Abstract
A piston for a hydraulic dashpot. The piston () is mounted on one end of a piston rod (), travels back and forth inside a cylinder (), which it divides into two chambers (&), and has a body () provided with axial channels (&), each of which can be opened and closed at the end by a one-way valve in the form of a cup spring or stack of cup springs (&), independently adjusting their tensions for both the compression and the suction phases. The cup springs (&) rest against and in alignment with the body, and the tension is adjusted by deforming the body resiliently or plasticly against its contact surface.
