An O-ring engages the internal surface of the sleeve and the external surface of the fitting and allows the valve to be rotated relative to the connector without breaking the sealing engagement between the valve and the connector.

  • Multi-adaptive fuel pressure regulator
    Patent number: 4653528
    Abstract: A fuel pressure regulator has a multi-faceted extruded base that allows the outlet from the pressure regulator to be oriented in any of six different directions. A fuel body has a projecting snout and a fuel passage extending through the snout, and the inlet to the pressure regulator plugs directly onto the snout; the fuel passage thereby supplies fuel to the pressure regulator, and the pressure regulator thereby maintains the desired fuel pressure in the passage.
