fluid volume 358 flows from a first side 366 of the dual piston valve 360 to a second side 368 of the dual piston valve 360 during an event causing the shock absorber 350 to rebound a portion of the vehicle attached to the mounting element 352 moves upward thereby releasing the downward pressure that is forcing the mounting element 352 downward and or pulling the mounting element 352 upwards the damping fluid cylinder 356 moves out of the gas cylinder 354 as the dual piston valve 360 moves closer to the top of the damping fluid cylinder 356 further as the dual piston valve 360 moves further to the top of the damping fluid cylinder 356 the fluid that had previously flowed to the second side 368 during the event causing the shock absorber 350 to compress now flows from the second side 368 to the first side 366 embodiments enable the low speed rebound fluid flow to be adjusted independently of the high speed compression fluid flow and the high speed rebound fluid flow to be adjusted independently of the high speed compression fluid flow fig6 a is an enlarged sectional side elevation view of section b of fig3 b illustrating fluid pathway aa in regard to low speed rebound fluid flow in accordance with an embodiment with reference to fig4 a and 6a the low speed and the high speed rebound fluid flow rate may be adjusted by adjusting the rebound adjust rod 302 such that the taper.
