Abstract
An accumulator type fuel injector system including an arrangement for insuring that the injector will provide a relatively constant rate of fuel discharge under low speed low load conditions and a rate of discharge under high speed high load conditions that reaches its peak at the latter portion of the injection valve opening cycle. This is done by changing the effective areas of the various components of the valve, the preload of the biasing spring and the rate of the biasing spring.
