE LUBRICANTE QUE INVADE UN ESPACIO ENTRE EL VASTAGO DE LA VALVULA Y LA GUIA DE LA VALVULA VA HACIA ABAJO A TRAVES DE LAS RANURAS, SALE DE LA GUIA DE LA VALVULA Y SE ADHIERE A LA CABEZA DE LA VALVULA QUE HAY EN EL ORIFICIO DE ADMISION. EL ACEITE QUE HAY SOBRE LA CABEZA DE LA VALVULA ES LAVADO HACIA ABAJO POR EL COMBUSTIBLE INYECTADO CON UN INYECTOR DE COMBUSTIBLE.
