Abstract

UN APARATO DE BOMBEO DE COMBUSTIBLE DEL TIPO DE DISTRIBUCION ROTATORIA, COMPRENDE UN ELEMENTO 12 DISTRIBUIDOR, GIRATORIO EN UN CUERPO 10, EN RELACION TEMPORIZADA CON UN MOTOR ASOCIADO; UN PISTON DE BOMBEO, ALOJADO DENTRO DE UNA PERFORACION 13 Y MOVIL HACIA DENTRO PARA DESPLAZAR EL COMBUSTIBLE AL MOTOR ASOCIADO, POR MEDIO DE UNA LEVA 138 Y UN ELEMENTO 23 DE VALVULA, DESVIADO A RESORTE A LA POSICION CERRADA, Y QUE PUEDE DESPLAZARSE A UNA POSICION ABIERTA PARA PERMITIR LA SALIDA DEL COMBUSIBLE DESDE LA PERFORACION 13, MEDIANTE LA PRESION DEL FLUIDO APLICADA A UN EMBOLO 26, QUE ESTA ACOPLADO AL ELEMENTO DE VALVULA. EL FLUIDO A PRESION SE APLICA AL EMBOLO BAJO EL CONTROL DE UNA LANZADERA DESPLAZABLE 34, QUE OPERA MEDIANTE OTRO PISTON EN RELACION TEMPORIZADA CON EL PRIMER PISTON MENCIONADO. LA EXTENSION DEL MOVIMIENTO DE LA LANZADERA ANTES DE QUE SE APLIQUE FLUIDO A PRESION AL EMBOLO 26 PUEDE CONTROLARSE, EN FORMA QUE SE DETERMINE LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO AL MOTOR ASOCIADO.
