Patent ID: 6921079

Claim:
A hydraulic seal arrangement between two shafts rotating relatively to each other, comprising: an annulus connected to a radially outer of the two shafts extending radially outwards on its circumference; a fin connected to a radially inner of the two shafts that extends radially outwards on its circumference and projects into the annulus; an inlet area through which the annulus can be filled siphon-fashion under centrifugal effect with a hydraulic fluid at least in an area of a free end of the fin as at least one of the shafts rotate; and at least one first opening branching off from the annulus for discharging a partial quantity of the hydraulic fluid from the annulus; wherein the annulus is formed by a first outer shell part and a second outer shell part which are connected to the radially outer shaft and the first outer shell part and the second outer shell part are arranged in a telescopic manner to form the annulus.
