Abstract

Anordning for strømningsregulering, omfattende en ytre hylse (13) som har i det minste en åpning (14) gjennom veggen, en indre hylse (15) som har i det minste en åpning (16) gjennom veggen og midler for å bevirke innbyrdes glidebevegelse av hylsene (13, 15) mellom åpne stillinger som muliggjør variabel strømning av fluid gjennom åpningene (14, 16) i hylsene (13, 15), og lukkede stillinger, og et tetningsarrangement (17, 18, 19) mellom den indre (15) og ytre hylsen (13), omfattende i det minste én tetning (18), og som kjennetegnes ved midler for tetnings-bypass anordnet for å muliggjøre at en del av fluidet siver rundt tetningen (18) slik at fluidtrykket som virker mot et område av tetningen (18) minskes.
