Abstract:
1. A hydrostatic power steering device comprising a source of pressurized fluid, a cylindrical distributor ( 100 , 200 ) an outer barrel and an inner spindle of which are connected elastically together, the spindle ( 200 ), 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 ( 400 ) 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 chambers ( 301 ′, 302 ′) of a hydraulic actuator ( 800 ) connected to the steering wheel, characterised by comprising an auxiliary feed conduit ( at least one slide valve ( a barrel locking system ( holes and grooves in the outer barrel and in the spindle to directly connect said auxiliary feed conduit to one or other of the chambers (
