Abstract

UN APARATO DE BOMBEO DE COMBUSTIBLE DE TIPO DE DISTRIBUIDOR GIRATORIO INCLUYE UN EMBOLO DE BOMBEO PRINCIPAL 12 Y UN EMBOLO AUXILIAR 20 ACCIONABLE AL MISMO TIEMPO POR UNA LEVA. DURANTE EL MOVIMIENTO HACIA ADENTRO, EL EMBOLO DE BOMBEO DESPLAZA EL COMBUSTIBLE HACIA UNA SALIDA 15. EL EMBOLO AUXILIAR 20 DESPLAZA EL COMBUSTIBLE A UNA PERFORACION DE LANZADERA 33 QUE CONTIENE UNA LANZADERA 34 Y, DURANTE EL MOVIMIENTO HACIA ADENTRO INICIAL, SE ABRE UN PRIMER TRAYECTO DE CIRCULACION 45, 46 PARA EL DRENAJE DE LA PERFORACION 11 QUE CONTIENE EL EMBOLO DE BOMBEO, PERO SE CIERRA AL PRODUCIRSE EL MOVIMIENTO ADICIONAL DE LA LANZADERA HASTA QUE SE ABRE UN SEGUNDO TRAYECTO DE CIRCULACION 45, 41, 43. EL SEGUNDO TRAYECTO DE CIRCULACION INCLUYE UNA GARGANTA 41 QUE TIENE UN BORDE INCLINADO 42, DE MODO QUE EL AJUSTE ANGULAR DE LA LANZADERA DETERMINA LA CANTIDAD DE COMBUSTIBLE QUE SE SUMINISTRA A TRAVES DE LA SALIDA. CUENTA TAMBIEN CON UNA VALVULA 38 PARA PERMITIR DESPLAZARSE AL COMBUSTIBLE POR ACCION DEL EMBOLOAUXILIAR DE MODO QUE FLUYA A UN DRENAJE.
