摘要： A torque shaft assembly includes a hollow tube with a central axis disposed between and fixedly connected to first and second crankshafts at first and second distal ends, respectively, of the tube for movement of an array of connecting members such as push rods. A hollow interior of tube between the first and second crankshafts is filled with a sufficient quantity of flowable inertia material or damping media to absorb vibratory energy by friction during operation of the engine. The hollow interior is preferably filled with a quantity of damping media to a level by volume of about 98% and a preferred flowable inertia material is round steel shot. A plurality of spaced-apart clevises are fixedly attached to a tube wall on an outer surface of the tube wall surrounding the hollow interior. Each clevis includes connection means disposed away from the wall outer surface for connection with an actuator for movement of the array of adjustable devices such as variable stator vanes.

摘要： 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.
