  • State of the art
  • It are known replaceable filter, soft over a arranged in a housing Have filter element. The filter element is used for the deposition of impurities Liquids. The housing has one Lid and a pot, which are sealed together. In the case are inlets and outlets arranged, through which the liquid to be purified in the replaceable filter on or out of the replaceable filter can flow out. On the housing is a seal arranged through which the replaceable filter sealing connected to a flange. The seals have generally over a rectangular one Cross-section, which is inserted in a seal receptacle in the housing becomes. When installing the replaceable filter, the seal between the housing and the flange is pressed, whereby the seal is produced. Because the seal over the housing survives, comes the seal to rest against the flange before the replaceable filter is attached to the flange with sufficient torque. To attract the replaceable filter with sufficient torque, kick big shear on the seal, which can lead to damage to the seal.
  • Farther There is the problem that cracking occurs at extremely high torques can come in the connection area between the pot and the lid.
  • task The invention is to provide a replaceable filter which is simple is in the handling and avoids the disadvantages mentioned above. This object is solved by the features of claim 1.
  • Disclosure of the invention
  • Of the inventive replaceable filter is used to clean liquids especially of oil in internal combustion engines. The replaceable filter has a housing with an inlet and a Outlet. In the case a filter element is arranged such that the inlet sealing is separated from the outlet. The filter element has a filter medium, soft z. B. cellulose-based or of a synthetic non-woven fabric can exist. The filter medium can be zigzag folded and closed annular and be closed at the formed end faces with end plates. In other embodiments, the filter medium can also directly with the housing be connected. The housing can be formed by a pot and a lid, the lid sealingly connected to the pot. This can be the pot of a any material, in particular metal or plastic, exist. In the same way, the lid can also be made of metal or plastic be made. The connection between the pot and the lid can z.

The housing has one Seal receptacle for receiving the seal, wherein the seal receptacle may be formed in the form of a groove. In other embodiments are heels or corresponding geometries on the housing provided to the seal at one for it to fix the intended position. The seal has a Sealing area and a damping area, wherein the sealing area insoluble with the damping area connected is. The sealing area is designed such that this Part of the seal is sealingly pressed against an attachment. For this purpose, the sealing area has a Hardness of z. B. 60 Shore A. The required hardness of the sealing area is can be adapted to the respective mounting pressure, therefore, hardening of z. B. 40 to 80 Shore A can be used. At lower assembly forces is make the sealing area softer. For larger assembly forces is the sealing area accordingly harder to choose. Of the attenuation range is characterized by a relatively hard material of z. B. 85 Shore A formed, this material attaches to the attachment, but in the ruling assembly workers is not compressed. According to the assembly forces can the damping range over a Hardness of about 75 to 100 Shore A have. By creating the damping area learns the sealing area has a defined compression on the installation component, making a reliable Seal is generated.

Through the unsolvable connection the sealing area with the damping area ensures an exact positioning of the areas to each other, whereby the assembly is considerably simplified.
  • According to one advantageous development of the invention is the seal in the 2K process produced. The harder ones Material component forms the damping area and provides the basic framework the seal. The second material component, which consists of a softer material is formed directly with the first material component connected or molded directly to the material component. Consequently the seal is easy to produce. Preferably, a thermoplastic becomes Plastic, a foam or an elastomer used.
  • It is advantageous that the sealing area between two damping areas is arranged. Here are an annular inner damping area and a ring-shaped Outside attenuation range formed, and the sealing area is also located as an annular area between the two damping areas. Here, the ring shape may be formed as a circular ring shape. Of course, too other ring-shaped closed geometries conceivable, in particular oval or elliptical Geometries. Due to the arrangement of the sealing area between the cushioning Zones is an optimal introduction of force allows, with the sealing area between the damping areas is compressible.
  • at an alternative embodiment, the damping range between two Arranged sealing areas. Here, the annular damping region of an inner Sealing area and an outer sealing area surround. By the use of a single damping range comes the attenuation range annular on the plant component to the plant and the individual sealing areas can accordingly be pressed, with larger bumps can be compensated on the investment component.
  • at In a particular embodiment of the invention, the sealing region has a Cross section having a circle segment. Preferably the axially over extending the damping area Sealing area designed as a quarter or semicircle. Of course you can the circle segment also all Occupy intermediate areas. The circle segment cross-section of the sealing area goes subsequently with flowing Contours in the damping range over, causing a reliable connection is generated.
  • at an alternative embodiment, the sealing region has sealing lamellae, which extend in the unmounted state axially over the damping region. During assembly, the lamellas seal against the installation component and thus produce a reliable Seal between the replaceable filter and the plant component.
  • According to one advantageous embodiment of the invention, the damping region has a flat Contact surface, which is attached during assembly plan to the plant component. Due to the flat contact surface an optimal transmission takes place the assembly staff from the case of the replaceable filter on the corresponding investment component.
