ABSTRACT:
A rotary distributor fuel injection apparatus comprises a distributor rotor (3) having a fuel inlet port (c) and delivery port (d) which communicates in turn with successive ports (g) supplying individual cylinders. The rotor (3) has a central axial passage (b) connected to the ports (c) and (d) and a radially drilled port (e) which aligns succesively with ports (h), radially drilled in the sleeve (13), whose rotation is controlled by a helical groove (i) on a thrust sleeve (14) through a peg (17) located on the sleeve (14). Centrifugal governor weights (15) and (16) control the position of the sleeve (14) and thereby the instant at which the port (e) communicates with a port (h) to terminate injection.
