<p>A cylinder/pump unit, operated by a pressure medium in which a drive motor (18) is arranged, preferably axially, on an axial housing wall (7) which contains, preferably axially, a pressure-medium pump (12, 13), a control valve system (10), a pressure-medium storage and balancing volume (32), as well as a working piston (18) with a working piston rod (40). The pressure medium pumping pressure thus makes it possible to have at least one stroke direction for the working pump. In a solution offered by the invention the drive-motor shaft (15) for actuating the control valve system is supported in an axially displaceable manner; in another solution the valve actuation is carried out by a mechanical transmission system via the hollow drive shaft. In yet a further solution proposed by the invention, at least one axial pressure medium line is provided, for example as a pipe (8, 3) running axially in an off-centre position, arranged in the cylinder pipe in such a manner that the at least one pressure medium line in a sealed manner passes through fluid volumes (23, 24, 32) of the component and at least the working piston (18). Other axial appropriately arranged pressure medium lines are provided according to the design, whereby preferably one axial pressure medium line connects the cylinder base (22) to the cylinder cover (4).</p> |
