  • Publication number: 20150176740
    Abstract: The present invention relates to a connecting device (5, 5?) for connecting at least two pipe parts, wherein the connecting device is connected at least in portions to a first pipe part, and a detachable connection to at least one connecting element (3, 4) operatively connected to a second pipe part (1) can be produced by means of said connecting device. The connecting device comprises at least one locking ring (7, 7?) with at least two elastically movable catch tabs (11 11?) protruding in a radially inward direction of the locking ring, and at least one actuator ring (9, 9?) for moving the catch tabs out of at least one locking position, in which at least one of the catch tabs is engaged in the connecting element, into at least one unlocking position in which the engagement is detached, and vice versa. The respective catch tab is resiliently mounted at a first end on the locking ring via at least one catch arm (21, 21?), and a second end of the catch tab opposite from the first end is freely movable.

  • Patent number: 7086833
    Abstract: A housing part, which can be firmly joined to another housing part for the formation of a housing of a radial flow compressor, in particular a turbocharger. At least one open or closed channel portion is provided in each housing part so that when the housing parts are joined a channel system is formed which runs between the two housing parts. A free-flowing and hardening compaction material, such as an adhesive or a thermoplastic polymer, is inserted into the channel system for the formation of a firm bond between the two housing parts.
