Abstract: A steering system for an agricultural vehicle with a hydraulic steering motor incorporates an internal pump, a distribution valve, an input shaft which in use is coupled for rotation by the steering shaft of a vehicle steering wheel, and connectors for hydraulic lines leading to a high pressure source of oil, to an oil reservoir and to hydraulic actuators connected to the steerable wheels of the vehicle. The steering motor is located remotely from the steering shaft and is coupled for rotation with shaft by hydraulic rotary actuators mounted on the steering shaft and the input shaft of the steering motor and arranged in a closed circuit with one another.

Abstract: A gerotor pump has a pump body having a cavity for housing an outer rotor having an outer surface which slides on the surface of the cavity, and an inner surface with lobes projecting inwards of the outer rotor; and an inner rotor, which is fitted to a drive shaft having an axis of rotation, and has lobes which mesh with the lobes of the outer rotor. The inner rotor is divided into at least two lobed portions by cutting the inner rotor along a plane substantially perpendicular to the axis of rotation.
