A mechanism for changing the operating condition of a shifting element having two shifting element halves, which can either be functionally connected to connect two components or disengaged to break the connection between the components. The mechanism includes a drive machine and a drive converter unit in the area of which rotary drive motion of the drive machine can be converted into a translational actuation movement of the shifting element. A spring device is associated with the drive converter unit, whose spring force assists with actuating the shifting element in the engaging direction. The spring device includes an approximately circular flat spring element which, in at least one area of the drive converter unit, is in contact with at least one cam, whose stress condition varies as a function of an operating condition of the drive converter unit and is designed to be rotationally fixed.

A hybrid yarn and a fabric including the hybrid yarn are provided. The hybrid yarn is formed of a plurality of fibers of a plurality of different fiber compositions. The fibers of different configurations are homogenized and intimate with one another throughout the yarn. The yarn may be formed using fibers made of the same material or a plurality of different materials. The different fiber compositions may include fibers of three or more different cross sections, fibers made of different materials or a combination of the two. Fibers having tips or ends are made so that the tips are rounded rather than squared to improve the manufacture and quality of the yarn. The materials may be synthetic and/or natural materials. Fabrics made with the hybrid yarn will have selectable functional features and also be of lighter weight than previously possible. Hybrid spinnerets may be used to produce hybrid yarns with three or more different fiber cross sections wherein spinneret portals that have tips are made with the tips rounded.

A method for the operation of a vehicle drive-train of a working machine having a drive motor, a transmission whose transmission ratio can be varied continuously, and a drive output.

The constant pressure control valve has the advantages that by increasing the diameter of the valve body, the diameter of the main sliding valve element in the valve body is increased, so that the response speed of the high-pressure plunger pump is increased; the inner valve element is placed in the main sliding valve element, so that the axial thrust of the main sliding valve element under the high-pressure working condition can be reduced, and the control force of the pressure adjusting spring assembly is reduced; when the diameter of the main sliding valve element is increased, the thrust for pushing the main sliding valve element can be kept unchanged by reducing the sectional area of the inner valve element, so that the adjusting force of a spring is small, and the appearance of the pressure adjusting spring assembly is compact; and when the set pressure needs to be remotely controlled and adjusted, remote pressure control over pressure oil introduced into the pressure adjusting spring assembly can be achieved only by disassembling the inner valve element in the valve element assembly.
