Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur fluidischen Umschaltung, wobei die Zeit verkürzt zur Umschaltung des Fluids verkürzt wird. Dazu dient ein Drei-Wege-Ventil (8), das mit weiteren Anschlüssen zur Pumpe (4) versehen ist und der Schieber (2) eine entsprechende konstruktive Gestaltung erfährt. Mit Hilfe der Anschlüsse und zusätzlicher Druckspeicher im Schieber wird eine entsprechende Druckkraft gespeichert, die während des Umschaltvorganges, wenn die Anschlüsse zum fluidischen System und zum Vorratsbehälter verschlossen sind, dazu dient, der Bewegung des Schiebers zeitversetzt eine weitere Bewegung, die vom auf dem Schieber angeordneten Schiebering (16) ausgeführt wird, zu überlagem.
