PURPOSE:To make up a small sized device by linking an air metering valve and a fuel metering valve of a slide type spool valve with those valve bodies parallelly arranged. CONSTITUTION:An air metering valve 5 provided in the upstream of a throttle valve 3 in an intake air manifold 2 is controlled by a negative pressure actuator 11 operated by suction pressure. A fuel metering valve 17 or a slidable spool valve in a valve case 20 having an inlet port 18 at one end and outlet 19 at the other is formed in the way of a fuel circuit 8 supplying a fuel injection nozzle with fuel in a fuel tank 6 by a pump 7. A valve case 20 extending in the sliding direction of the valve is put in parallel with a valve case 9 of the air metering valve 5. A lever 22 in contact with a cam 21 around on a turning rod 10 of the valve 5, tracing the profile of the cam 21, provides the fuel metering valve 17 with the behaviour of metering the fuel quantity required. |
