Abstract

LA BOMBA DE INYECCION DE COMBUSTIBLE PRESENTA UN EMBOLO DE BOMBA (13) QUE TRABAJA EN UN TALADRO CILINDRICO (10), QUE SE ACCIONA POR MEDIO DE UN ACCIONAMIENTO DE LEVAS (14) EN UN MOVIMIENTO TANTO EN VAIVEN COMO TAMBIEN GIRATORIO. EL ACCIONAMIENTO DE LEVAS (14) CONSTA DE UN DISCO DE LEVA (17) GIRATORIO ACOPLADO CON UN EJE DE ACCIONAMIENTO (16) Y DE UN ANILLO DE RODILLOS (18) ESTACIONARIO, SOBRE CUYOS RODILLOS (20) SE APOYA EL DISCO DE LEVA. EL ANILLO DE RODILLOS (18) ESTA BLOQUEADO POR UN PERNO (30) QUE INCIDE EN ESTE QUE, POR OTRA PARTE, ESTA ALOJADO EN UN TALADRO RADIAL (32) EN UNA CORREDERA (33). LA CORREDERA (33) ESTA DISPUESTO DESPLAZABLE EN UNA RANURA LONGITUDINAL (36) EN LA PARTE INTERIOR DE LA CARCASA DE LA BOMBA (11) A LO LARGO DE SU EJE LONGITUDINAL, PERO TANGENCIAL AL ANILLO DE RODILLOS CON POCO JUEGO (18).THE FUEL INJECTION PUMP HAS A PUMP PUMP (13) THAT WORKS ON A CYLINDRICAL DRILL (10), WHICH IS OPERATED THROUGH A CAMERA DRIVE (14) IN A MOVEMENT BOTH IN SWING AND ALSO ROTATING. THE CAMS DRIVE (14) CONSISTS OF A ROTATING CAM DISC (17) COUPLED WITH A DRIVE SHAFT (16) AND OF A STATIONARY ROLLER RING (18), ON WHOSE ROLLERS (20) THE CAM DISC IS SUPPORTED. THE ROLLER RING (18) IS LOCKED BY A BOLT (30) THAT INCIDATES INTO THIS WHICH, OTHERWISE, IS LODGED IN A RADIAL DRILL (32) IN A SLIDER (33). THE SLIDE (33) IS ARRANGED IN A LONGITUDINAL SLOT (36) INSIDE THE PUMP HOUSING (11) ALONG ITS LONGITUDINAL SHAFT, BUT TANGENTIAL TO THE RING OF ROLLERS WITH LITTLE PLAY (18).
