Abstract
Disclosed is a damping device to be incorporated into fluid systems, particularly hydraulic systems, said damping device comprising an expansion hose. An essentially rigid damper which is oriented counter to the direction of flow, is disposed inside the internal space of said expansion hose. The damper pipe is provided with a completely closed wall, resulting in a good damping effect. Preferably, the damper pipe is significantly less flexible in the radial direction than the outer expansion pipe, whereby the damping effect is substantially enhanced.
Claims19
A damping device for a fluid system, comprising:
- a damper housing which encloses an internal space and has an input connection, as well as an opposing output connection, and
- a damper pipe which has a closed wall and, starting from the output connection, extends into said internal space, wherein the damper pipe contains a support structure.
