Abstract
A regulating unit for accomplishing a linear movement includes a cylindrical frame part () having a cylinder part () and cylinder head (), which define a piston space (), and a piston unit () to be moved by a pressurized medium in the piston space. The height of a first space (), in which a piston part () is moveable, is bigger than the height of a piston part, the cross section area is bigger than a cross section area of a piston rod. A cross section area of a second space () is smaller that the cross section area of the piston part. Pressurized medium may be fed into a cavity space (), which is between the facing surfaces of the piston part and the piston space, for moving the piston unit towards the cylinder head () or vice versa.
