Abstract: A steering system for vehicles with independent axles is disclosed. The system may have a second circuit for control of a second cylinder. The second circuit may have a solenoid valve, with at least four ways and three positions. The solenoid valve may be interposed between a second hydraulic liquid inlet line, a second hydraulic liquid outlet line, and a third operating duct and a fourth operating duct for the passage of hydraulic liquid. The system moreover envisages an electronic unit for management and control of the directional-control solenoid valve, which is operatively connected to a device for detecting the steering angle imposed by the first cylinder and is designed to manage the directional-control solenoid valve as a function of the data detected by the device.

Abstract: The gear pump may have a casing, a main shaft and rotating means connected to one end of the main shaft and configured to rotate the main shaft. Housed by the casing, a toothed wheel and at least one other toothed element are intermeshed with the toothed wheel. The other end of the main shaft is connected to one of the toothed wheel and the casing. Rotating the main shaft relative to the rotating means rotates the toothed wheel and the at least one other toothed element relative to the casing, thereby generating the flow. The other one of the casing and the toothed wheel is configured to be rotated around an axis defined by the main shaft for varying a flow rate of the generated flow.
