    摘要： An internal pulse damper for use in a fuel rail for an internal combustion engine. The damper is formed from a length of tubular metal stock having a flat oval cross-section and ends flattened by crimping to form a captive-air pillow. The end crimps are improved through use of tooling to eliminate a creased sidewall area vulnerable to stress failure in prior art pulse dampers. Such tooling includes constraints to prevent the tubing sides from flaring out and forming a longitudinal crease adjacent the end crimp during squeezing-shut of the tube end.

    摘要： A fluid pulse damper having increased dynamic range and sensitivity, being especially useful in suppressing pulsations in the fuel supply rail of an internal combustion engine. The damper is a longitudinal gas-filled plastic pillow having walls formed by opposed flexible short sides and opposed flexible long sides, and includes at least one internal self-contact element, and preferably a plurality of such elements. As the short sides flex, the elements make contact internally, shifting the damper into a different compression regime and extending the pressure/response over an increased range of pressures. A feature of some embodiments is that the inner surface within the contact elements is shifted into tension after the elements make contact, thereby stiffening the damper and increasing the damper's resistance to further deformation. The damper is formed of a plastic such as ultra-high molecular weight polyethylenes, high flow polyetherimides, or tubing grade polyphthalamides.

    摘要： An internal pulse damper for a fuel rail. The damper has an increased captive air volume and consequent improved damping and stress characteristics. The improved damper is a pillow having a modified flat oval cross-sectional profile, with two long diaphragm sides and rigid short sides connecting the two long sides. At least one of the short sides, and preferably both, is strengthened by being provided with a longitudinal reverse bend or inwardly-extending longitudinal rib generally parallel with the long sides. Preferably, the short sides are somewhat higher than the comparable short sides of similar prior art dampers, to increase the captive air volume, yet are not high enough to preclude installation of the improved damper within an existing fuel rail configuration.

    摘要： A fuel pressure regulator including a valve head having a centerline offset from the centerline of a corresponding fuel orifice. The valve head may be offset with respect to the valve seat and orifice, the orifice may be offset within the seat with respect to the head and diaphragm assembly, or the axes of the head and seat may be non-coaxially biased. Because the vector of the valve closing force does not align with the centerline of the valve head and diaphragm assembly, a resulting torque on the valve head keeps the head in a stable, pivoted position at all flow rates. The valve head always makes contact with the valve seat at a predetermined point during regulator operation, eliminating pressure instabilities and noise experienced in prior art pressure regulators.
