A shuttle-type metering device for controlling a liquid fuel supply to an internal combustion engine has a pair of shuttles slidable within a rotor and defining three chambers in the rotor, three ports in the rotor open into the respective chambers. A stationary sleeve surrounds the rotor and has three rows of ports with which the rotor ports respectively and successively communicate as the rotor rotates. Each row of sleeve ports has an even number of ports which are alternately arranged as inlet and outlet ports. The porting arrangement is arranged to supply fuel to an engine having an odd number of cylinders. |
