Abstract
An intake system for an internal-combustion engine has an air line (air pipe) whose end is detachably fastened on a flange of a component. The flange of the component has at least one recess which, in the mounted condition of the connection, engages with fastening elements are provided on the air pipe, so that the air pipe is axially secured on the flange of the component.
Claims8
An intake system for an internal-combustion engine having an air line, of which an end is detachably fastened on a flange of a component of said engine, wherein:
- the flange of the component has at least one recess;
- and
- the air line includes fastening elements which, in a mounted state of the connection, engage with the at least one recess of the flange, whereby the air line, is axially secured on the flange of the component.
A coupling mechanism for detachably joining a fluid line to a component, said coupling mechanism comprising:
- a mounting flange provided on said component;
- a connection piece provided at an end of said fluid line, and having an interior cross sectional shape and size which corresponds to an exterior cross sectional shape and size of said mounting flange, whereby said connection piece can be nested with the mounting flange for coupling said fluid line with said component;
- at least one elongate member which is axially rotatably mounted in a sleeve on said connection piece;
- a notch extending along a side of said at least one elongate member, said notch having a longitudinal shape that corresponds to said exterior cross sectional shape of said mounting flange;
- and
- a notch provided on an exterior surface of said mounting flange, said notch having a transverse shape that corresponds to a transverse cross sectional shape of said elongate member;
- wherein said sleeve is arranged on said connection piece such that, when said elongate member is axially rotated into a position that is within a preset range, at least a portion of a side thereof projects within said interior contour of said connection piece, and when said elongate member is axially rotated into a particular rotational position which is outside said preset range, said notch faces said interior of said connection piece, whereby a side of said elongate member does not project within said interior contour of said connection piece.

An apparatus comprising:
- a component part;
- and
- a fluid line coupled to said component part by a coupling mechanism;
- wherein said coupling mechanism includes,
- a mounting flange provided on said component;
- a connection piece provided at an end of said fluid line, and having an interior cross sectional shape and size which corresponds to an exterior cross sectional shape and size of said mounting flange, whereby said connection piece can be nested with the mounting flange for coupling said fluid line with said component;
- at least one elongate member which is axially rotatably mounted in a sleeve on said connection piece;
- a notch extending along a side of said at least one elongate member, said notch having a longitudinal shape that corresponds to said exterior cross sectional shape of said mounting flange;
- and
- a notch provided on an exterior surface of said mounting flange, said notch having a transverse shape that corresponds to a transverse cross sectional shape of said elongate member;
- wherein said sleeve is arranged on said connection piece such that, when said elongate member is axially rotated into a position that is within a preset range, at least a portion of a side thereof projects within said interior contour of said connection piece, and when said elongate member is axially rotated into a particular rotational position which is outside said preset range, said notch faces said interior of said connection piece, whereby a side of said elongate member does not project within said interior contour of said connection piece.
