Abstract
A valve vane is provided, where the valve vane is movable along the surface of a casing part and is driven by a dog follower, guided in a slot of the casing part, wherein the slot is furnished at least at one end, and wherein a flat slider is required for a sealing of the casing part. Such a flat slider requires by itself a substantial structure. The invention valve vane (6) is structured such that it covers the slot (12) in each phase of its motion. The invention structure is particularly suitable for being employed in a inlety valve system of a compressor.
