Definitions
- the invention relates to a suction device for a Internal combustion engine according to the preamble of the main claim.
- a controllable shut-off device is available.
- the shut-off device is located in one between two intake ducts located cross channel and is controlled by commands control electronics opened or closed.
- the Control commands are dependent on the speed of the internal combustion engine and the temperature of the outside air with a temperature sensor is determined.
- Another suction device according to the preamble of claim 1 is from DE-A-1 928 925 known.
- the invention has for its object a suction device for an internal combustion engine according to the generic term of the main claim to train that with simple means and adaptation without additional control devices the passage opening of the suction device to the Operating states of the internal combustion engine is possible.
- the suction device according to the invention solves the posed Task with those specified in the indicator of the main claim Characteristics.
- the suction device according to the invention is particularly advantageous in that in particular the noise emission of the Internal combustion engine through a simple speed-adapted Size of the passage opening for the suction Air volume is greatly reduced. Is optimal for each speed of the internal combustion engine a certain size the passage opening, being at low speeds small diameter for the lowest possible noise emission leads.
- variable passage openings are simple realized by means of a passive flap mechanism that in the space fixed by web-like spacers is formed between the tubes. To open the Flap mechanism is sufficient here to increase the suction pressure, for example with an increase in the speed of the Internal combustion engine.
- the flap mechanism is particularly advantageous according to one of claims 3 to 5 as an elastic sealing lip executed, which is held on one side and in movable part so movable away from the other tube surface is that they completely open the additional passage or partially releases.
- This elastic sealing lip is preferably made of a temperature-stable elastic material, e.g. B. elastomer, TPE or the like, made, so that the opening behavior is largely independent of temperature is.
- a temperature-stable elastic material e.g. B. elastomer, TPE or the like
- the elastic Sealing lip additionally slotted at the free end, so that the free parts are even more mobile.
- a possibly necessary Contact pressure of the free part on the other pipe can easily be made by a ring spring become.
- the at least one inner tube is slightly longer than the outer tube and thus protrudes from the level of the entrance opening. To this This can create turbulence and a vacuum in the additional Passage can be largely avoided, which affect the suction behavior negatively.
- FIG. 1 is a suction device 1 for one here Internal combustion engine, not shown, shown by the an air stream is drawn in according to arrow 2.
- the suction device 1 has an inner tube 3, an outer tube 4 and web-like Spacer 5 between the tubes 3 and 4.
- the Inner tube 3 is above the level of the inlet opening 6 extended by a predetermined amount.
- Sealing lip 7 held, which is freely movable within limits Part 8 has.
- the sealing lip 7 is with the free part 8 led obliquely backwards in the suction direction, so that at a certain increase in suction pressure the free part 8 of the sealing lip 7 moves away from the inner tube 3 and an additional passage for the Airflow releases.
- Figure 2 is a section through the suction device according to Figure 1 shown, in particular the location of the web-like Spacer 5 between the tubes 3 and 4 illustrates.
- Figure 3 shows a first embodiment of the sealing lip 7 with the movable free part 8 in detail, wherein in the right half of Figure 3 is a plan view of the sealing lip 7 is shown.
- slots 9 are attached, one Support locomotion of the free legs of the sealing lip.
- the number and size of the slots 9 will depend of the pressure conditions in the suction device or the operating conditions of the internal combustion engine or Elasticity of the sealing lip 7 selected.
- Figure 5 are instead the slots 9 folds 10 attached, which are comparable Way as the slots 9 based on Figure 4 Support opening of sealing lip 7.
- the embodiment of Figure 6 also assigns the slots 9 still an annular spring 11, which a predetermined Contact pressure of the sealing lip on the inner tube 3 causes. For certain applications, it is necessary a passively controlled opening behavior of the To ensure sealing lip 7, so only from one the spring action of the ring spring 11 predetermined suction pressure the additional passage opening is activated.
- Figure 7 and Figure 8 each show another embodiment the sealing lip 7 with a belly-like extension of the free part 8, some of which is a certain Can have rigidity in a region 12.
- the variation the passage opening also takes place here through the arrangement of slots 9 (FIG. 7) or by folding 10 (Figure 8).
- Figure 9 shows an embodiment of a suction device 1 with a sealing lip 13 which is attached to the inner tube 3 is and rests with its movable part on the outer tube 4. Further arrangement options for the sealing lips 13 result from FIG. 10 (fastening in the area of the outlet opening 14 on the outer tube 4) and from FIG. 11 (Attachment in the area of the outlet opening 14 on the inner tube 3).
- the constructive embodiments of the sealing lips 13 are adapted here to the respective applications and can be the one described in FIGS. 3 to 8 Use characteristics with regard to mobility.
- FIG 12 Another design possibility of the inner tube 3 shows Figure 12, in which the inner tube 3 over the level of the outlet opening 14 is led around the fluidic to ensure the most favorable form when the air flow exits.
- a dashed line 15 is also a shortened shape of the inner tube 3 indicated in the the inner tube ends in front of the outlet opening 14.
