Abstract (en)

[origin: EP2075398A2] The drive (10) has a housing (11) i.e. cylindrical tube, comprising a fluid volume in a closed system, where volume change of hydraulic fluids (20) due to heat expansion is compensated by a gas volume subjected by the fluids. The compensated gas volume is enclosed by a tube section and a bellow. Pressure of the hydraulic fluids acts on a mantel surface of the tube section and the bellow. The tube section and the bellow are made of flexible, rubber elastic material. The tube section and the bellow are held by a fixed compensation container.
