Abstract: A linear actuator for linear actuation of a process valve which has a housing is disclosed. An electronic control unit, at least one electric drive unit, and at least one hydraulic drive are located in the housing. The hydraulic drive includes at least one hydraulic cylinder with a piston and a piston rod. The piston rod extends outwardly through an opening in the housing. The hydraulic drive is configured to convert an electric drive power of the electric drive unit into a hydraulic driving force which generates a linear movement of the at least one hydraulic cylinder in a first direction. A linear movement of the piston of the hydraulic cylinder in a second direction opposite to the first direction is generated by a restoring force on the piston rod, which restoring force acts on the piston rod outside the housing.

Abstract: A system filled with a fluid, designed for underwater applications, in which the interior of a housing and/or tank forms a fluid region which is sealed with respect to the surrounding seawater region, includes at least one hydraulic pressure compensation device, which at least raises the pressure level of the fluid region to the ambient pressure prevailing in the seawater region. The pressure compensation device is constructed in two stages in such a way that at least one store having a flexible wall region and at least one piston store having a displaceable piston are arranged in series. The use of the pressure compensation device to pressurize at least one housing filled with fluid for a hydraulic actuating shaft is also proposed.

Abstract: An electrohydraulic system includes an output shaft, a hydraulic piston, and a preload device. The output shaft rotationally drives the valve and extends along a first axis. The hydraulic piston extends along a second axis perpendicular to the first axis, is actuated by a pressure medium, and rotates the output shaft. The preload device stores energy via preloading of an elastic element, which extends along a third axis, by a hydraulic cylinder and to transmit the energy to the output shaft in the event of a fault. The hydraulic piston is guided into first and second cylinder housings, and at least one of the cylinder housings is connected to the hydraulic cylinder. A check valve is arranged between the cylinder housing and the hydraulic cylinder, and is configured to decouple the preload device from the hydraulic piston, the blocking direction going from the hydraulic cylinder to the cylinder housing.

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.

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.

Abstract: A method is for controlling a subsea system including at least one slave subsea electronic module installed in a subsea device, to prevent brownout of the subsea system. The system includes a master subsea electronic module, configured to provide power to the at least one slave subsea electronic module. The subsea device is configured to execute several operations. The method includes measuring the voltage or the current provided from the subsea electronic module to the slave subsea electronic module, and comparing the measured voltage or current value with a threshold value. When the measured voltage is lower than the threshold value or the measured current is higher than the threshold value, the method powers off or limits a power of at least one of several components of the subsea device which is used to execute one of the several operations using the slave subsea electronic module.

Abstract: An electrohydraulic system having an adjustment device for a valve includes a drive apparatus, a control apparatus, and a preloading apparatus. In the event of a fault, the energy stored in the preloading apparatus can be transferred to the control apparatus such that a rotational motion of the control apparatus begins, which leads to the adjustment of the valve. The preloading apparatus comprises at least one elastic element, which is arranged adjacent to a control shaft of the control apparatus, is stationarily connected to the control shaft, and applies a torque to the control shaft.
