ABSTRACT:
A high-pressure viscous damper is proposed, in particular for use in liquid chromatographs, in which two chambers are separated by an elastic partition, and the one chamber receives a fluid to be damped and the other chamber holds a damping fluid. In the chamber holding the damping fluid an insert is provided within the fluid with a selected volume and temperature expansion coefficient so that by the combination of the insert and damping fluid and the volume and wall material of the second chamber a volume compensation is achieved.
