Abstract
A hydraulic system, for use under water with a hydraulic actuating drive, includes a hydraulic cylinder and at least one hydraulic machine. At least one rotary drive device and the hydraulic machine are coupled mechanically for a common rotating movement, and the hydraulic machine adjusts at least the hydraulic cylinder. The hydraulic cylinder has at least three cylinder chambers, and the hydraulic system includes a first hydraulic circuit and a second hydraulic circuit. The hydraulic system for use under water is set up, in particular, with a redundant hydraulic actuating drive for manual (mechanical) actuation.
Claims13
A hydraulic system for use under water, comprising:
- a hydraulic cylinder having at least three cylinder chambers;
- at least one hydraulic machine configured to adjust the hydraulic cylinder;
- a first hydraulic circuit that includes at least one first cylinder chamber of the at least three cylinder chambers;
- a second hydraulic circuit hydraulically separate from the first hydraulic circuit, the second hydraulic circuit including at least two second cylinder chambers of the at least three cylinder chambers;
- a container defining an interior in which the hydraulic cylinder and the at least one hydraulic machine are arranged;
- an interface having a portion that is external to the container, the interface being operably connected to the at least one hydraulic machine;
- and
- a remote-controlled underwater vehicle having a first rotary drive device configured to be selectively coupled to and decoupled from the at least one hydraulic machine via the external portion of the interface such that the first rotary drive device drives the at least one hydraulic machine when coupled to the at least one hydraulic machine.
An apparatus configured to be arranged underwater and to control a volumetric flow conveyed of a gaseous or liquid medium, comprising:
- a process valve that includes a process valve housing and a process valve slide by way of which the volumetric flow is controlled;
- and
- a hydraulic system comprising:
- a hydraulic cylinder assigned to the process valve, the hydraulic cylinder having at least three cylinder chambers, the hydraulic cylinder being configured to move the process valve slide;
- at least one hydraulic machine configured to adjust the hydraulic cylinder;
- a first hydraulic circuit that includes at least one first cylinder chamber of the at least three cylinder chambers;
- and
- a second hydraulic circuit hydraulically separate from the first hydraulic circuit, the second hydraulic including at least two second cylinder chambers of the at least three cylinder chambers;
- a container defining an interior in which the hydraulic cylinder and the at least one hydraulic machine are arranged;
- an interface having a portion that is external to the container, the interface being operably connected to the at least one hydraulic machine;
- and
- a remote-controlled underwater vehicle having a first rotary drive device configured to be selectively coupled to and decoupled from the at least one hydraulic machine via the external portion of the interface such that the first rotary drive device drives the at least one hydraulic machine when coupled to the at least one hydraulic machine.
