Abstract

Eine Ventilbaugruppe für die Ansteuerung wenigstens eines Verbrauchers umfasst zwei verbraucherseitige Anschlüsse (A, B), einen Pumpen- und einen Tankanschluss (P, T) sowie vier über jeweils einen Steueranschluss (c1-c4) hydraulisch angesteuerte Steuerkanten (C1-C4), von denen eine erste (C1) den Pumpenanschluss (P) und den ersten verbraucherseitigen Anschluss (A), die zweite (C2) den Pumpenanschluss und den zweiten verbraucherseitigen Anschluss (B), die dritte (C3) den ersten verbraucherseitigen Anschluss (A) und den Tankanschluss (T) und die vierte (C4) den zweiten verbraucherseitigen Anschluss (B) und den Tankanschluss (T) verbindet. Zwei Vorsteuerventile (Y1, Y2) sind zum Ansteuern der Steueranschlüsse (c1-c4) von je zwei der Steuerkanten (C1-C4) vorgesehen.
