Air suction device

The device has a storage vessel and partly flexible intake pipes leading to the cylinders. The pipes have rigid or length-variable sections, and these are divided into two or more independently moveable segments (13,14). The segments are held in a common pivot point (15), or are longitudinally moveable. Each segment has coupling points (18) with radial and/or axial seals. The first segment (16) is flanged to a cylinder head and is rigid, the second segment is turnable/sliding, the third element is rigid.
