摘要： A fluid injection valve includes a fluid inlet tube with a recess and a valve body including a central longitudinal axis. The valve body includes a cavity with a fluid outlet portion. The injection valve also includes a valve needle received in the recess and in the cavity. The valve needle is axially displaceable with respect to the fluid inlet tube and the valve body for preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in other positions. The injection valve includes a spring element arranged in the recess and operable to interact with the valve needle for biasing the valve needle in axial direction towards its closing position, wherein the spring element is configured such that a spring stiffness of the spring element depends on a pressure of fluid in the recess.
摘要翻译：流体注射阀包括具有凹部的流体入口管和包括中心纵向轴线的阀体。阀体包括具有流体出口部分的空腔。喷射阀还包括容纳在凹部中和腔体中的阀针。阀针相对于流体入口管和阀体可轴向移动，用于防止流体在关闭位置流过流体出口部分，并在其它位置释放通过流体出口部分的流体流。注射阀包括布置在凹部中并可操作以与阀针相互作用的弹簧元件，用于将阀针沿轴向朝向其关闭位置偏置，其中弹簧元件构造成使得弹簧元件的弹簧刚度取决于凹槽内流体的压力。
