A pressure limiting valve having a housing head and a housing jacket. An axial inlet opening in a valve base is axially separated from an outlet opening. An inner valve seat connects to the inlet opening and an axially mobile valve piston is arranged to produce a closing force against a pressure (p) acting at the inlet opening. The valve body is formed as a stepped piston with a first step having a first surface that is acted upon in the axial direction by the pressure. The stepped piston has a first axial length that defines a first peripheral throttling gap with an inner surface (of the valve seat. The stepped piston also has a second step with a second surface that may be acted upon in the axial direction by the pressure, and together with the first surface (A1), forms a total pressure surface. The second step has a second axial length (L2) that defines a second peripheral throttling gap. |
