    • A flow through pressure regulator apparatus and method for directing a flow of fuel within a fuel system. Present invention includes a lower housing having a fuel inlet where fuel flows through the fuel inlet and communicates with a valve biasing member through a fuel chamber and lower valve element with fuel passages. The valve biasing member permits or inhibits fuel flow through a fuel chamber by opening and closing a ceramic valve element. The valve biasing member comprises a flat disk having at least two reticulated concentric rings coupled by at least one bridge. The fuel flows past an open valve element through the lower valve element fuel passages to the valve biasing member. The valve biasing member then diffuses the flow of fuel. A fuel cover directs the flow of fuel from the valve biasing member to the fuel outlet.
    • 一种用于在燃料系统内引导燃料流的压力调节装置和方法。 本发明包括具有燃料入口的下部壳体,其中燃料流过燃料入口并且通过燃料室和具有燃料通道的下部阀元件与阀偏压构件连通。 阀偏压构件通过打开和关闭陶瓷阀元件来允许或阻止通过燃料室的燃料流动。 阀偏压构件包括具有至少两个通过至少一个桥连接的网状同心环的平盘。 燃料通过打开的阀元件通过下阀元件燃料通道流向阀偏压构件。 然后阀偏压构件扩散燃料流。 燃料盖将来自阀偏压构件的燃料流引导到燃料出口。
