Definitions
- the invention relates to a fluid line with at least one resonator, in particular an air line, wherein the resonator has an inner part and an outer part and inner part and outer part are firmly and permanently connected to each other.
- Resonators in fluid lines have long been known and used to avoid unpleasant acoustic emissions during vibrations of the fluid in the fluid line.
- Today they are usually made of plastics, whereby mainly injection molded parts, but also blow molded parts are used. Injection molded parts have the disadvantage that their production is usually quite complex.
- blow molding is a relatively inexpensive production method, so that the use of blow molded parts is increasingly being sought.
- DE 102008016690 AI shows a generic resonator, in which both
- Resonator parts are formed as blow-molded parts. The parts each have a collar and are connected to these bonds airtight.
- the invention has for its object to provide a fluid line with a resonator of the type described in an improved embodiment that can be produced in a simple manner.
- the inner part of the resonator is formed as an injection molded part, which has at least two radial collars, which are axially spaced from each other and the inner part distributed on its radial circumference has openings
- the outer part is formed as a blow-molded part
- Inner part and outer part are inserted axially into one another such that no secondary air can flow through between the radial collars of the inner part and the inner surface of the outer part,
- Inner part and outer part are connected airtight to one another at a common, communicating axial end,
- Fluid in the fluid line in operative connection in operative connection.
- This solution according to the invention enables the use of cost-effective blow molded parts for the outer part.
- the blowing device for producing the outer part is independent of the remaining shape of the fluid line for all resonators of one type. Since an annular gap is not provided, the
- At least one further part of the fluid line is formed as a blow molded part, wherein the outer part of the resonator is formed as part of the further blow-molded part of the fluid line and integral therewith, and is arranged on at least one of the ends of the fluid line part.
- the outer part of the resonator is an integral part of the fluid line. A clamping or other connection to the said part of the fluid line is eliminated.
- Fig. 1 shows a fluid line according to the invention in a plan view
- Fig. 2 shows the resonator in a detailed view.
- FIG. 1 shows a fluid line 1 according to the invention.
- the fluid line 1 has a connecting piece 3 for connection to a further fluid-conducting component (not shown here).
- a resonator 5 is arranged at a second end 4.
- the fluid line 1 also has a holder 6 with mounting holes 7, which is welded to a stiffening web 8 and to the fluid line 1.
- the resonator 5 has a connecting piece 10, which also serves for connection to further fluid lines, not shown.
- the fluid line 1 has an outer tube 11, which is formed as a blow molding of a thermoplastic material. At its end 4, which is associated with the resonator 5, the outer tube 11 is widened in a region 12 radially with respect to the remaining outer tube 11.
- Figure 2 shows the resonator 5 such that the outer tube 11 is shown cut.
- the resonator 5 has, in addition to the widened in the region 12 outer tube 11, an inner part 14, which is also formed as injection molded part made of plastic.
- the inner part 14 has radially outwardly pointing collars 15 which are fitted in the flared part 12 of the outer tube 11 such that no gap occurs between the collars 15 and the outer tube 11, 12. Due to the arrangement of the inner part 14, Bunden 15 and outer tube 11, 12 are
- Resonance chambers 16 and 17 limited, wherein the resonance chamber 17 is limited except by a collar 15 by a final collar 18.
- the end collar 18 has a diameter which is greater than the diameter of the flared portion 12 of the outer tube 11 and is airtightly welded to the end 4 of the outer tube 11, 12.
- the inner part 14 has a plurality of openings 19 through which it is possible to a fluid, not shown here, flowing through the resonator 5, with the
- Resonance chambers 16 and 17 to communicate.
- the oscillation frequency of the fluid is displaceable, so that undesired acoustic effects can be reduced.
- the respective predetermined number and / or the axial distance of the collars 15 of the resonator 5 is very different
