    摘要: A coupling part for a plug connector arrangement is provided. The coupling part having a coupling body comprising a receptacle into which a plug-in part can be plugged into in the direction of a longitudinal axis of the receptacle, in order to produce a fluid-tight connection. The coupling part has two spaced-apart locking elements which, in a locking position, penetrate laterally, opposite one another, into the receptacle in order to engage behind the plug-in part and which can be moved into a release position in order to release the plug-in part. A spring element is integrally formed with and connects the locking elements together. In order to develop the coupling part so that it is easier to handle, the coupling part is provided with an actuating element which is adapted to be moved relative to the coupling body. Movement of the actuating element causes the locking elements to be moved out of the locking position into the release position, in which they are spaced apart from one another to a greater extent than in the locking position.

    摘要: A method and a device for check-testing a braking system in which, before travel commences, a self-test of the braking system is performed. During the course of the self-test, the valve arrangements allocated to the wheel brakes and the pressure supply providing the brake pressure are driven in a predefined manner. A plurality of test phases are provided, after whose respective conclusions, a pressure level to be expected should be reached. Otherwise a secondary braking operation is initiated at least for the subsequent operating cycle of the vehicle.

    摘要: The invention relates to a hydraulic vehicle brake system with a hydraulic pump and a high pressure hydraulic accumulator for external power braking and a conventional master cylinder that is used as a braking power set point adjuster for external power braking and is used to actuate the brake system by muscle power in the event of a failure of the external power brake system. The system connects an intake side of the hydraulic pump to a low pressure hydraulic accumulator into which brake fluid travels from the wheel brake cylinders when the wheel brake pressure decreases. The system has the advantage that no connections of the hydraulic pump to a reservoir of the master cylinder are necessary, which in the event of a leak, would jeopardize the function of both the external power service brake system and the muscle power auxiliary brake system.

    摘要: A rotary nozzle for a high-pressure cleaning apparatus has a housing into which a feed line for a cleaning fluid issues, an outlet provided in the housing for expelling the cleaning fluid, a nozzle body through which the cleaning fluid flows, and a bearing that surrounds the outlet. The nozzle body is disposed in the housing, and is supported at its convex end in the bearing. The bearing is formed directly in an inner wall of the housing as a conically-shaped depression to avoid the need for a separate bearing insert, thereby simplifying the manufacturing process. Additionally, the conical shape of the bearing cooperates with the convex shape of the nozzle body to provide optimal sealing with a reduced contact surface for a long service life. The bearing is disposed concentrically relatively to the outlet. The nozzle body is set by the flow of cleaning fluid through the housing in a revolving movement in which a longitudinal axis of the nozzle body revolves on a generated cone.
