ABSTRACT:
A flow-through type fuel pressure regulator having, for its valve element, a sphere laser-welded to the housing end wall of the fuel inlet chamber, and for its valve seat, a coined circular surface circumscribing a through-passage in an annular member at the center of a movable wall (diaphragm) that divides the fuel inlet chamber from the fuel outlet chamber and that is resiliently biased toward the fuel inlet chamber by a spring that is disposed in the fuel outlet chamber. The annular member includes a series of circumferentially spaced bars that form a cage for the sphere, allowing the sphere to guide the motion of the central region of the movable wall relative to the sphere substantially along the axis of the housing.
