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.Device and method for circulation valve for. an actuator (1) which is supplied with pressure fluid via a directional valve (10) and a first connection pipe (A) to a first pressure fluid chamber (4) and a second connection pipe (B) to a second pressure fluid chamber (8), respectively, the supply of pressure fluid to one of the pressure fluid chambers (4, 8) causes the actuator's (1) active member (6) to be displaced towards a corresponding end position, and where one of the active member (6) controlled by-pass valves (12, 14) is communicatively connected between the connecting pipes (A, B ), the bypass valve (12,14) being arranged to automatically open a connection between the connecting pipes (A, B) when the active member (6) is in a certain position.
