Patent number: 6052900Abstract: A power steering control valve (22) has an inner valve member (40) which is connected with a follow-up member (54) by a torsion bar (102). An outer valve member (42) is fixedly connected with the follow-up member (54) by indentations (56). Before the outer valve member (42) is fixedly connected with the follow-up member (54) by the indentations (56), the inner and outer valve members (40 and 42) are moved relative to each other to determine a hydraulically centered condition. When the power steering control valve (22) is in the hydraulically centered condition, equal fluid pressures are conducted to a power steering motor (31) in response to equal clockwise or counterclockwise actuation of the valve members (40 and 42) relative to each other. The outer valve member (42) is then fixedly connected with the follow-up member (54) with the power steering control valve (22) in the hydraulically centered condition.Type: GrantFiled: June 22, 1998Date of Patent: April 25, 2000Assignee: TRW Inc.Inventor: Christopher T.
