The invention relates to a height adjustable seatpost for a bicycle. An exemplary height adjustable seating post includes an upper tube and a lower tube configured in a telescopic arrangement and a piston in the upper tube. The piston divides the upper tube into a first chamber and a second chamber. The first chamber and the second chamber are filled with a fluid. The height adjustable seatpost also includes a valve including a fixed member and a rotatable member that form a face seal between a first face of the fixed member and a second face of the rotatable member. The stationary member has a fluid flow passage. The rotatable member is rotatable relative to the fixed member between a closed position, in which the rotatable member blocks the fluid flow passage to prevent fluid flow between the first chamber and the second chamber, and an open position, in which fluid is allowed to flow between the first chamber and the second chamber through the fluid flow passage.
本发明涉及用于自行车的高度可调节座杆。示例性高度可调节座杆包括以伸缩布置方式配置的上管和下管以及在上管中的活塞。活塞将上管分成第一腔室和第二腔室。第一腔室和第二腔室填充有流体。高度可调节座杆还包括阀,该阀包括固定构件和可旋转构件,它们在固定构件的第一面和可旋转构件的第二面之间形成面密封。固定构件具有流体流动通路。可旋转构件可相对于固定构件在关闭位置和打开位置之间旋转,在关闭位置,可旋转构件阻挡流体流动通路以防止流体在第一腔室和第二腔室之间流动,在打开位置,允许流体通过流体流动通路在第一腔室和第二腔室之间流动。
