Abstract

An electrohydraulic system for use at great water depths includes a vessel, a hydrostatic machine, and an electric machine. The vessel has an interior space configured to form a volume that is closed off with respect to the surroundings and that accommodates a hydraulic pressure fluid. The vessel includes a compensation piston configured to subject the hydraulic pressure fluid in the interior space to at least approximately the pressure prevailing in the surroundings. The hydrostatic machine is configured to be operated as a pump. The electric machine is mechanically coupled to the hydrostatic machine and operates as an electric motor in order to operate the hydrostatic machine as a pump. The hydrostatic machine and the electric machine are arranged in the interior space of the vessel. The compact electrohydraulic system fits on existing installations and on new installations. The electrohydraulic system also includes a compact process valve.
