Monotube damper valve

摘要

A monotube damper valve is provided in a piston (14) with a piston body (26) having an annular bearing (42) and an extension stop surface (52). A piston rod (20) is connected to the piston body. A retainer (39) having a compression stop surface (51) is carried about the piston rod adjacent the piston body. A bearing washing (38) is carried about the piston rod near the retainer. A bi-directional monodisc valve element (40) has an inner perimeter (47) supported by the bearing washer and an outer perimeter (48) supported by the annular bearing in an at-rest condition. During a compression stroke of the piston body, the monodisc valve element is movable to a maximum compression deflected position wherein it is uniformly supported by the compression stop surface. During an extension stroke of the piston body the monodisc valve element is movable to a maximum extension deflected position wherein it is uniformly supported by the extension stop surface. <IMAGE>
