  • Hydrostatic power steering device for fast steering
    Patent number: 6863147
    Abstract: Hydrostatic power steering device comprising a source of pressurized fluid, a cylindrical barrel-type distributor the elements of which are connected elastically together, and of which the inner element, the so called spindle, is connected to the steering wheel; the distributor being arranged to assume a central position, the so-called neutral position, in which it directly short-circuits, to discharge, the fluid originating from the source of pressurized fluid, and two positions, symmetrical about the central position, in which the distributor, via a dispenser of orbital type the rotor of which is rigidly connected to the steering wheel shaft and to the spindle, feeds the fluid to one and respectively to the other of the chambers of a hydraulic actuator connected to the steering wheel; the device also comprises an auxiliary conduit for feeding the pressurized fluid to the cylindrical distributor; a slide valve operable by the driver to feed said auxiliary feed conduit when desired; a barrel locking system op
