Embodiment Construction

[0028] The piston-cylinder assembly shown in these figures has a cylinder 1, which is closed at its ends by a first closing part 14 and a second closing part 15, in which a piston 2 is arranged axially displaceable. . The piston 2 divides the liquid-filled interior of the cylinder 1 into a first working chamber 3 and a second working chamber 4 .

[0029] Arranged on one side of the piston 2 is a piston rod 5 , which extends coaxially through the second working chamber 4 and is guided outwards via the guide and seal 6 and the second closure 15 .

[0030] The piston rod 5 has a continuous axial passage 7 in which an actuating rod 8 is axially displaceably guided. Arranged at the outer end of the actuating rod 8 protruding from the piston rod 5 is an actuating device 9 by means of which the actuating rod 8 can be directly or indirectly driven axially displaceably.

[0031] In the region of the end of the first working chamber 3 opposite the piston rod 5 , a stop piston part 10 ...

Abstract

The invention relates to a piston-cylinder assembly which includes a cylinder 1 having a cylinder interior filled with a fluid and divided by a piston 2, which is axially displaceable in the cylinder1, into a first working space 3 and a second working space 4. A piston rod is arranged on piston and is guided through second working space 4 and through an end-side second closure 15 in a manner sealed off to the outside at the second end of the cylinder. The retraction stroke of piston 2 and piston rod 5 is restricted by a stop which is arranged in cylinder 1 and against which piston 2 comes tobear directly or indirectly, wherein the axial position of the stop in cylinder 1 is variably adjustable by an adjustment device.

Description

technical field [0001] The invention relates to a combined piston-cylinder device with a cylinder, which is filled with a liquid and whose cylinder interior is divided into a first working chamber and a second working chamber by a piston axially displaceable in the cylinder, the piston The cylinder assembly has a piston rod arranged on the piston, which passes through the second working chamber and is guided sealingly outward by a second end-side closure at the second end of the cylinder. Background technique [0002] In a piston-cylinder combination of this type, only the moved-in end position and the moved-out end position are reproducible positions, but not the intermediate positions. Although the lockable piston-cylinder assembly can also be positioned in an intermediate position between the moved-in end position and the extended end position, this intermediate position cannot be reproduced. Contents of the invention [0003] It is therefore the object of the present ...
