Abstract

Offenbart ist eine Steueranordnung für mehrere Verbraucher, wobei jedem Verbraucheranschluss eine Zumessblende (26,28) und ein Senkbremsventil (30,32) zugeordnet ist. Zumindest eine zulaufseitige Zumessblende steht in Wirkverbindung mit einer Individualdruckwaage (34,90). In dem Fall, in dem jeder Zumessblende eine Individualdruckwaage zugeordnet ist, können diese in eine einzige Druckwaageneinheit integriert sein.
