Sealing arrangement

A sealing arrangement (10, 10′) comprising:

• first and second separate armature members (11, 12), said armature members being fitted one within the other along conical contact surfaces (26a, 27a),
• a sealing ring (13, 13′) interposed between said first and second armature members, and
• a clamping means (30) for clamping the armature members (11, 12) against each other, said sealing ring (13, 13′) having a substantially T-shaped annular cross-section and including first and second sealing wings (15, 16) extending in opposite axial directions, each of the sealing wings (15, 16) including a radially outwards facing sealing face (15a, 16a), and a central, rigid stem (14) between the sealing wings (15, 16) and extending radially outwards thereof,
• each of the sealing faces (15a, 16a) being conically shaped to be supported against a radially surrounding, correspondingly conically shaped, intermediate, stop-forming, gliding and support face (21, 25) of a respective armature member,
• each of the intermediate conical support faces (21, 25) of the armature members (11, 12) extending at a first cone angle (a),
• the sealing face of each of the sealing wings (15, 16) extending at a second cone angle (b) greater than the cone angle (a) of the intermediate, stop-forming, conical support faces (21, 25) of the armature members (11, 12) prior to mounting, and after mounting extending at said first cone angle (a) to form a tight sealing abutment against the corresponding intermediate, stop-forming, conical support face (21, 25), wherein the entire rigid stem (14) and the first sealing wing (15) are seated in the first armature member (11), and the second sealing wing (16) is seated in the second armature member (12),
• wherein in the first armature member (11), a first side face (14b) of the stem (14) is seated in an axially facing, outermost guide surface (20), an end face (14a) of the stem (14) is seated in a radially facing cylindrical, outermost lying support face (22), and the first sealing wing (15) of the sealing ring (13, 13′) is seated in one of the intermediate, stop-forming, conical support faces (21), and, in the second armature member (12), a second side face (14c) of the stem (14) is seated in another axially facing, outermost guide surface (24), and the second wing (16) of the sealing ring (13, 13′) is seated in the other intermediate, stop-forming, conical support face (25),
• wherein the outermost lying support face (22) extends continuously in axial direction and solely in one of the armature members (11, 12), the outermost lying support face (22) being smooth to provide a continuous gliding support surface for the end face (14a) of the stem (14) directly against the outermost lying support face (22),
• wherein the first side face (14b) and the second side face (14c) of the stem (14) are dimensioned relative to the corresponding outermost guide surfaces (20, 24) so as to be spaced at a distance from the corresponding outermost guide surfaces (20, 24) after mounting.
