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.

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.

Abstract: A flow-through pressure regulator includes a retainer that secures a diaphragm relative to a seat, and includes a cylindrical portion, an axial end portion and an annular portion. The cylindrical portion extends about a longitudinal axis and is fixed with respect to the seat. The axial end portion extends from the cylindrical portion and extends generally orthogonal relative to the longitudinal axis. The axial end portion includes a plurality of apertures that permit fluid communication and are selected so as to reduce noise due to fluid flow.

Abstract: A pressure regulator includes a housing, a divider including a first valve member, and a second valve member. The housing includes an inlet and an outlet, and defines an interior volume. The divider separates the interior volume into first and second chambers, and included the first valve member, a diaphragm, and a retainer. The diaphragm extends between the housing and the first valve member. Fluid communication between the first and second chambers through the diaphragm being prevented. The retainer secures the diaphragm relative to the first valve member, and the retainer is press-fitted with respect to the first valve member. The second valve member is arranged between first and second configurations relative to the first valve member. The first configuration substantially prevents fluid communication between the inlet and the outlet, and the second configuration permits fluid communication between the inlet and the outlet.

Abstract: A flow-through pressure regulator includes a divider, a closure member and a housing. The divider separates a first chamber from a second chamber, and includes a passage that provides fluid communication between the first and second chambers. The closure member moves relative to the divider between first and second configurations. The first configuration substantially prevents fluid communication through the passage, and the second configuration permits fluid communication through the passage. The housing includes a first homogeneous housing portion and a second housing portion. The first homogeneous housing portion includes an inlet, defines the first chamber, and forms a pocket that receives a majority of the closure member. The second housing portion includes an outlet and defines the second chamber.

Abstract: A pressure regulator includes a housing, a divider, and a valve. The housing includes an inlet and an outlet. The divider separates the housing into a first chamber and a second chamber. And the valve includes a spherical valve ball and a seat. The spherical valve ball is fixed with respect to a first one of the housing and the divider, and the seat is fixed with respect to a second one of the housing and the divider. A first configuration of the spherical valve ball with respect to the seat substantially prevents fluid communication between the inlet and the outlet, and a second configuration of the spherical valve ball with respect to the seat permits fluid communication between the inlet and the outlet.

Abstract: A tool is provided for removing a component from a fuel rail in an automotive fuel system. The tool has a pair of jaws connected to a pair of pivoting handles, which allow the jaws to be opened and closed. The jaws have an inner cavity shaped to conform to an outer surface of the component. A pair of release members are slidably mounted on an outer surface of the jaws. When the release members are moved relative to the jaws, rims on the release members contact a retention clip holding the component to the fuel rail. Contact between the rims and the clip causes the clip to disengage from a retention surface on the fuel rail, freeing the component.
