Abstract

UN APARATO PARA BOMBEO DE COMBUSTIBLE TIENE UN PULSADOR (13) DE BOMBEO OPERABLE MEDIANTE UNA LEVA (14) QUE SUMINISTRA COMBUSTIBLE A UN ORIFICIO DE SALIDA. UNA VALVULA DE ESCAPE (22) SE PROVEE PARA PERMITIR LA SALIDA DE COMBUSTIBLE A PARTIR DE UNA APERTURA DEL AGUJERO (12) EN DONDE SE LOCALIZA EL PULSADOR DE BOMBEO. UN PISTON DE ACCIONAMIENTO (27) ESTA SITUADO EN UN PRIMER CILINDRO (24) Y ESTA ACOPLADO A LA VALVULA DE ESCAPE, Y UN PISTON DE ALMACENAMIENTO (28) ESTA SITUADO EN UN SEGUNDO CILINDRO (25) CONECTADO AL PRIMER CILINDRO. UNA VALVULA DE CONTROL (35) CONTROLA LA PRESION EN EL PRIMER CILINDRO Y CUANDO LA PRESION SUBE EL PISTON QUE ACTUA A LEVA, LA VALVULA DE ESCAPE ASCIENDE DESDE SU ASENTAMIENTO Y EL COMBUSTIBLE PUEDE FLUIR DESDE EL AGUJERO HACIA EL PRIMER CILINDRO, Y CUANDO EL PISTON ACTUANTE SE DESPLAZA DESDE ALLI, HACIA EL SEGUNDO CILINDRO.
