When the tube 10 is moved upwards under the action of the crankshaft 43, the spring sleeve 14 moves with it and compresses the weaker spring set in the chamber 26 Damped chamber 26. This damping is less than that produced by the liquid on the downstroke. As soon as the tube begins to move upward, the energy stored in the compressed lower springs creates an upward pressure when the pressurization of these springs is removed. This pressure is in addition to the action of the movement of the crankshaft and is sufficient to cause the entire stand device to jump forward.
