A resilient leg as part of an attachment for the wheel of a motor vehicle. The leg is provided with a piston rod ( ) that has a piston ( ) attached to it, that travels into and out of a housing ( ), that is attached at its outer end to the vehicle's chassis, and that is maintained in radial alignment by two separated bearings. The piston divides the interior of the housing into two fluid-charged chambers ( & ). The object is to ensure satisfactory transmission of moments of force from the piston rod to the housing in a leg that is light in weight. The piston rod accordingly extends through, and is maintained in radial alignment at, both ends of the leg.

Resilient leg

A hydraulic dashpot with a cylinder ( ) full of shock-absorbing fluid, with a piston ( ) mounted on the end of piston rod ( ), traveling back and forth inside the cylinder, separating the cylinder into two compartments ( & ), and provided with ports and shock-absorption valves, and with a variable bypass system accommodated in an axial bore ( ) in the piston rod provided with lateral radial openings ( & ) extending through the rod. The object is to allow fixed independent establishment of the cross-section of the bypass system available for the fluid to flow through as the piston rod travels in the direction associated with the suction phase and of the cross-section of the bypass system available for the fluid to flow through as the piston rod travels in the direction associated with the compression phase. The bypass system is accordingly provided with an axially moving control tube ( ) whereof one end comes to rest against one valve assembly ( ) and the other end comes to rest against another valve assembly ( ) and whereby its axial motion is limited by stops.
