Document Type and Number:
Japanese Patent JP2823678
Kind Code:

Abstract:
According to an illustrative example of the present invention a hydropneumatic positioning device comprises a tubular container. A hollow piston rod is guided through one end of the tubular container. A piston is connected with the piston rod within a cavity of the tubular container. The piston divides the cavity into two working chambers. The working chambers contain a liquid. Adjacent one of the working chambers, namely the working chamber remote from the piston rod, a compensating chamber is provided. This compensating chamber contains a pressurized gas and is separated from the adjacent working chamber by a floating separating wall. A flow passage extends through the piston between the two working chambers. A valve is allocated to the flow passage. The valve can be opened by an actuating rod extending through an axial bore of the hollow piston rod. The actuating rod extends beyond an outer end of the piston rod. An actuating signal transformer is fastened to the outer end of the piston rod. The signal transformer is constructed as a hydraulic press with a liquid chamber or as an electromagnetic coil with an armature, an input piston, and an output piston. The output piston acts onto the outer end of the actuating rod and the input piston can be actuated manually.
