  • Pressure regulator baffle seat with radial flow paths
    Patent number: 6334460
    Abstract: A flow-through pressure regulator includes a housing having an inlet and an outlet offset along a longitudinal axis. The housing is separated by a divider into a first chamber and a second chamber. The divider has a passage that communicates the first chamber with the second chamber. The passage includes a first section extending along the longitudinal axis and a second section extending transverse to the longitudinal axis. A closure member permits or inhibits flow through the passage.

  • Fuel system including a pressure regulator
    Patent number: 6286486
    Abstract: A fuel system that comprises a tank, a pump, a flow-through pressure regulator, and piping connecting these components and an internal combustion engine. The flow-through pressure regulator can maintain a substantially constant noise output from low fuel flow rates to high fuel flow rates. Further, the pressure of fuel in the regulator at a maximum fuel flow rate can be made substantially equal to or less than the pressure of fuel in the regulator at a minimum fuel flow rate.
