Abstract

Ein Ventil (1) umfassend: ein Ventilgehäuse (3) mit mehreren Fluidanschlüssen (A, P, T), die zumindest einen Versorgungsanschluss (P) und zumindest einen Nutzanschluss (A) umfassen, einen im Ventilgehäuse (3) verfahrbaren Steuerkolben (11) zur Ansteuerung der Fluidanschlüsse (A, P, T) und eine verschiedene Steuerzustände für den Steuerkolben (11) einnehmende Betätigungseinrichtung (13), ist dadurch gekennzeichnet, dass zumindest in einem Steuerzustand der Betätigungseinrichtung (13) mittels einer Druckbegrenzungseinrichtung (31) der Ausgangsdruck (p_Aktuator) im Nutzanschluss (A) dem sich ändernden Eingangsdruck (p_Eingang) im Versorgungsanschluss (P) auf ein vorgebbares Druckniveau (p, p') nachfolgt.
