Abstract
A dashpot piston in halves, the face of each resting against that of the other. The piston can be fastened to the end of a piston rod either directly or by way of a connector. Each half ( & ) is provided with a depression ( ) along the circumference remote from the face of the other, creating a continuous groove ( ) with a shorter diameter and accommodating a piston-assembly ring ( ). Manufacture is facilitated by the inclusion of at least one resilient supporting ring ( ) between the piston-assembly ring and the base of the groove.
