摘要： A stepped rotation fuel distribution valve for receiving and conducting metered, pressurized fuel pulses to the combustion cylinders of a diesel engine is provided. The valve includes a fuel distribution shaft rotatably mounted in a valve housing. The shaft includes a fuel discharge port that is sequentially registrable with fuel distributing passages in the housing that ultimately lead to the diesel fuel injectors associated with the combustion cylinders of the engine. A drive mechanism, which may include a stepper motor, intermittently rotates the fuel distributor shaft so that the shaft discharge port dwells in registration with one of the fuel distributing passages at the time a pressurized pulse of fuel is discharged through the shaft discharge port. The drive mechanism may also include either a set of timing gears or a spring coupling to achieve the desired intermittent rotation. In all cases, the intermittent rotation of the fuel distribution shaft prevents the shaft from rotating at a time when the discharge of a highly pressurized fuel pulse applies a high side load to the shaft which in turn can generate high frictional forces between the fuel distribution shaft and the surrounding housing.
