A hydrostatic cylinder with a gas pressure accumulator, which is preferably designed as a piston accumulator, and which is arranged concentrically on the outer circumference of the cylinder is disclosed. A gas pressure is produced via a constant pressure source and is limited or is essentially constant in the gas pressure accumulator and also a constant pressure medium pressure is independent of the degree of filling of the gas pressure accumulator.

Hydrostatic cylinder with gas pressure accumulator

A hydraulic control block for controlling a supply of pressurizing medium to an electrohydraulic or servo hydraulic axle includes a plurality of internally situated hydraulic interfaces configured to fluidically connect at least one of a source of pressurizing medium and a pressurizing medium sink of the axle to any hydraulic cylinder selected from a group of hydraulic cylinders of different structural forms, wherein the internally situated hydraulic interfaces are configured to selectively supply pressurizing medium to the selected hydraulic cylinder. The control block further includes an insert part configured as a function of the structural form of the selected hydraulic cylinder such that each of the plurality of internally situated hydraulic interfaces is one of tapped and blocked for the purpose of the fluidic connection.

Hydraulic control block and hydraulic axle therewith

An electrohydraulic system for use under water includes an electrohydraulic actuator and a container having an internal space provided for forming a volume which is enclosed from the environment and which is provided for receiving a hydraulic pressurized fluid. A hydraulic cylinder is provided in the internal space of the container, the inside of which is divided into a first cylinder chamber and a second cylinder chamber by a piston to which a first piston rod and a second piston rod are connected. The two active surfaces of the piston are the same or approximately the same size.
