  • Patent number: 11117669
    Abstract: A vane assembly for distribution of a stratified fluid in an aircraft is taught herein. The vane assembly includes a housing including a housing inlet and a housing outlet. The housing inlet is configured to receive the stratified fluid with the stratified fluid including a first portion and a second portion. The housing outlet is configured to exhaust the stratified fluid. The housing defines an interior housing volume between the housing inlet and the housing outlet. The vane assembly further includes a vane disposed within the interior housing volume and bisecting the interior housing volume. The vane includes a leading edge adjacent the housing inlet and a trailing edge adjacent the housing outlet. The trailing edge is angularly offset from the leading edge.

  • Publication number: 20050194458
    Abstract: A valve subassembly of a fuel injector that allows spray targeting and distribution of fuel to be configured using non-angled or straight orifice having an axis parallel to a longitudinal axis of the subassembly. Metering orifices are located about the longitudinal axis and defining a first virtual circle greater than a second virtual circle defined by a projection of the sealing surface onto the metering disc so that all of the metering orifices are disposed outside the second virtual circle. The projection of the sealing surface converges at a virtual apex disposed within the metering disc. At least one channel extends between a first end and second end. The first end is disposed at a first radius from the longitudinal axis and spaced at a first distance from the metering disc.

  • 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.
