Abstract

SE PROPONE UN DISPOSITIVO DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA, EN EL QUE UNA VALVULA DE INYECCION DE COMBUSTIBLE MUESTRA UN TAQUE (21) QUE ACCIONA EL ELEMENTO DE VALVULA DE INYECCION Y QUE LIMITA UNA CAMARA DE CONTROL (25) QUE ES ABASTECIDA CONSTANTEMENTE POR UN ESTRANGULADOR (27) CON COMBUSTIBLE DE ALTA PRESION, PUDIENDO SER DESCARGADO A TRAVES DE UNA VALVULA DE CONTROL (36) Y UN CANAL DE SALIDA (129). LA VALVULA DE CONTROL (36) MUESTRA PARA ELLO UN ELEMENTO DE VALVULA (44) QUE ES ACCIONADO POR UN ELEMENTO PIEZOELECTRICO (35) DE MANERA QUE, CUANDO EL CANAL DE SALIDA (129) SE ABRE, EL ELEMENTO DE VALVULA SE MUEVE HACIA LA CAMARA DE CONTROL (25). EN POSICION DE CIERRE, EL ELEMENTO DE VALVULA (44) ES ACCIONADO EN LA DIRECCION DE CIERRE DEBIDO A LA PRESION EXISTENTE EN LA CAMARA DE CONTROL (25).
