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: 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.
