Abstract

A pressure-actuated valve which includes an effective pressure face by which the valve is opened, the face on which the pressure difference that opens the valve acts is completely independent of an openable flow opening. The effective pressure face and the openable flow opening can be selected arbitrarily within wide limits, independently of one another. The pressure-actuated valve according to the invention is preferably suitable for shock absorbers.
