A vehicle ride strut includes a piston 143, which reciprocates in a cylinder 20 to divide the cylinder into two compartments 146, 148, flow of liquid between compartments on a contraction stroke in the operating range being less restricted than flow on an extension stroke in the operating range, which is in turn less restricted than flow on extreme extension. The piston is formed with passages 160 provided with check valves 158 and also with constricted passages 174. A valve member 180, formed with narrow passages 194 leading to an annular groove 196 adjacent the piston 143, engages the piston 143 upon extreme strut extension to greatly diminish flow of liquid through the piston 143. <IMAGE> |
