Vorrichtung nach Anspruch 7, wobei der Kommunikationsdurchgang zwei Endkanäle (343) umfasst, die in den Endkolben (33) ausgebildet sind, und einen zentralen Kanal (340), der axial in der zentralen Verbindungsstange (34) zwischen den zwei Endkolben (33) ausgebildet ist, wobei die Endkanäle (343) die jeweiligen Arbeitskammern (300) und den zentralen Kanal (340) in Fluidkommunikation versetzen.
  9. Vorrichtung nach Anspruch 8, wobei der zentrale Kanal (340) die zwei Endkolben (33) von einer Seite zur anderen durchquert, wobei die Dämpfungsschalter (31) dimensioniert sind, um die jeweiligen mündenden Enden (341) des zentralen Kanals (340) zu verschließen, und wobei die Endkanäle (343) die Form von Rillen aufweisen, die auf den Seiten am Ende der jeweiligen Endkolben (33) eingearbeitet sind und die jeweiligen Arbeitskammern (300) und die jeweiligen mündenden Enden (341) des zentralen Kanals (340) in Fluidkommunikation versetzen.
  10. Vorrichtung nach Anspruch 9, wobei die Rillen (343) eine allgemeine Spiralform aufweisen, die geeignet ist, um eine Verengung beim Fließen des Fluids zwischen den jeweiligen Arbeitskammern (300) und dem zentralen Kanal (340) zu bilden.
  11. Vorrichtung nach einem der Ansprüche 8 bis 10, wobei der zentrale Kanal (340) innen mit zwei antagonistischen Düsen (342) ausgerüstet ist, die ausgebildet sind, um Lastverluste im Fluidfluss im zentralen Kanal (340) zu erzeugen.
  12. Vorrichtung nach einem der Ansprüche 7 bis 11, wobei der Verteilungsschieber (32) zwei Übergangskolben (35) umfasst, die im Dämpfungshohlraum (30) gleiten und um die zentrale Stange (34) zwischen den Endkolben (33) derart angeordnet sind, dass der Verteilungsschieber (32) innen drei innere Kammern mit konstantem Volumen begrenzt, nämlich zwei seitliche innere Kammern (321), die zwischen den Endkolben (33) und den benachbarten Übergangskolben (35) angeordnet sind, und eine zentrale innere Kammer, die zwischen den zwei Übergangskolben (35) angeordnet ist.
