摘要： A hydraulic reaction force apparatus for a power steering system includes input and output shafts, a flange, balls, a reaction force receiving portion, a hydraulic reaction force chamber, and an annular reaction force piston. The input and output shafts are accommodated in a body. The flange is formed on one of the input and output shafts and has axial through guide holes. The balls are movably fitted in the guide holes, respectively. The reaction force receiving portion is formed on the other one of the input and output shafts to axially receive the balls. The hydraulic reaction force chamber is formed at a position opposite to the reaction force receiving force receiving portion with respect to the flange. The reaction force piston is movably and coaxially fitted on the output shaft with a clearance to urge the balls against the reaction force receiving portion so as to generate a restriction force corresponding to a reaction force oil pressure. The restriction force acts between the input and output shafts. Seal rings are disposed between the reaction force piston and the body and between the reaction force piston and the one of the input and ouput shafts.

摘要： A steering force controller for power steering apparatus is disclosed, which controls an oil pressure supplied to an oil pressure reaction chamber in accordance with a position of a spool valve which is caused to be displaced fore and aft in accordance with a vehicle speed. The spool valve is slidably fitted into a sleeve which is in turn disposed within a bore formed in a housing. The oil pressure supplied to the oil pressure reaction chamber can be controlled in accordance with the displaced position of the spool valve with respect to the sleeve. A regulating member is provided for causing an axial displacement of the sleeve, thus facilitating a regulation of a relative position between the spool valve and the sleeve.
