    • An improved power steering device which has a pinion shaft connected with a steering wheel, a rack rod which is connected with steerable wheels and whose rack is in mesh with the pinion of the pinion shaft in the gear box, a power cylinder for hydraulically actuating the rack rod, and a changeover valve for selectively connecting the first and second hydraulic chambers of the power cylinder with the hydraulic pressure source and the oil reservoir. The pinion shaft is rotatably supported in the oscillating cage which is rotatably mounted on the gear box in a manner such that the axis of the oscillating cage is offset a certain distance from the axis of the pinion shaft, whereby the oscillating cage rotates about its axis when the steering torque is applied to the pinion shaft. The oscillating cage is connected with the changeover valve so that the latter is actuated by the rotary movement of the oscillating cage. With this construction, the changeover valve can be made to respond accurately to the steering torque and at the same time it is possible to reduce the size and simplify the structure of the device.

    • A power steering apparatus including a reaction control valve operable to be opened by a force proportional to a speed of a vehicle, and to be closed under a pressure in a reaction chamber. The pressure of a source of hydraulic pressure or a pressure proportional to the pressure of the hydraulic pressure source is applied so as to open the reaction control valve even when the vehicle speed exceeds a predetermined value. Thus, a steering reactive force, which would otherwise be limited at the predetermined speed of the vehicle, is controlled so as to be proportional at a proper ratio to a resistance from a road as it increases, thereby assuring more accurate steering of a vehicle.

    • In a vehicle which is provided with a power steering device having an oil passage or an oil chamber whose pressure increases to a high level as a steering angle becomes large; and a damper device consisting of a cylinder filled therein with a working oil and a piston fitted slidably in the cylinder to divide the interior thereof into upper and lower oil chambers, the damper device being adapted to damp the relative movements of a chassis and a wheel support member, the damper device is characterized in that it is provided with a variable throttle mechanism interposed between the upper and lower oil chambers and operable to increase its degree of restriction in proportion to the rise of pressure in the oil passage or oil chamber of the power steering device. This simply constructed device is obtained at a low cost and enables the damping force to vary continuously without use of sensors and processor.

    • The hydraulic power steering system comprises a rotary valve unit actuated according to a twisting angle provided in a torsion bar connected between an input shaft and a pinion, and a conversion mechanism which can change the condition of the rotary valve unit for a given twisting angle of the torsion bar. A variable ratio lever mechanism may be used for this purpose. Thus, a torsion bar having a suitable rigidity can be used without causing any insufficiency in the assisting torque because the responsiveness of the steering system can be freely varied by changing the setting of the conversion mechanism. For instance, it is possible to provide a sufficient assist torque at low speed and a controlled responsiveness at high speed.
