Definitions

  • the invention relates to a filter, in particular an air filter.
  • An air filter for motor vehicles is known for example from DE-PS 40 28 899.
  • This consists of a holder and a removable cover.
  • the bracket is provided with plug connections.
  • the cover part is inserted into these plug connections.
  • the filter insert is clamped between the two parts via sealing surfaces which are arranged on the holder and the cover part.
  • the plug connection is an elastically deformable element, which brings about a non-positive connection between the holder and the cover part.
  • a disadvantage of this device is the fact that - for example due to vibrations - the cover part can come loose from the holder and the filter housing thereby opens unintentionally.
  • the invention has for its object to avoid the disadvantages mentioned and to provide an air filter in which the filter insert is easy to replace, or the housing can be opened and closed easily and securely and can be produced with little effort.
  • This object is achieved on the basis of the preamble of the main claim by its characterizing features, by a filter, in particular for motor vehicles, consisting of a housing which is provided with a raw air inlet and a clean air outlet, a filter insert which can be inserted into the housing, the housing having at least one closure element has, which is firmly anchored to the housing, is created. This ensures that the housing connection is always secure,
  • An advantageous development of the invention provides that the housing and the closure element are made in one piece. This reduces the number of parts required and thus reduces the filter, which makes it inexpensive.
  • the housing consists of thermoplastic material. This makes the filter lighter and cheaper, and it can also be disposed of by type when the end of life has come.
  • the holder with its film hinges can be cast directly onto this housing.
  • the housing including the fasteners consists of a single part, which saves considerable assembly and manufacturing costs.
  • the housing consists of glass fiber reinforced plastic, this increases the strength of the housing, in particular for use in difficult terrain or other areas of application in which increased impact strength is useful.
  • closure element is designed as a toggle lever element. In this way, a defined closing with a closing force is possible.
  • closure element contains at least one film hinge. This proves to be advantageous since the housing together with the closure element can be produced in a single injection mold, and this also eliminates the need for additional screws or similar fastening means, which saves further weight and costs. 5
  • the closure element has position or path limiting elements. This measure ensures that the housing can be closed very precisely and in a defined manner, which is of interest with regard to the tightness or the entry of false air, since it prevents this.
  • closure element can be closed in a form-fitting manner, which guarantees that, in the event of use, even due to possible relative forces on the housing halves, these cannot be displaced relative to one another.
  • An advantage of the invention is the simple structure. An extra housing cover, which would require an additional injection mold, is no longer required. There are simple installation requirements.
  • Figure 1 is a partial view of the housing with the closure element
  • FIG. 2 shows a sectional illustration of the filter according to FIG. 1
  • the filter 1 shown in Figure 1 consists of a housing 2 with a raw air inlet 3, which is not shown in Figure 1 and a clean air outlet 4, which communicate with the intake system, not shown, of an internal combustion engine, also not shown.
  • a filter insert not visible in FIG. 1, which separates the raw air side with its raw air inlet 3 from the clean air side with its clean air outlet 4.
  • the housing 2 consists essentially of two halves, which are held together by means of a closure element 6 or can be opened and closed, in particular around the Install or remove the filter insert.
  • the closure element 6 consists of a toggle lever element 7, by means of which a firm locking connection can be established.
  • the closure element 6 includes two film hinges 8 and position or path limiting elements 9, which serve for a defined closing connection of the two housing halves and ensure that the housing sealing surfaces come to lie exactly on one another, so that the connection of the housing sealing surfaces 10 does not allow any false air to pass .
  • FIG. 2 shows a section through the filter 1 from FIG. 1.
  • the filter insert 5 is shown in this section.
  • This filter insert 5 consists of a zigzag folded filter medium, which is made in plate construction.
  • the filter 1 shown in Figure 2 consists of a housing 2 with a raw air inlet 3 and a clean air outlet 4 which is used in an internal combustion engine, not shown.
  • a filter insert 5 which separates the raw air side with its raw air inlet 3 from the clean air side with its clean air outlet 4.
  • the housing 2 consists of two halves which are held together with a closure element 6 and can be opened and closed.
  • the closure element 6 consists of a toggle lever element 7, by means of which a fixed locking connection is established.
  • the closure element 6 contains two film hinges 8 and position or path limiting elements 9, which serve for a defined closing connection of the two housing halves and ensure that the housing sealing surfaces come to lie exactly on one another, so that the connection of the housing sealing surfaces 10 does not allow false air to pass.
  • the entire air filter is characterized by a high level of maintenance friendliness, since the housing does not disintegrate into many individual parts after it has been opened.
