The invention relates to a valve, in particular an expansion valve, for controlling a fluid flow, having a valve housing with an accommodation space and at least two fluid ducts connected to the accommodation space, having an opening which runs perpendicularly to the fluid ducts and opens into the accommodation space, wherein a sealing ring holder with a valve means is situated in the accommodation space, wherein the sealing ring holder with the valve means held therein can be inserted into the accommodation space through the opening, and wherein the valve means is positioned rotatably in the sealing ring holder by means of at least two sealing rings. The invention also relates to a sealing ring holder.

The invention relates to a thrust washer () for an electric machine () intended to be arranged on a shaft () between a bearing () and a rotor (), preferably a rotating electrical contact element () impacted by brushes (), and/or a disk pack () of the rotor (). The thrust washer () is provided with an area for sealing having two end faces (). On each end face (), at least one radial abutment section () for the bearing (), or the rotor (), is provided. The thrust washer () according to the invention is characterized in that it is made of at least one hard component () and one soft component (), wherein the part of the radial abutment section () abutting the rotor () and/or the bearing () is formed by the soft component ().

The invention relates to a multipole commutator motor ( ) having at least four stator poles ( ) and having armature coils ( ) that work together with these stator poles and that, for the supply of power, are each connected electrically with two commutator bars ( ) of a commutator ( ), and whose number is greater than the number of the stator poles ( ), it being provided that, in order to reduce the number of brushes ( ) contacting the commutator ( ), armature coils ( ), that form armature poles having identical magnetic orientation are connected in parallel through electrical bridge conductors ( ) at the armature. For the commutator motor ( ), it is proposed that the bridge conductors ( ) be routed at least partially via armature slots ( ).

In a device for connecting two parts for the sake of high-precision fixation of the two parts in a defined positioning to one another, two connection pairs are provided, each comprising one wedgelike tab, assigned to the first part and extending in the connection direction, and one wedge-shaped notch, assigned to the other part and extending in the connection direction, with a course of the wedge that is contrary to that to the tab, and into which notch the tab can be pressed, causing deformation. The two connection pairs are oriented such that the press-in directions of the tabs into the assigned notches are opposite one another in terms of the connection direction.

An electric motor having a housing, having an armature, having an armature shaft supported in two slide bearings, where one of the slide bearings axially displaceably receives the armature shaft and the other slide bearing limits an axial displaceability of the armature shaft by the disposition of a stop disk between a slide bearing bush of the slide bearing and the armature, by the disposition of an axial stop, in the form of a stop ring pressed over one end of the armature shaft. The armature shaft end protrudes out of the housing and is intended for carrying and driving a fan wheel that has a hub which is located adjacent the particular a slide bearing that receives only radial forces. The armature shaft end that carries the fan wheel is associated with the particular slide bearing that is designed as a bidirectionally acting axial bearing, and the hub of the fan wheel is brought so close to a face-end running face of the slide bearing bush that this hub on its face end forms an axial stop of the axial bearing. As a result, a special stop ring is unnecessary.
