Abstract

UN APARATO DE BOMBEO DE COMBUSTIBLE DEL TIPO CON DISTRIBUIDOR GIRATORIO INCLUYE UNA VALVULA DE DERRAME (43) QUE SE ACCIONA POR MEDIO DE PRESION FLUIDA QUE SE PUEDE HACER OPERAR PARA FINALIZAR EL SUMINISTRO DE COMBUSTIBLE A TRAVES DE UNA SALIDA (18) DESDE UN ANIMA (14) QUE CONTENGA LOS EMBOLOS DE BOMBEO (15). LA VALVULA SE MUEVE A LA POSICION DE APERTURA POR MEDIO DE UN EMBOLO DE ACCIONAMIENTO (44). UN EXTREMO DEL CILINDRO (40) QUE CONTIENE EL EMBOLO DE ACCIONAMIENTO ESTA CONECTADO A UNA FUENTE DE BAJA PRESION (35) DE COMBUSTIBLE POR MEDIO DE UNA VALVULA DE NO RETORNO (37) Y EL MISMO EXTREMO DEL CILINDRO PUEDE ESTAR CONECTADO POR MEDIO DE UNA VALVULA DE CONTROL (26) A UNA FUENTE DE ALTA PRESION DE COMBUSTIBLE CUANDO SE PRECISA UN DERRAME DE COMBUSTIBLE. ASOCIADO CON EL EMBOLO (44) HAY UN EMBOLO DE BALANCE (46) Y LOS DOS EMBOLOS DEFINEN UN PASO FLUIDO PARA COMBUSTIBLE DESDE EL EXTREMO MENCIONADO DEL CILINDRO (40) AL ANIMA (14) PARA ASEGURAR QUE EL ANIMA ESTE COMPLETAMENTE LLENA DE COMBUSTIBLEANTES DEL SIGUIENTE SUMINISTRO DE COMBUSTIBLE A TRAVES DE UNA SALIDA.
