  • Patent number: 8113446
    Abstract: An apparatus for controlling a flow of fluid in an emergency fixture is disclosed. The apparatus includes a body and a control element at least partially located in the body and configured to impart rotation into the fluid flow. The control element includes an inlet that receives the fluid flow. The control element also includes a first outlet portion configured to guide a first portion of the fluid flow out of the control element as an axial flow and a second outlet portion configured to provide rotation to a second portion of the fluid flow relative to the axial flow. The first portion of the fluid flow exits the control element at a position downstream from the position that the second portion of the fluid flow exits the control element.
    Type: Grant
