Fig. 4. The sequence of shuttle
movements in a twin-shuttle metering distributor to serve three cylinders.
The diagrams
illustrate inlet and outlet port connections each 120 degrees rotation of the
rotor.
It will be clear that a single shuttle arrangement as in Fig. 3 could not be
used to feed an odd number of cylinders,
and Fig. 4 shows how two shuttles operating between three ports can be used to
meet the requirements of a three-
cylinder engine.
By incorporating two bores in the rotor, with suitable arrangements of shuttles
and fuel inlet and outlet ports.
metering distributors operating on the basic principles described can be
designed to cater for four, six and eight cylinder
engines.
