  • Fuel injector and fuel rail check valves
    Patent number: 6830034
    Abstract: A fuel injector with a neck at an upstream end and a downstream end located at a distal end from the upstream end, a fuel channel extending from the upstream end to the downstream end and defining a substantially longitudinal axis, and a check valve located in the fuel channel proximate the upstream end; and a fuel rail with a housing defining an opening having a substantially longitudinal axis passing therethrough, and a one-way flow inhibitor is located in the opening. When removing the fuel injector from the fuel rail, reducing leaks by biasing a plunger of the check valve against a seat of the check valve in the fuel injector and biasing a plunger of the one-way flow inhibitor against a seat of the one-way flow inhibitor in the fuel rail.
    Type: Grant

  • Clip retention of a split-stream fuel injector to a fuel rail cup including circumferential locator
    Patent number: 5035224
    Abstract: The cup into which the injector inlet is inserted has a radial key on its lip which requires that the retention clip have a proper circumferential orientation for registration with the key in order to permit the full assembly of the injector to the cup to be achieved when the injector, with the clip attached thereto, is inserted into the cup. The key is formed during the cup fabrication process out of metal that would otherwise be a part of the offal stock that is trimmed from the perimeter of the blank after the blank has been drawn to form the cup.
