Distributor Fuel Injection Pumps - DPA (Lucas) Type. This pump uses a single steel rotor, which works as the pumping element and also distributes the fuel. The rotor rotates in a stationary steel cylindrical sleeve known as the hydraulic head.

The pumping section of the rotor is flanged and has a larger diameter than the distributor section. It has a transverse cylinder bore to house two opp

osed pumping plungers. A stationary internal-cam ring is installed in the pump housing and operates the plungers through rollers and shoes, which are placed in slots machined into the circumference of the rotor flange. The cam ring uses as many lobes as there are engine cylinders, and they are evenly placed round the ring. The outward movement of the opposed plungers is controlled by metered fuel pressure.
