POWER STEERING VALVES

摘要

A hydraulic valve for a power steering gear comprising a sleeve journalled on an input-shaft (2). The sleeve having a torsion bar (1) connected thereto via a driven member, the input-shaft having an axially extending bore (6). The torsion bar (1) having an axially extending bore (4) in a fixing end thereof, the fixing end being remote from the driven member and located within the bore (6) of the input-shaft. The surface of the input-shaft bore (6) and the outer surface of the fixing end of the torsion bar (1) forming an interface therebetween. At least one diametral member (5) is press-fitted within the axial bore of the torsion bar and a keying formation (7) is disposed on at least a portion of one or both surfaces forming said interface. In a second embodiment two diametral members (5) are press-fitted within the axial bore (4).
