Abstract

A functional component for influencing a tank ventilation of a fuel tank, functionally connected to an internal combustion engine, having a main body, wherein at least one flow channel for guiding fluid from an inlet side to an outlet side is formed in the main body, wherein at least one component for creating a clip connection of the functional component to an intake pipe is formed on the main body. The invention also relates to an arrangement of a functional component for influencing a tank ventilation of a fuel tank, functionally connected to an internal combustion engine, on an intake pipe.

First claim

What is claimed is:

1. A functional component for influencing tank ventilation of a fuel tank functionally connected to an internal combustion engine, the functional component comprising:
a main body;
at least one flow channel for guiding fluid from an inlet side to an outlet side, the at least one flow channel being formed in the main body; and
at least one component for creating a clip connection of the functional component to an intake pipe is formed on the main body,
wherein at least one clip is formed on the main body, the at least one clip having a clip head with a detent contour, and
wherein at least one cover structure is formed on the main body such that a loosening actuation of the at least one clip is prevented in an inserted locking position.

2. The functional component according to claim 1 , wherein the main body is formed at least as part of a Venturi nozzle or a valve or for receiving a Venturi nozzle and/or a valve.

3. The functional component according to claim 1 , wherein at least one clip mount for a corresponding clip disposed on the intake pipe is formed on the main body.

4. The functional component according to claim 3 , wherein the at least one clip mount is formed on the main body such that the clip connection between the functional component and the intake pipe is designed as a non-separable connection.

5. The functional component according to claim 1 , wherein the main body is formed in two parts.

6. An arrangement of a functional component on an intake pipe of an internal combustion engine, the functional component for influencing tank ventilation of a fuel tank functionally connected to the internal combustion engine, wherein at least one component that creates a clip connection is formed on the functional component and on the intake pipe of the internal combustion engine and wherein the functional component is clipped directly to the intake pipe,
wherein a clip is formed on the functional component, wherein the intake pipe has at least one clip mount which includes an insertion opening for receiving the clip and a demoldinq opening extending transverse to an insertion direction of the clip, and
wherein when the clip is fully inserted into the insertion opening, so as to be in a locking position, the demolding opening is completely closed by a cover structure disposed on the functional component, such that the clip, when in the locking position, is no longer accessible via the demolding opening.

7. The functional component according to claim 1 , wherein the at least one cover structure is provided on a side surface of the clip head, and wherein the at least one cover structure is plate-shaped and projects beyond the side surface of the clip head in both an insertion direction of the clip and a direction transverse to the insertion direction.

8. The arrangement according to claim 6 , wherein the clip of the functional component has a clip head with a detent contour, wherein the cover structure is provided on a side surface of the clip head, and wherein the cover structure is plate-shaped and projects beyond the side surface of the clip head in both the insertion direction of the clip and a direction transverse to the insertion direction.
