  • Patent number: 6530604
    Abstract: A coupling arrangement connects two elements with each other. The coupling arrangement includes a plug element and a bushing element which are configured in such a manner that they can be plugged together and locked in position by means of an expandable retaining ring. An axially movable release arrangement cooperates with the retaining ring in order to release the locking mechanism. The coupling arrangement is characterized in that the release arrangement (41) comprises a release sleeve (43), which can be closed with a cover (51) on its side facing away from the bushing element (5), and that a blocking device (55) is used to prevent an inadvertent release of the coupling.

  • Patent number: 6158472
    Abstract: Apparatus damps pulsations of a fluid conveyed through a conveying device. The fluid is led by way of a first tubular element into a cavity formed by a flexible element and emerges from the cavity by way of a second tubular element. The tubular elements are arranged within the cavity in the flexible element. The length of each of the individual tubular elements is less than the length of the cavity; however, the sum of the lengths of the tubular elements is greater than the length of the cavity.

  • Patent number: 6102448
    Abstract: An arrangement for connecting two pipe ends comprising a respective closure part around each of the pipe ends. The closure parts are connected together in a bayonet-type connection. One closure part includes an annular surface with a first part parallel to a sealing device placed between the pipe ends and with a second part inclined with respect to the sealing device. The latter part draws the closure parts and the pipe ends together as the closure parts are rotated relatively toward each other and as the one closure part is guided along the inclined portion of the annular surface. A respective sealing surface is provided on each of the pipe end parts. The sealing surfaces are brought axially toward each other by movement together of the closure parts.

  • Patent number: 6047790
    Abstract: A device for damping the sound emission from oscillatory components of a fluid container of a hydraulic system, primarily in a motor vehicle. At least one vibration damping mass is coupled to the wall of a component subject to sound damping. The mass is adapted to the vibration to be damped by selection of material, shape, and/or position on the wall. For example, the mass is a rib fastened to the wall or a strip adhered to the wall. In an alternate embodiment, the container has an inner and an outer wall with a gap between them. The gap is either evacuated, filled with a sound absorbing material or ribs on the wall extend in the gap or inside the inner wall.
