Abstract

A damper includes at least one substantially longitudinal damping body with two end surfaces and one substantially longitudinal surface between. The damping body is placed in a substantially longitudinal cavity, which includes a cavity surface, with a damping fluid that includes a liquid and a gas. At least one of the cavity surface, end surfaces or longitudinal surface is broken, and the damping body can pulsate in the cavity when the damper is in operation.
