Abstract
The invention concerns a pressure reduction valve () with a housing (), a valve element () being displaceable in the housing and acted upon in one direction by a pressure in a low-pressure chamber connected with an outlet () and in the opposite direction by the force of a spring (), which is arranged in a spring chamber () in the housing (). It is endeavoured to improve the dynamic behaviour of the pressure reduction valve. For this purpose, a pilot flow path () connects the low-pressure chamber () and the spring chamber () with each other.
