Abstract
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.
