Definitions
- the invention relates to a throttle valve device according to the preamble of claim 1.
- throttle valve devices in particular electrically actuated throttle valve devices for internal combustion engines, have a throttle valve housing in which one
- Throttle valve for changing a flow cross-section for a gas is pivotally arranged.
- the throttle valve is optionally designed to be electrically drivable.
- the throttle valve housings of known throttle valve devices are usually made of metal or a thermosetting plastic.
- the throttle valve housing is closed by a cover which, on the one hand, serves as a cover for a drive housing and, on the other hand, forms an abutment for a throttle valve shaft in the area of a passage cross section of the throttle valve device.
- Both the throttle valve housing and the throttle valve cover have fastening devices by means of which the throttle valve device can be fastened to an air filter device arranged upstream in the flow direction and to an intake pipe device arranged downstream in the flow direction.
- the object of the invention is to provide a throttle valve device which substantially reduces the assembly effort of an intake tract of an internal combustion engine and still the requirements placed on a throttle valve device with regard to durability, moisture resistance and dimensional accuracy. Furthermore, the throttle valve device should be easy to manufacture with few components and inexpensively.
- a throttle valve device has at least two housing parts and a throttle valve, one of the housing parts having a throttle tube section which interacts with the throttle valve, the other housing part being formed in one piece with at least one upstream or downstream channel section.
- the cover of the throttle valve device according to the invention is formed according to the invention from a much cheaper thermoplastic.
- at least one intake manifold section is integrally connected to the cover of the throttle valve device. This enables at least a relocation of the mounting level between the throttle valve device and a downstream intake manifold, ideally even the avoidance of such a mounting level, namely when the entire intake manifold is connected in one piece to the throttle valve cover.
- a mounting level can be completely omitted.
- FIG. 1 is a perspective view of a throttle valve device according to the invention.
- FIG. 2 shows a further illustration of a throttle valve device according to the invention from a different perspective as shown in FIG. 1, so that the interior of the intake manifold section is visible;
- FIGS. 1 and 2 shows a side view of the throttle valve device according to the invention according to FIGS. 1 and 2.
- a throttle valve device 1 according to the invention (FIGS. 1 to 3) has a throttle valve housing 2 and a throttle valve housing cover 3.
- the throttle valve housing 2 has a throttle tube section 4 and a drive housing section 5.
- the throttle valve housing cover 3 has a drive housing cover section 6, which is connected to a pipe flange 7.
- the drive housing section 5 and the drive housing cover section 6 form a parting line 8, which separates the drive housing, consisting of the drive housing section 5 and the drive housing cover section 6, approximately symmetrically.
- the throttle tube section 4 of the throttle valve housing 2 and the tube flange 7 of the throttle valve housing cover 3 form a second parting line 9.
- the second parting line 9 is arranged at an angle to the first parting line 8, so that the sealing surfaces of the throttle valve housing 2 and the throttle valve housing cover 3 forming the parting lines 8, 9 between the arrival drive housing 5, 6 and a throttle tube 10, consisting of the throttle tube section 4 and the tube flange 7 meet to form a kink.
- the position of the parting line is selected such that a throttle valve shaft 11 of a throttle valve 12 is rotatably mounted in each case via a bearing recess in the throttle valve housing cover 3 and in the throttle valve housing 2.
- the latter is only supported in a suitable recess in the interior of the throttle tube section 4 such that the tube flange 7 is not involved in the mounting of the throttle valve shaft 11 there.
- the throttle valve housing 2 is preferably made from metal or from thermosetting plastic, since these materials are able to maintain the required tolerances even over a long period, in particular under the influence of moisture or strongly fluctuating temperatures. According to the invention, it has now been recognized that by reducing the function of the throttle valve housing cover 3 to only one cover function, it is possible to produce it from less expensive material, in particular from a plastic that can be processed in an injection molding process.
- thermoplastic materials such as PA 6, PA 6.6, PA 4.6 or thermoplastic mixed plastics have proven to be suitable for this purpose.
- the throttle valve housing cover 3 can be produced based on the choice of material by means of common injection molding processes, at least a partial region of an intake manifold is arranged in the region of the tube flange 7, that is to say that at least one intake manifold section 15 which is arranged in a flow direction 16, e.g. B. downstream with respect to the throttle tube section 4, is integrally formed with the throttle valve housing cover 3. In a preferred manner, this is usually arranged between the throttle valve device 1 and the internal combustion engine or its intake spider. netes intake manifold as a whole with the throttle valve cover 3 integrally connected.
- an intake manifold section 15 is integrally formed on the throttle valve housing cover 3, depending on the length of the intake manifold section 15 and depending on the shape of the intake manifold section 15 with regard to its tubular shape, this allows a free choice of the attachment plane to the component following the intake manifold section 15.
- the intake manifold section 15 or the intake manifold is essentially cylindrical and is characterized in that it has no interaction surfaces with the throttle valve 12 or its boundary edges.
