To facilitate adjusting the dashpot, the cross-section varying component is a plate-shaped slide ( ) provided with one or more breaches ( ) and traveling from side to side, preferably in a slot ( ), with its flat surface ( ) subjected to fluid from each cylinder chamber alternately by way of channels ( & ).
