Definitions
- the invention relates to an intake manifold for an internal combustion engine according to the preamble of claim 1.
- Such a suction pipe is known from DE 25 26 550 A.
- suction pipes made of correspondingly lighter materials (especially plastic or aluminum).
- Made of die-cast aluminum or plastic injection Series-made suction pipes have a wall thickness of about 2 millimeters.
- DE 25 26 550 A is to avoid damage to the intake manifold and a secondary outlet (opening) is provided to discharge the disproportionate pressure, when a predetermined pressure is exceeded within the suction tube is opened.
- the secondary outlet is initially a cup-shaped one Cover closed, on a nozzle on the outside of the intake manifold wall is attachable.
- this pot-shaped lid has the decisive disadvantage that it releases the secondary outlet when intake manifold explosions occur and thus creates a pressure balance in the atmosphere; after the suction pipe explosion has subsided and release of the secondary outlet is the continued operation of the internal combustion engine however, in no case possible, since after opening the secondary outlet the circuit of the fuel pump or the ignition current of the internal combustion engine is interrupted.
- the cover To put the engine back into operation, the cover must first be put back on, for example, the circuit for the fuel pump to close again and start the internal combustion engine. This means that the vehicle stops in the event of an intake manifold explosion, which means that safety-critical situations occur especially while driving can. In addition, it is not guaranteed that the driver of the vehicle in the If the internal combustion engine fails, the opening with the cover is closed again lock so that the vehicle may have to be towed to the workshop.
- the object of the invention is to create a generic one To design the intake manifold so that the disadvantages described are avoided.
- the drawing shows a section through a section 1 of a downstream one shown throttle valve connector lying plastic / metal intake manifold, that too 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 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 with a stem 5 into a central opening 6 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, is pushed onto a cover flap 11 and clipped with 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 by Explosive occurrences that occasionally occur after starting the internal combustion engine Ignition of stored / condensed in the intake manifold 1 and with the in Intake pipe 1 contained air mixed fuel / fuel vapor residues is caused.
- this pressure increase is caused by opening of the valve 3 limited.
- the air / fuel gas can escape into the free atmosphere.
- the burning gas cools down in the opening 2 divided by ribs 13 and also in the outlet opening 13 covered by the cap 11 between Screw bushing 8 and collar ring 10.
- valve 3 closes again Internal combustion engine remains ready for operation.
- the cap 11 prevents entry of dirt and water into the opening 2.
