Claim 0:
1. Hydraulic system for controlling an angle of attack and/or a pivoting out and in of a stabilizer wing comprising:
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;
a first hydraulic circuit having:
a low-pressure circuit and a high-pressure circuit;
a device for providing an admission pressure of the low-pressure circuit;
two anti-cavitation valves separating the low-pressure circuit from the high-pressure circuit;
a first hydraulic pump driven by an electric motor and having two connections integrated in the high-pressure circuit and hydraulically connected to the rotary vane motor and/or the hydraulic cylinder;
the two connections of the first hydraulic pump each fluidically connected to a first line, wherein the first line is fluidically connected to the rotary vane motor and/or the hydraulic cylinder; and
the two connections of the first hydraulic pump each fluidically connected via a check valve to the first line.
