  • Patent number: 9745926
    Abstract: A fluid line coupling for a mechanical and fluidic coupling may include a fluid-carrying first component and a fluid-carrying second component. A pipe body may be at least one of integrated with and attached to the first component. A connection piece may be arranged coaxially to the pipe body in an inserted position, the connection piece being at least one of integrated with and attached to the second component. A securing clip may be disposed on an outer side of the pipe body and surround the pipe body in a circumferential direction at least 180°. The securing clip may be radially adjustable relative to the pipe body between a securing position in which the connection piece is secured to the pipe body in the inserted position, and a releasing position in which the connection piece is unsecured to the pipe body in the inserted position.

  • Patent number: 9453603
    Abstract: An arrangement for a fluidic and mechanical connection of two components may include a first component, a second component, and a coupling. The coupling may include a first coupling part arranged on the first component and a second coupling part. A damping part may moveably connect the second coupling part to the second component. An axial overlap region may be formed between the damping part and the second coupling part, which axially on the side facing the first component is bounded by a connecting region for realizing a mechanical connection between the second coupling part and the damping part. The second coupling part may coaxially plug into the first coupling part for fluidic and mechanical connection. At least one sealing element may be radially arranged between the first coupling part and the second coupling part.

  • Patent number: 9255658
    Abstract: A connection device may include an insertion section having an annular outer groove. A housing may be configured to receive the insertion section and a blocking element may be configured to lock the insertion section in the housing. The blocking element may have a band-shaped core and a plurality of teeth arranged adjacent in the peripheral direction along the core. Each of the teeth may include an outer tooth section and an inner tooth section. A core profile may have a core principal direction determined by a maximum diameter. The teeth may have a tooth profile which has a tooth principal direction determined by an inner flank of the teeth lying radially on an interior of the outer tooth section and the core principal direction may be inclined with respect to the tooth principal direction.

  • Patent number: 9121535
    Abstract: A coupling unit having at least one tubular section; a casing; at least one detent ring, which is arranged radially between the casing and the at least one tubular section when the at least one tubular section, is inserted in the casing, wherein the at least one detent ring, the casing, and the at least one tubular section are configured to adapt to one another such that the tubular section is inserted axially into the casing in a first relative rotational position of the tubular section and the casing, wherein the tubular section is secured by the detent ring against axial withdrawal, the casing and tubular section can be rotated relative to one another, and wherein for decoupling purposes, the tubular section can be withdrawn axially from the casing in a second relative rotational position of the casing and the tubular section that differs from the first rotational position.

  • Patent number: 8764067
    Abstract: A connection device may include an insertion section having an annular outer groove. A housing may be configured to receive the insertion section. A blocking element may be configured to lock the insertion section in the housing, wherein the blocking element may engage the annular outer groove and an annular inner groove formed in the housing. The blocking element may also be configured to be withdrawn through a housing opening substantially tangentially to the grooves and to be pre-fitted in the inner groove and in a pre-fitted state. The blocking element may engage the outer groove and be fixed on the housing securing it against a displacement in a peripheral direction. A securing device may be arranged on an exterior of the housing for securing of the blocking element against displacement at least in the withdrawal direction.
