Abstract

The pressure spring is esp. for rail vehicles, and comprises a hollow cylindrical body (1) of rubber or similar material. The chamber inside it is closed at both ends (2, 3) and filled with fluid (4). The fluid can contain a gas or vapour bubble, and there can be metal rings (5) embedded in the body, in planes parallel to the end faces. Their internal diameter can be greater than that of the body, which can have sealing lips (8, 9) at both end faces.
