ABSTRACT:
A correction device in a vehicle power steering apparatus adapted to effectively utilize the aiding effect of a hydraulic power cylinder depending upon travelling speeds of the vehicle. A change in value of rightward or leftward acceleration resulted from the turning of the vehicle is sensed by a weight oscillatably received within a closed oil chamber of the correction device to allow the operator to perceive an adequate steering resistance, thereby avoiding his erroneous steering. The correction device includes stoppers positioned at tip surfaces of nozzle members to provide a desired clearance between an end surface of a pressure restriction plate and the nozzle member thus allowing oil in the nozzle to flow. The device further includes compression springs retained between the weight and the casing for biasing the weight towards its neutral position, the compression spring engaging an adjusting screw to predetermine a value of lateral acceleration of the vehicle.
