Patent abstract
The invention relates to a sealing device which is provided with an annular circumferential groove in a preceding sealing washer and having a sealing body disposed in the groove. The width and depth of the groove are larger than the cross-section of the sealing body so that the sealing body can be axially moved in the groove and may be forced against the wall of the groove and the tool shank by inner pressure provided, for example, by a coolant.
