PURPOSE:To make it possible to conveniently perform the control of fuel supply at a low cost but a high degree of accuracy, by using a plurality of valves of a simple structure which are automatically opened by fuel pressure, and as well by controlling the distribution of fuel to these valves. CONSTITUTION:When an engine E runs, a rotor 6 rotates so that fuel is distributed to automatic valves 4 through ports 5a through 5d at suitable timing. When the fuel thus distributed is fed to the automatic valves 4, the automatic valves 4 are successively opened by fuel pressure, and therefore, supply the fuel, successively to the branch pipe sections 1a through 1d of a manifold 1. When the operating condition of the engine varies, a step motor is suitably driven in accordance with control pulse signals from a computer so that the rotational speed of the rotor 6 is modulated, to rotate at a multiplied speed. With this arrangement the valve-opening time of the rotor varies, thereby the distributing amount of fuel is controlled in accordance with the operating condition of the engine. |
