Abstract: The invention relates to a valve for controlling volumetric flows in a heating and/or cooling system of a motor vehicle, comprising a valve housing (10), from which at least one inlet channel (18) and at least one outlet channel (20, 22) branch, in addition to at least one disc-type valve body (28) for controlling the flow, said body being located in the valve housing so that it can rotate about the axis (31) of a driven shaft (30). According to the invention, the valve body (28) is operatively connected to an electromotive drive (24) by means of a gear system (64). The invention also relates to a heating and/or cooling system (110) of a motor vehicle, comprising a valve (131) of this type.

Abstract: The invention relates to a wiper drive comprising a housing, a reversing motor and a gear mechanism connected downstream of the reversing motor, wherein a swaying element for driving at least one wiper arm or a wiper arm rod is provided on the gear mechanism output shaft, and wherein the operating range of the swaying element lies within a pivoting range which is delimited by two mechanical stops, wherein at least one stop is designed such that it can be removed and/or moved in such a way that the swaying element, when the wiper drive is mounted on a support frame, can be moved from a first mounting position, which lies outside the pivoting range, into the pivoting range without being obstructed by the stop. The invention furthermore relates to methods for mounting a wiper drive on a support frame.

Abstract: A primary element for an electrical machine has a magnetically conductive body including a lamination stack with a plurality of axially extending teeth disposed in a star pattern, and a winding of annular coils wound separately as coil-body-less air coils and mounted radially onto the teeth. To attain an axially and radially play-free seat of the annular coils on the teeth, on each face end of the magnetically conductive body, one compensation element, which is elastically deformable in the axial direction of the tooth, is placed on each of the face ends, located in a transverse plane to the body axis, of the teeth, onto which compensation element the annular coil slipped onto the tooth is pressed axially. All the compensation elements on one face end are joined together via a closed ring element to make a one-piece compensation mask of insulating plastic.

Abstract: For the production of cigarette groups (11) having a formation comprising a plurality of vertical rows of cigarettes (10) arranged one beside the other, after pushing a corresponding number of cigarettes (10) out of shafts (13) of a cigarette magazine (12), a transverse displacement of the cigarettes (10) is required in order to arrange same in a tightly packed or saddle configuration. At least marginal push rods (18) for pushing the cigarettes (10) out of the shafts (13) of the cigarette magazine (12) can be displaced transversely together with the cigarettes.

Abstract: For the production of (cigarette) packs of different configurations, for example standard pack (13), round-edged pack (14) or octagonal pack (15), subassemblies and elements of the packaging machine are exchanged and/or uncoupled from the drive. For this purpose, a pack-specific operating element is provided with a drive which has a coupling and/or uncouplable gear-mechanism parts. These, in turn, are assigned operable handling elements which allow adjustment for coupling or uncoupling or removing sub-elements.
