An assembly for a hydraulic dashpot. The dashpot is accommodated in an overall housing () and provided with a shock-absorbing piston () traveling back and forth inside the housing on one end of a piston rod () and partitioning the housing into two compartments (&), and a vibration-compensating piston () hydraulically paralleling the first piston and accommodated inside a subsidiary housing (). The object of is to ensure a solid and reliable connection between the shock-absorbing piston and the piston rod while allowing as much of the piston rod as possible to find support inside the housing. The vibration-compensating piston is accordingly an annular piston and travels back and forth with its inner surface resting against a section () of the piston rod adjacent to the fastening for the shock-absorbing piston, and with its outer surface against the inner surface of the subsidiary housing.

Assembly for a Hydraulic Dashpot

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.
