Abstract
The hydraulic system according to the invention is a hydraulic system for controlling a stabilizer drive, in particular for controlling an angle of attack and/or a pivoting out and in of a stabilizer wing, preferably for ships. The hydraulic system according to the invention has a rotary vane motor that changes the angle of attack of the stabilizer wing and/or a hydraulic cylinder for pivoting the stabilizer wing out and in, along with a first hydraulic circuit. The first hydraulic circuit furthermore comprises a low-pressure circuit and a high-pressure circuit, a device for providing an admission pressure of the low-pressure circuit, and two anti-cavitation valves which separate the first low-pressure circuit from the first high-pressure circuit. The hydraulic system according to the invention is furthermore characterized in that a first hydraulic pump driven by an electric motor and having two connections is integrated in the high-pressure circuit.
