ABSTRACT:
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.
