Abstract

I en koplingsanordning (1,2) som skal benyttes i et omgivende miljø med høyt trykk og eventuelt aggressivt eller skadelig omgivende fluidum, sikres en tetning (12) mot trykk fra det omgivende mediet ved tilveie- bringelse av tilsvarende trykk fra baksiden. Det er derfor i et grensesnitt- område mellom de innbyrdes roterbare delene (1, 2) av koplingen tilveiebrakt et kammer (18) for et hydraulisk fluid, for eksempel olje, og dette hydrauliske fluidet gis tilsvarende trykk som omgivelsene via en membran (13) som utgjør et skille i et delt kammer (14,16) hvor indre del (14) er i kommunikasjon med det oljefylte kammeret (18), og ytre del (16) er i kommunikasjon med det omgivende miljø via en åpning (15).In a coupling device (1,2) to be used in a high pressure ambient environment and possibly aggressive or harmful ambient fluid, a seal (12) is secured against pressure from the surrounding medium by providing corresponding pressure from the rear. Therefore, in a interface region between the mutually rotatable portions (1, 2) of the coupling, a chamber (18) is provided for a hydraulic fluid, for example oil, and this hydraulic fluid is given the same pressure as the surroundings via a membrane (13). which forms a separation in a divided chamber (14, 16), wherein the inner part (14) is in communication with the oil-filled chamber (18), and the outer part (16) is in communication with the surrounding environment via an opening (15).
