Abstract

The cam ring (14) is provided with an equal number of evenly spaced cams (15). The cams are located diametrically opposite to each other to move two plungers towards each other. The plungers are carried by a rotor (10) turned at one quarter engine speed. The plungers apply pressure to a fuel feed which is then passed to injector feed pipes (1a - 1e) as the rotor turns. The cam ring is also rotated at one quarter engine speed and in the opposite direction (B) which gives a fuel injection every 72 degrees of rotation.
