Abstract

A regulable hydraulic dashpot for motor vehicles and including a cylinder (1) filled with hydraulic fluid and a piston (2) that is attached to the end of a piston rod (7), travels back and forth inside the cylinder, and divides it into two chambers (3 & 4) that communicate through at least one bypass. The bypass's cross-section can be varied in size by a component that is, preferably continuously, controlled by a motor or magnet. To facilitate adjusting the dashpot, the cross-section varying component is a plate-shaped slide (23) provided with one or more breaches (25) and traveling from side to side, preferably in a slot (24), with its flat surface (27) subjected to fluid from each cylinder chamber alternately by way of channels (14, 15, & 16).
