Abstract:
1. A device for guiding at least two flow media having different pressures, comprising a shaft or similar force-transmitting member and a pressure-insulating element surrounding the shaft or similar, characterized in that areas ( 90 , 90 a ; 96 ; 98 ) which lie next to one another in the direction of the axis are defined between the force-transmitting member ( 10 ) and the pressure-insulating element by sealing elements ( 70 , 70 a ), wherein at least one of the sealing elements ( 70 , 70 a ) is designed to be leakage-free and two areas ( 90 , 90 a , 98 ) for fluids (A, B) having different pressures flank an area ( 96 ) for an auxiliary liquid (H), and a conveying device ( 100 ) for subdividing the latter area ( 96 ) into two partial areas ( 96 a , 96 b ) defining two different pressure regions, the conveying device ( 100 ) is arranged within the partial areas for generating a pressure difference between the partial areas ( 96 a , 96 b ).
