Fuel injection pumping apparatus

摘要

A fuel pumping apparatus includes a rotary distributor member including bores locating pump plungers. The plungers are engaged by shoes carrying rollers. An actuating member has a leading flank and a trailing flank and is movable along a path parallel to a tangent to the bore containing the distributor member. The leading flank is movable into the path of the rollers to impart inward movement to the rollers and the associated plungers. The position of the actuating member is adjustable to determine the amount of fuel pumped by the plungers.
