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).
