Abstract

Et stempel, frem- og tilbakebevegelig i en sylinder, er avtettet mot sylinderveggen ved hjelp av fluid av et trykk som er høyere enn trykket av fluidene på de motsatte sider av stempelet, som fremføres til ringrommet (18) mellom to tetninger (19,20) som er virksomme mellom stempelet og sylinderveggen, og hvor det er anordnet en akkumulator eller et hjelpeforsterkerkammer (67) hvorfra overtrykksfluid overføres til ringrommet mellom de to tet- ninger, for regulering av trykket mellom disse. De to tet- ninger mellom stempelet og sylinderveggen kan bestå av henholdsvis første (19A-19C) og andre (20A-20C) grupper eller antall av separate tetningsringer som, vedrørende materialet og dimensjoner, er utvalgt for gjennomføring av spesielle funksjoner. Videre kan et tetningssystem mellom et stempel og en sylinder hvori stempelet er frem- og til- bakebevegelig, omfatte en fremre tetning (19,20), fortrinnsvis med to tetninger eller tetningsring-grupper som beskrevet, som atskiller et prosess- eller drivfluid (4) som holdes i bevegelse av stempelet, fra et andre fluid (7) i ringrommet rundt stempelet, og en atskilt og baken- forliggende sperretetning (21A-21C) atskiller det andre fluid fra et tredje fluid som fyller et ytterhus (6) med en innmontert motor for drift av stempelet.
