摘要： A steering system (10) for a vehicle (16) comprises a housing (20) having first and second end portions (32, 34) and an intermediate portion (50)- A steering member (66) is supported for axial movement in the housing (20)- A piston (100) fixed for movement with the steering member (66) has opposite end faces (104, 106). First and second springs (130, 132) engage the end faces (104, 106) of the piston (100) and bias the piston and thereby the steering member (66) in first and second axial directions toward a straight ahead position. Steering linkage (124, 126) connected with the piston member (100) transmits movement of the piston member (100) to steerable wheels (12, 14) of the vehicle.

摘要： A damper valve (70) located in a hydraulic power-assisted steering system (10) comprises a housing (72) having axially opposite first and second end portions (76, 78) and an intermediate portion (80) therebetween. The first end portion (76) communicates with the control valve (18) and the second end portion (78) communicates with the power steering motor (22). A flow restricting element (114) is movable through portions of the housing (72) including the intermediate portion (80) by fluid flow. A biasing element (106) restrains movement of the flow restricting element (114) toward the first end portion (76) of the housing (72). An orifice (116) formed between the flow restricting element (114) and the housing (72) restricts fluid flow greater than a predermined amount through the housing (72) from the second end portion (78) toward the first end portion (76).
