Abstract: A winding pack for a stator assembly of an electric motor, including a coil assembly having twelve coils arranged in three groups, each having four coils of a winding, which are interleaved circumferentially. Each group has two pairs of adjacent coils, between which two pairs of the other groups are positioned. All groups have an identical sequence of their winding direction. Each pair contains both winding directions, the order of which differs between the two pairs. The technical winding start coming from one of the terminal regions in the pair that is first when viewed in the circumferential direction and the technical winding end leading to one of the terminal regions in the second pair of the relevant group are located, in relation to the winding pack, at the end face and on the side of the relevant second coil of the pair facing the first coil of this pair.

Abstract: An integrally molded internal rotor core of a brushless electric motor includes a central bore, and the rotor core is manufactured by a cold extrusion process.

Abstract: A transmission housing assembly includes a transmission housing and a freewheel including an inner ring and an outer ring. The inner ring is non-positively connectable to a motor shaft. The transmission housing includes a steel bearing bush overmolded with aluminum, which defines an opening of the transmission housing into which the freewheel is pressed.

Abstract: A transmission housing assembly includes a transmission housing and a freewheel including an inner ring and an outer ring. The inner ring is non-positively connectable to a motor shaft, and a steel bearing bush is inserted into an opening of the transmission housing, into which the freewheel is pressed in order to press-fit the outer ring with the steel bearing bush and the transmission housing.

Abstract: A method of manufacturing a motor shaft of an electric motor which is part of an actuator providing a rotary actuating movement of an actuator through a transmission, includes providing a cylindrical shaft blank including a second end and a second end portion extending from the second end. An outside diameter of the second end portion is greater than outside diameters of all remaining portions of the shaft. The method further includes forming a toothing into the second end portion, and grinding the toothing to size in a region spaced from the second end to define a bearing seat, an outside diameter of the bearing seat being less than an outside diameter of an engagement region of the toothing between the bearing seat and the second end.

Abstract: In a washing nozzle for use on vehicles for applying a liquid cleaning or washing medium, means are provided for acting within the nozzle on a main jet generated in the nozzle with a collision jet in order thus to modify the nozzle jet which emerges.

Abstract: An integrally formed, one-piece construction nozzle body having a primary flow channel and associated secondary flow channel and outlet configuration which cooperate to produce a jet of fluid having a predetermined geometric configuration. A system and method are also shown for creating the one-piece construction nozzle body.

Abstract: A method for forming an embodiment of a fluid nozzle assembly includes removing two cores in opposed directions from a die set having a mold cavity configured to be a negative replica of the fluid nozzle assembly. The cavity includes the two cores, with one core configured to be a negative replica of: a fluid connector receiving bore; an inlet region of a nozzle; and a pass-through conduit, each in fluid communication with the fluid connector receiving bore. The other core is configured to be a negative replica of an outlet region of a nozzle in fluid communication with the inlet region. Removing the cores forms the nozzle assembly after molten polymeric material injected into the mold cavity has solidified. Removing leaves substantially no flash: at an area where the inlet region and the outlet region meet; and at an end region of the pass-through conduit distal to the receiving bore.

Abstract: In a washing nozzle for use on vehicles for applying a liquid cleaning or washing medium, means are provided for acting within the nozzle on a main jet generated in the nozzle with a collision jet in order thus to modify the nozzle jet which emerges.

Abstract: The invention relates to a control valve, a nozzle arrangement and a washing device for vehicle windscreens, the valve having at least two outlets that are coupled or couplable with the nozzle opening or openings, the valve having an inlet that is coupled or couplable with a feed pump for the cleaning fluid, and with provision for a valve body influencing the path of the cleaning fluid from the inlet to the outlets. The invention is characterised in that the valve body is more controllable by the pressure of the cleaning fluid in at least two valve positions.

Abstract: The invention relates to a nozzle and a washing system in particular for vehicle windscreens, comprising a nozzle body with a receiving device provided in the nozzle body, into which receiving device a nozzle insert is or can be inserted, wherein the nozzle insert influences the jet form of a liquid jet leaving the nozzle. The invention is characterized in that the receiving device has at least two inlets for the cleaning liquid and in that the nozzle insert is designed such that it influences the cleaning liquid coming from one inlet in a different manner from the cleaning liquid coming from another inlet.
