Abstract

LAS VALVULAS CONOCIDAS PARA INYECTAR UNA MEZCLA DE GAS CARBURANTE TIENEN UN MANGUITO DE GUIA DE GAS DE CHAPA EN SU EXTREMO POR EL CUAL CORRE UNA CORRIENTE. PARA EL AJUSTE DE LA CANTIDAD DE GAS SE EXIJE, DEBIDO A LA TOLERANCIA DEL ACABADO, LA MEDICION DE LA CANTIDAD DE GAS EN CADA UNA DE LAS VALVULAS Y EL POSTERIOR MOLDEO DE LAS GUIAS DE GAS CORRESPONDIENTES. LA NUEVA VALVULA PARA LA INYECCION DE UNA MEZCLA DE GAS DE CARBURANTE TIENE UN CUERPO DE ORIFICIOS (22) QUE CONSTA DE UNA PLETINA (24) SUPERIOR Y DE UNA PLETINA INFERIOR (25) QUE ESTAN CONFIGURADAS, POR EJEMPLO, DE SILICIO DE MONOCRISTAL. ENTRE LA PLETINA SUPERIOR (24) Y LA INFERIOR (25) HAY AL MENOS UN CANAL (28, 28''), POR EL CUAL PASA EL GAS SOBRE EL CARBURANTE DADO MEDIANTE LA ABERTURA DE PULVERIZACION (60). EL CUERPO DE ORIFICIOS Y LA VALVULA SIRVEN PARA LAS INSTALACIONES DE INYECCION DE MAQUINAS DE MOTORES INTERNOS DE CARBURANTE QUE SE ACCIONAN A DISTANCIA Y ESTAN CERRADAS HERMETICAMENTE A LA MEZCLA.
