Definitions
- the invention relates to a thin-walled intake manifold for an internal combustion engine according to the preamble of claim 1.
- suction pipes are increasingly used because they are considerably lighter are as thin-walled suction pipes and in terms of their surface and shape can be designed more freely. They are made of metal or plastic, both of which lack strength
- the invention is therefore based on the object of a generic To design the intake manifold so that the lack of strength compensates and the bursting of the thin-walled suction pipe is excluded.
- the drawing shows a section through a section 1 of a downstream Throttle valve seat, not shown, lying plastic / metal suction pipe, that leads to one of the cylinders of the internal combustion engine.
- this intake manifold is provided downstream of the throttle valve connector to arrange an opening 2 leading into the atmosphere, which through a valve 3 responsive to the pressure in the intake manifold 1 is controlled.
- This valve 3 is a so-called elastomer umbrella valve 4, which projects into a central opening 6 with a stem 5 and is held by a stud 7 of a screw bushing 8.
- the screw bushing 8 has a collar ring 10 spaced apart by ribs 9 on which a cover cap 11 is pushed and clipped to it, the ribs 9 of the screw bushing 8 form a tool attachment 12, so that the screw bushing 8 can be screwed into the opening 2.
- the invention is based on the knowledge that the bursting of the suction pipes 1 due to an explosion-like occurrence that occurs occasionally after the engine is started Ignition of stored / condensed and in the intake manifold 1 mixed with the air contained in the intake manifold 1 fuel / fuel vapor residues is caused.
- this pressure increase is caused by opening of the valve 3 limited.
- the air / fuel gas can be released into the free atmosphere emerge.
- the burning one cools in the opening 2 divided by ribs 13 Gas from and also in the outlet opening covered by the cap 11 13 between screw bushing 8 and collar ring 10. Then closes valve 3 again, the internal combustion engine remains ready for operation.
- the cover cap 11 prevents dirt and water from entering the opening 2.

Description
Claims (4)
- Dünnwandiges Saugrohr für eine Brennkraftmaschine mit Anschlußkanälen, die zu den Zylindern der Brennkraftmaschine führen, und wenigstens einem Drosselklappenstutzen, mit dem die von der Brennkraftmaschine angesaugte Brennluft gesteuert wird, dadurch gekennzeichnet, daß in dem Saugrohr (1) stromab des Drosselklappenstutzens eine in die Atmosphäre führende Öffnung (2) angeordnet ist, die durch ein auf den Druck im Saugrohr (1) ansprechendes Ventil (3) gesteuert wird.
- Saugrohr nach Anspruch 1, dadurch gekennzeichnet, daß das Ventil (3) von einem Elastomer-Regenschirmventil (4) gebildet ist, das mit einem Stiel (5) in eine zentrale Öffnung (6) hineinragt und durch einen Stiftansatz (7) einer Schraubbuchse (8) gehalten ist.
- Saugrohr nach Anspruch 2, dadurch gekennzeichnet, daß die Schraubbuchse (8) einen durch Rippen (9) beabstandeten Kragenring (10) aufweist, auf den eine Abdeckkappe (11) aufgeschoben und mit diesem verklippst ist.
- Saugrohr nach Anspruch 3, dadurch gekennzeichnet, daß die Rippen (9) der Schraubbuchse (8) einen Werkzeugansatz (12) bilden, so daß die Schraubbuchse (9) in die Öffnung (2) eingeschraubt werden kann.
