Flow through fuel pressure regulator |
摘要 |
<p>A flow-through type fuel pressure regulator (30) having, for its valve element, a sphere (70) laser-welded to the housing end wall (50) of the fuel inlet chamber (56), and for its valve seat (68), a coined circular surface circumscribing a through-passage (66) in an annular member (60) at the center of a movable wall (diaphragm) (54) that divides the fuel inlet chamber from the fuel outlet chamber (58) and that is resiliently biased toward the fuel inlet chamber by a spring (82) that is disposed in the fuel outlet chamber. The annular member includes a series of circumferentially spaced bars (114) 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. <MATH></p> |
