Abstract

Anordnung zur Regelung von Druck und/oder Volumenstrom eines hydraulischen Antriebselementes (Z1), insbesondere eines Arbeitszylinders. Der dem Antriebselement (Z1) von einer Pumpe (P) zugeführte Volumenstrom ist mittels einer Steuer-und/oder Regeleinrichtung (V1) einstellbar, wobei zusätzlich ein Druckspeicher (DS) und eine mittels einer elektrischen oder elektronischen Steuereinrichtung (B) aktivierbare hydraulische Regeleinrichtung (A) vorgesehen sind. Die Regeleinrichtung (A) umfasst mehrere Einrichtungen (A1, A2, A3, A4). Die erste Einrichtung (A1) zur Beeinflussung von Druck und/oder Volumenstrom des Antriebselementes (Z1) umfasst ein Rückschlagventil (RSV), ein Regelventil (RV1) und mindestens einen Drucksensor (PS1). Die zweite Einrichtung (A2) zur Umleitung von Hydraulikflüssigkeit von der Regeleinrichtung (A) zur Steuer- und/oder Regeleinrichtung (V1) ist mit einem Mehrwegeventil (MV) gebildet ist. Die dritte Einrichtung (A3) zur Erfassung eines momentan eingestellten Betriebszustandes am Antriebselement (Z1) umfasst mindestens einen Drucksensor (PS3) und ein Ventil (V3). Die vierte Einrichtung (A4) zum Trennen oder Verbinden von Steuer- und/oder Regeleinrichtung (V1) und Antriebselement (Z1) ist mit einem Regelventil (RV4), insbesondere einem Proportionalventil, gebildet.
