ABSTRACT:
A flow through pressure regulator apparatus and method for directing a flow of fuel and reducing valve seat wear within a fuel system. Present invention includes a lower housing having fuel inlet where fuel flows through the fuel inlet and communicates with a valve assembly and valve biasing member. The valve assembly comprises a lower and upper valve member where the lower valve element contains a plurality of fuel passages. The valve biasing member permits or inhibits fuel flow through the lower valve member by opening and closing an upper valve member. 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 upper valve member through the plurality of fuel passages that encircle the lower valve member 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.
