Abstract

The air induction channel system has a storage chamber integrated in a component. The adapter forming the negative pressure store (17) has a storage chamber (18) closed off by a cover insert (19) held by the walls (20) of one of the part components (4, 5). This leads via an aperture (14) to the storage chamber. A non-return valve (12) controls this aperture.

Dieses weist einen zentral angeordneten Sammeleinlaßkanal 6 auf, in den ein Lufteinlaß­ kanal 7 einmündet, der von einer Drosseleinrichtung 8 kontrolliert wird. Von dem Sammeleinlaßkanal 6 zweigen spiralförmig ausgebilde­ te, zu den Zylindern der Brennkraftmaschine führende Einzelansaug­ kanäle 9 ab. Fig. 1 shows a cross section of an air intake duct system 1 of the prior art of an internal combustion engine, from which a cylinder head 2 of the internal combustion engine and a parting plane 3 of sealing surfaces of two sections 4 , 5 can be seen, which screwed together form the air intake duct system 1 . This has a centrally arranged collecting inlet duct 6 , into which an air inlet duct 7 opens, which is controlled by a throttle device 8 . From the collective inlet duct 6 branches spirally formed te, leading to the cylinders of the internal combustion engine individual intake ducts 9 .

Die in bezug auf den Sammeleinlaßkanal 6 innenliegenden Wandungen der Einzelansaugkanäle 9 und die Wandung des Sammeleinlaßkanals 6 sind von einem spiralförmigen Paßstück 10 und einem weiteren als Formblasteil 11 ausgeführten Paßstück gebildet, die von den Dichtflä­ chen ausgehend in die entsprechenden Ausnehmungen der Teilstücke 4, 5 eingesetzt sind.The inboard with respect to the common intake passage 6 walls of Einzelansaugkanäle 9 and the wall of the collecting intake passage 6 are formed by a spiral-shaped fitting 10 and another fitting constructed as Formblasteil 11 of the Dichtflä of the sections 4, 5 chen starting inserted into the corresponding recesses are.

Das Formblasteil 11 dient als Unterdruckspeicher, der über ein Rück­ schlagventil 12 (Fig. 2) mit dem Sammeleinlaßkanal 6 und mit Unter­ druckanschlüssen 13 über Unterdruckleitungen mit den entsprechen­ den Pneumatikelementen von Motor- bzw. Fahrzeugausrüstungen ver­ bunden ist.The molded part 11 serves as a vacuum accumulator, which is connected via a check valve 12 ( FIG. 2) to the collective inlet duct 6 and to vacuum connections 13 via vacuum lines with the corresponding pneumatic elements of engine or vehicle equipment.
