Abstract: A method for mounting a hydrodynamic sliding bearing of a shaft, in particular a magnetic coupling pump, wherein the hydrodynamic sliding bearing includes a bearing bushing disposed between a bearing sleeve and a bearing housing includes the steps of A coating a clamping ring on at least one of its surfaces with a friction-increasing coating, B heating the clamping ring and applying to the bearing bushing so that a pre-assembly unit is formed, and C heating the bearing housing, wherein the pre-assembly unit is inserted in the bearing housing. A double pressure bond is thus advantageously provided where a radial prevention of rotation and an axial prevention of displacement is achieved without any axial pinning as prevention from rotation and axial tensioning (e.g. L-profile ring) of the bearing bushing being required.

The split case has a flange which can be fixed with a counter-flange on a coupling component. The split case is made of a ceramic, whereas the coupling component and the counter-flange are formed from a metal material. Provided on the flange is a spherical elevation which engages in a corresponding, spherical indentation. A compensating element is arranged between the flange and the counter-flange and can have a spherical indentation corresponding to the spherical elevation on one of its front sides.

Abstract: An arrangement is provided for feeding a liquid additive from a receptacle into a fuel line or into an exhaust line of an internal-combustion engine of a motor vehicle by way of a blockable feed line leading into at least one of the above-mentioned line and by way of a pump which at least temporarily generates a feed pressure in the feed line. The receptacle can be filled with additive from a larger storage tank also accommodated in the motor vehicle by way of a connection line that can be blocked. The feed line branches off the connection line between the receptacle and the storage tank. The pump is installed in the receptacle or between the receptacle and the branching-off of the feed line into the connection line. The connection line can be shut-off in the storage tank or between the storage tank and the branching-off of the feed line.
