Abstract

The device (10) has an endless band (12) comprising sections (24) that are arranged in an end to end manner. A length varying unit varies lengths (L1, L2) of the sections. The endless band comprises two zones (Z1, Z2), and is pulled by a driving system i.e. roller (20), where one length (L1) of each section passing in one zone (Z1) is greater than another length (L2) of each section passing in another zone (Z2). A mobile piston is placed in a body of a cylinder. The variation unit comprises two slides.
