Variable-length exhaust for a two-stroke internal combustion engine

摘要

Device allowing a variable exhaust length. This principle is characterised by a bore 4 in which slides a sphere 1 equipped with a sealing ring 2. This device allows the curve 3 to penetrate into the bore 4 and this being with the curve 3 misaligned with respect to the bore 4 by several degrees. <IMAGE>
