ABSTRACT OF THE DISCLOSURE The invention relates to a device for sealing a casing housing a machine element the rotatable shaft of which passes through the casing within which a pressure differing from that of the outside the casing is maintained. To provide a perfect sealing at the shaft passage, a liquid seal is formed by novel specific means. In a preferred embodiment where the device is combined with an apparatus the shaft of which passing through at least one wall of the casing is axially displaceable, the specific sealing means are displaceable together with the shaft while completely maintaining the sealing effect. - 1 -
