Claims (3)
1. A rotary hydraulic valve to control the hydraulic pressure in power steering gears for automotive vehicles, comprising: an input-shaft; a coaxially arranged driven member; a torsion bar drivingly connecting said input-shaft and said driven member, interengaging means connecting said input-shaft and said driven member irranged for limited lost motion between said input-shaft and driven member; an axially movable sleeve surrounding said 0 o input-shaft; an intermediate member carried between said sleeve and said driven member to provide a slack-free driving connection between said sleeve and said driven member; the said intermediate member being in the form of a thin arcuately shaped member having arms, extending partially around and embracing the driven member and outwardly and inwardly extending lugs respectively ongaging and fitting closely within slots formed in the sleeve and the driven member, the lug fitting within the slot in the sleeve being constructed and arranged to permit axial movement of the sleeve.
2. A rotary hydraulic valve as claimed in Claim 1 wherein the arms of the intermediate member fit closely within a circumferential groove formed on the driven member.
3. A rotary hydraulic valve substantially as described with reference to and as illustrated in the accompanying drawings. DATED THIS 13 DAY OF May 1988. A.E.BISHOP ASSOCIATES PTY.LIMITED Patent Attorneys for the Applicant F.B.RICE CO.
