Abstract
A bypass valve assembly includes an outer casing and a spaced outer liner defining an annular bypass channel for channeling bypass air. The outer liner includes a plurality of circumferentially spaced slots around which are positioned an annular valve body. The valve body is positionable from a closed position substantially blocking bypass airflow into the slots to an open position uncovering the slots. Positioning means rotates and translates the valve body over the outer liner for covering and uncovering the slots.
