dadurch gekennzeichnet, dass die Ringsegmentmittel (74) ein einziges Ringsegment (86) aufweisen.
dadurch gekennzeichnet, dass die Ringsegmentmittel (74) ein einziges Ringsegment (86) aufweisen, welches anfangs in der Nut (62) positioniert ist, wobei der Raum (80) durch ein Abstandselement (82) geschlossen ist, welches durch eine Öffnung (23) in die Nut bildende Mittel (18) am Rotor (14) eingeführt wird, wobei der Raum (80) mit der Öffnung (23) ausgerichtet ist, wobei ferner das Abstandselement (82) und die Ringsegmentmittel (74) so weit bewegt werden, bis das Abstandselement (82) in dem T-Schlitz (20) eingefangen ist, und ferner dadurch gekennzeichnet, dass ein Loch (100) sich durch das Abstandselement (82) oder das Ringsegment (86) erstreckt und ausgerichtet ist mit einem Loch (38) in der Stirnfläche (34) des Rotors (14), und wobei ferner Mittel (26) in das Loch eingesetzt sind, um die weitere Bewegung zwischen den Abdichtmitteln (24) und dem Rotor (14) zu verhindern.
