Abstract

The present invention relates to a device for the leak-tight or leakage-controlled transfer of a fluid between a first part and a second part, which are arranged to coaxially interact with each other, and, in an operating mode, to be turned and/or rotated in relation to each other, the said first part including a pressure sealing element, which comprises a first sealing surface for interaction with a second sealing surface present on the said second part. The said pressure sealing element is arranged so as to be axially movable relative to a seat in the said first part, and the pressure sealing element is arranged in the seat such that it is pressure balanced, at least in the radial direction, under the action of pressure. The present invention also relates to a rock drilling tool and a rock drilling machine.
