Abstract
1484942 Power steering devices ADWEST ENG Ltd 3 Nov 1975 [2 Aug 1974] 34204/74 Heading B7H Power assisted rack and pinion steering gear includes means for reducing the power assistance at the end of the steering stroke. A piston 5 within cylinder 6 is mounted on rod 4 integral with a rack (1) (Fig. 1A, not shown) meshing with a pinion (3). A control valve connected to the pinion and steering control member directs fluid flow to either side of the piston 5 through port 11 or 12, the other port being connected to exhaust. Axially spaced from each port 12, 11 is a respect relief port 13, 15, port 12 connecting port 13 through passage 14 and port 11 connecting port 15 through annular passage 16. When piston 5 approaches its end stroke position it comes between ports 13 and 12 or between ports 15 and 11 so that fluid at the high pressure side of the piston may be exhausted. The piston is returned by the return action of the steerable wheels and the steering linkage. Pressure fluid supplied to return the piston is supplied to both sides of the piston since the relief ports are in communication with the supply ports, however, the relief ports, or passages thereto are restricted relative to the supply ports thus affording some assistance to the return action.
