The invention relates to an adjustable seat post. A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes aremovable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. Asecond pressure chamber has a second pressure not proportional to the load. A flow path connects the first and second pressure chambers. A valve is disposed along the flow path and is configured to move between a closed position closing the flow path and an open position opening the flow path between the first and second pressure chambers. An isolator of the valve is configured to nullify any resultant force produced by the loaded pressure of the first pressure chamber acting on the isolator.

    本发明涉及一种可调节座杆。用于自行车的座杆组件具有:具有第一远端的第一管;以及具有第二远端的第二管。所述第一管与所述第二管能相对于彼此移动以沿管轴线在所述第一远端与所述第二远端之间建立间隙。第一压力室具有与沿所述管轴线施加的负载成比例的负载压力。第二压力室具有不与所述负载成比例的第二压力。流路连接所述第一压力室与所述第二压力室。阀沿所述流路布置,并且构造成在封闭位于所述第一压力室与所述第二压力室之间的所述流路的封闭位置与打开所述流路的开放位置之间移动。所述阀的隔离器构造成使由所述第一压力室的作用在所述隔离器上的所述负载压力产生的任何合力抵消。
