ABSTRACT:
A fluid control valve unit particularly suited to be used as an air control valve in an overhead passenger service unit for aircraft, buses, trains and the like. This valve unit includes a non-rotatable and axially movable closure member which moves in response to rotation of an axially non-movable actuator member supported in a universally pivotable and tiltable housing. This valve has relatively few component parts and is thus easy to manufacture and assemble. A helical groove on the actuator member cooperates in a cam-like manner with a projection on the closure member to create the desired translation.
