Abstract

UNA BOMBA DE INYECCION DE COMBUSTIBLE DEL TIPO DE DISTRIBUIDOR DISPONE DE UN EJE (19) DISTRIBUIDOR ACOPLADO DE FORMA RIGIDA A UN EJE (13) DE ACCIONAMIENTO. CUANDO GIRA, EL EJE DISTRIBUIDOR SUMINISTRA DE FORMA SUCESIVA A LAS TOBERAS (29) DE INYECCION COMBUSTIBLE A PARTIR DE UNA BOMBA CON CAMARA (22) DE TRABAJO. LOS PISTONES (21) DE BOMBA ESTAN MONTADOS DE MODO DESPLAZANTE CADA UNO DE ELLOS EN UNA PERFORACION (20) RADIAL A LO LARGO DE UNA PLURALIDAD DE TALADROS (20) RADIALES DISPUESTOS EN EL EJE (19) DISTRIBUIDOR. LOS PISTONES (31) DE BOMBA DELIMITAN POR UNA PARTE LA CAMARA (22) DE TRABAJO DE BOMBEO Y POR OTRA PARTE ESTAN CONECTADOS DE FORMA FRICCIONAL A UN ANILLO (26) DE LEVA COAXIAL A TRAVES DE RODILLOS (34) QUE SE SUJETAN EN SOPORTES (23) DE RODILLOS. PARA SIMPLIFICAR LA FABRICACION DE LA BOMBA DE INYECCION, EL EJE (11) DE ACCIONAMIENTO SE ASIENTA EN EL EJE (19) DISTRIBUIDOR CON UN CABEZAL (34) DE ACOPLAMIENTO SIMILAR A UNA COPA. UN NUMERO DE RANURAS (35) AXIALES QUE CORRESPONDE AL NUMERODE PERFORACIONES (20) RADIALES ESTA DISPUESTO EN LA PARED DE COPA PARA RECIBIR DE FORMA DESLIZANTE LOS SOPORTES (2) DE RODILLO. EL ACOPLAMIENTO SE ASEGURA POR MEDIO DE UN DISCO (37) DE ACOPLAMIENTO PROVISTO CON PROYECCIONES (371-374) DE ACOPLAMIENTO RADIAL, AJUSTADOS DE FORMA, QUE ENTRAN EN LAS RANURAS (35) AXIALES CON UN VACIADO (38) DENTRO DEL CUAL SE RECIBE UN APOYO (39) FRONTAL DEL EJE (19) DISTRIBUIDOR AJUSTADO DE FORMA (FIG.1).
