Abstract

1300679 Power steering NISSAN MOTOR CO Ltd 12 May 1971 [1 June 1970 (2) 11 Aug 1970] 14425/71 Heading B7H A vehicle has an hydraulic power steering system in which the vehicle’s road speed is used to modulate the reaction pressure in the reaction chamber 15 of the control valve 11 by means of a modulator valve 13 placed between the fluid pump 10 and the reaction chamber 15. The control valve 11 is incorporated in the steering linkwork and comprises a spool 28 having grooves 45, 46 which works in a valve body 16 to which is connected the steering pump P at bore 40 and the power steering ram at bores 47, 48. The “feel” at the steering wheel is due to the pressure in the reaction chamber 15 acting on a spring seat 32 which is slidable inside spool 28 and which acts on the steering wheel via rod 38. Pump P communicates with the reaction chamber 15 via the pressure modulator valve 13 which may be, as shown in Fig. 2, of the nozzle-flapper type wherein a torque motor 54 fed by a D.C. current generated in proportion to vehicle speed controls the spacing X between the flapper 52 and the nozzle 51. Alternatively the modulator valve 13 may comprise a chamber having an inlet from pump P, an outlet to the valve 11 and a further orifice variable controlled by a poppet valve operated by a solenoid also fed by a speed dependent D.C. current. In a further modification (Fig. 6) a valve 75 attached to propeller shaft 76 contains a spool 83 which slides outwards at high shaft speed to increase flow from bore 80 to urge spool 92 of valve 77 to the right, thus increasing pressure in line 102 which leads to control valve 11.
