摘要:
The present invention relates to high speed control valves which are especially applicable for use in fuel injection systems. Producing a valve with a quick response time within acceptable packaging constraints and with a structure that allows the valve to be mass produced with consistent performance between valves is extremely problematic. By moving flow restrictions within the valve away from the valve seats, flow forces on the valve member can be reduced, while possibly also permitting a reduction in the necessary travel distance of the valve member to improve response time and other performance characteristics. The valve is particularly applicable in controlling hydraulic pressure applied to the closing hydraulic surface of a direct control needle valve in a fuel injector.
摘要(中):
本发明涉及特别适用于燃料喷射系统的高速控制阀。 在可接受的包装限制内产生具有快速响应时间的阀门,并且具有允许阀门在阀门之间具有一致性能的批量生产的结构是非常有问题的。 通过将阀内的流动限制移动离开阀座,可以减小阀构件上的流动力,同时还可以减小阀构件的必要的行进距离以改善响应时间和其他性能特征。 该阀特别适用于控制施加到燃料喷射器中的直接控制针阀的关闭液压表面的液压。
