Definitions
- the invention relates to an intake system for internal combustion engines according to the upper Concept of independent claim 1.
- Such intake systems are generally known and usually have one Raw air area and a clean air area. These two areas are separated by one Air filter element separated from each other.
- additional elements are provided that have certain functions, such as. B. resonance rooms or other soundproofing agents.
- the housings are usually made made of a thermoplastic and are injection molded manufactured.
- EP 0.896.148 shows e.g. such an intake system. Especially with very complicated interior structures are complex Injection molds required.
- DE 42 03 696 describes a device for injection molding a Plastic molding known.
- This device is suitable for molded parts with undercuts manufacture.
- Such molded parts are containers of all Art.
- the device has an inner core belonging to the locking part, which has a includes the slider delimiting the cavity. These sliders are with oblique course in the direction away from the cavity.
- the invention has for its object to avoid the disadvantages mentioned and to provide an intake system for an internal combustion engine which is simple and can be manufactured inexpensively.
- This task is based on the preamble of independent claim 1 solved by its characteristic features.
- the main advantage of the invention is the fact that in the housing Resonance room is created, which has an acoustic neck with the other Housing volume is connected.
- the creation of a resonance room previously required additional inserts such as a second floor that is welded or glued into the housing had to.
- the invention provides for the acoustic in a two-part housing Arrange the neck so that on the one hand a part of it is in the first part of the housing and another part of the acoustic neck in the second section of the housing. It can be used without a additional insert a resonance chamber in a housing of an intake system create.
- Another embodiment of the invention provides for the connection between the resonance space and to arrange the housing volume in the center of the housing so that the best possible effect is achieved. If the two housing parts together be welded is a coupling or an airtight connection of the two-part acoustic neck required. This can be done, for example, by that the heat generated during the merging or Melting a seal is used.
- the intake system according to FIG. 1 consists of a housing 10 with an opening 11 for supplying the raw air.
- the housing is closed with a cover 12.
- a filter element 13 in the housing.
- the filter element 13 consists in particular from a zigzag-shaped folded filter paper, which is a circumferential Has seal 14. This filter element and the seal separate the raw air space 15 from the clean air space 16.
- the cleaned air flows through the opening 17 to the Internal combustion engine not shown here.
- a resonance partial volume 18 is arranged on the housing. This resonance sub-volume stands over a so-called acoustic neck 19 with an upper resonance Partial volume 18a in connection.
- the resonance room makes it possible to connect with the acoustic neck certain frequencies of the intake noise Clear.
- FIG. 2 shows a detailed representation of the shape or Design of the acoustic neck.
- the housing is in the area of the resonance room divided into two and has a lower part 20 and an upper part 21.
- the opening 17 is provided for the clean air.
- Both in the lower part and in there are boundary surfaces in the upper part. These are the boundary surfaces in the lower part 22, 23 and in the upper part the boundary surfaces 24, 25.
- the boundary surfaces are designed so that they together form a rectangular Cross section 26 result, which is only indicated schematically here.
- the boundary surfaces or the rectangular cross-section is during injection molding by a appropriate core design created, with the core in the area of Breakthrough 27, 28 has a sideshift. There is a possibility that Arrange sideshift on the core part that forms the acoustic neck.
