Abstract
A fuel injection pumping apparatus of the rotary distributor type has a distributor member rotatable within an angularly adjustable sleeve carried in the body of the apparatus. The sleeve is coupled to an angularly adjustable cam ring having internal lobes operable to impart pumping movement to a plunger carried in a bore in the distributor member. The distributor member has a delivery passage connected to the bore for registration with outlets in turn to the sleeve. The distributor member also has a further and restricted passage which registers with the outlet which has just received fuel for the purpose of absorbing pressure waves which may be reflected back to the outlet from the associated injection nozzle. The fact that the sleeve and cam ring are connected to each other means that as timing variation is effected by moving the cam ring angularly the phasing between the outlets, the delivery passage and the further passage remains constant.
