Definitions

  • the invention relates to an air connection unit for an air filter housing having at least one nozzle, in which at least one maintenance interval display or a maintenance switch connection is integrated and which is rotatably mounted in a recess in the air filter housing, and with an adjoining the nozzle air line element.
  • Air filters are supplied via air ducts, e.g. Pipes or hoses connected to the intake system.
  • the disadvantage here is that integrated maintenance switch terminals are always in the same, fixed position. Also results in the use of angled ports always a fixed relative nozzle position between raw air and clean air.
  • corrugated pipes are corrugated pipes as well as pipes with a corrugated geometry which allows bending without buckling or constriction of the pipe jacket.
  • the position of the maintenance switch connection can be freely selected.
  • the position of the clean air connection can be selected independently of this. As a result, the position, length and angle of the connection are freely selectable.
  • the air duct element or parts thereof are a flexible wiring even in limited space, e.g. in an engine compartment, possible.
  • the system is insensitive to possible tolerances of the distances to the components to be connected or their location. Regardless of whether the position or the distance varies, the movable connecting piece can be connected to the suction system with little effort.
  • the angle section formed as a corrugated tube of the air duct element should include an angle of 45 ° to 150 °, in particular 90 ° in the force-free state. Due to the flexibility of the corrugated pipe area most simple deflections of the air duct element can be realized.
  • the air duct element preferably terminates in a connection collar. This is an end-side paragraph, around which a hose clamp can be placed, with which the connection collar can be pressed firmly onto a connecting piece.
  • the configurations described in this way apply in the initial state without force.
  • the corrugated pipe sections can be either permanently bent from this or bent back resiliently in order to adapt to the provided conduction path in an engine compartment.
  • an additional connecting element for fastening the air duct element at an additional point in the engine compartment can be provided on the connecting collar located between the angle sections.
  • a configuration can be manufactured and delivered, which allows multiple deflections, but can also be cut off directly behind the central connection collar as needed, if only a simple deflection is needed.
  • the additional cost of the additional angle portion are so small in a blow molded plastic part that it may be economically advantageous to offer this section from the outset to the customer, as to produce two different types of air connection units, distribute and stock for spare parts needs.
  • the air duct element does not need for adaptation be severed more. It can rather be subtracted the unneeded second angle section.
  • FIG 1 shows sections of an air filter housing 20 with an air feed port 22, which is shown in this figure as well as in the following figures 2 and 3, to indicate that the position of the air filter housing 20 in all figures is unchanged.
  • it is a cylindrical air filter housing for a round filter, which has a central recess on a receiving flange 21 on the clean air side, to which an air connection unit can be connected to the air filter housing with other modules in an engine compartment, for example with a suction module an internal combustion engine, to connect.
  • a nozzle 11 is inserted in the receiving flange 21, a nozzle 11 is inserted. A part of the nozzle 11 is in the receiving flange 21st or received in the air filter housing 20 and there so locked or secured in any other way, that although a twisting is possible, however, axial tensile forces can be absorbed at the nozzle.
  • a maintenance switch terminal 12 is arranged in the protruding part of the nozzle 11. This is a branch of trained within the nozzle
  • Air line to be able to lead a thin hose line to a more distant pressure sensor. It is also possible to arrange a suitable sensor for measuring a pressure drop due to contamination of the air filter directly on the nozzle 11.
  • the connecting piece 11 is adjoined by an angle section 14 which is deformable via a fold geometry so that the center axis at the end, which is designed as a connection collar 15 for receiving a hose clamp, is at an angle of approximately 45 ° relative to the center axis of the connection piece 11 ° can be employed.
  • Figure 2 shows the same embodiment of the air connection unit 10, in which the nozzle 11 is rotated relative to the position in Fig. 1 so that the maintenance switch terminal 12 is above.
  • the independent of the position of the nozzle 11 twistable air duct element is bent with its connection collar 15 by 90 ° downwards.
  • FIG. 3a shows a second embodiment of an air connection unit 10 ', in which the air duct element comprises two angle sections 14', 16 ', which are connected to one another at a central connection collar 15'. There, an additional attachment can be attached. The connection with further modules takes place at the connection collar 17 'at the end of the second angle section 16'.
  • the second angle section 16 ' is not needed, it can be separated along the dot-dash line in Fig. 3a.
  • connection collar 15 ' is like the end-side connection collar 17' formed and can therefore be connected via the same fasteners with further leading components.
