Abstract

Anordning og fremgangsmåte ved sirkuleringsventil for. en aktuator (1) som forsynes med trykkfluid via en retningsventil (10) og et første forbindelsesrør (A) til et første trykkfluidkammer (4) respektive et andre forbindelsesrør (B) til et andre trykkfluidkammer (8), idet tilførsel av trykkfluid til ett av trykkfluidkammerne (4, 8) bevirker at aktuatorens (1) virksomme organ (6) forskyves mot en korresponderende endestilling, og hvor en av det virksomme organ (6) styrt forbipasseringsventil (12, 14) kommuniserbart er koplet mellom forbindelsesrørene (A, B), idet forbipasseringsventilen (12,14) er innrettet til automatisk å åpne en forbindelse mellom forbindelsesrørene (A, B) når det virksomme organ (6) befinner seg i en bestemt stilling.
