Definitions

  • the invention concerns a filter device, especially a liquid filter, such as a fuel filter or oil filter, according to the preamble of claim 1 .
  • a filter device that is used as an oil filter or a fuel filter is disclosed in DE 197 46 752 A1.
  • the filter device comprises a hollow cylindrically embodied filter element that is secured on a radially inwardly positioned support structure and is flowed through by the fluid to be purified radially from the exterior to the interior wherein the filter interior forms an axial discharge passage for the purified fluid.
  • the filter element is framed by terminal disks at the end faces that have a central cutout for discharging the fluid from the filter interior.
  • a sealing ring is inserted that is supported on an inner housing wall and separates the axial discharge space from the inflow side of the filter element.
  • Such sealing elements are mandatorily required for a flow-tight separation of raw side and clean side.
  • the invention has the object to separate with simple means and in a space-saving as well as effective way the raw side from the clean side in a filter device.
  • the filter device has in a filter housing a hollow cylindrical filter element that is to be flowed through by the fluid to be purified in radial direction.
  • the interior of the filter element forms an axial flow space.
  • At one end face of the filter element there is a terminal disk where the sealing element is arranged.
  • this sealing element is injection-molded onto an axially projecting, annular socket that is connected to the terminal disk.
  • the stability of the filter device is improved because forces in the axial direction are transmitted substantially from the socket onto the filter housing.
  • the sealing element is positioned between the end face of the socket and the inner wall of the filter housing; since this section of the sealing element is however usually very thin-walled, a tilted positioning of the filter device that could lead to leakage flows is not to be expected as a result of the deformation of the sealing element.
  • the sealing element is comprised of an injection-moldable silicone material, in particular a fluorosilicone rubber (FVMQ) that is characterized by an excellent fuel resistance, in particular by excellent diesel fuel resistance and therefore in a special way is suitable for use in fuel filters.
  • FVMQ fluorosilicone rubber
  • the socket has shaped elements that contribute to an improved adhesion of the sealing material on the socket.
  • These shaped elements change the surface of the socket and are embodied as projections or, according to a preferred embodiment, as cutouts in the wall of the socket. In the embodiment as cutouts, they can be distributed uniformly about the circumference of the socket.
  • the sealing material will deposit on the shaped elements so that an additional resistance with respect to accidental removal of the sealing material from the socket is provided.
  • the cutouts are advantageously completely filled with the sealing material so that no leakage flows through these cutouts may occur.
  • the sealing material is expediently injection-molded onto the inner side, the outer side as well as the free end face of the socket so that the best possible sealing action is achieved. Even though, it is in principle sufficient to provide the sealing material only on the inner side or only on the outer side or optionally to provide the sealing material only on the end face of the socket or on a combination of end face and inner side or outer side of the socket.
  • the annular socket in its simplest embodiment is a cylinder whose side walls and free end face form the support for the sealing material.
  • other geometries may be provided also for the socket, for example, a socket with a cylindrically shaped section and a further section angularly extending therefrom or a socket with a slantedly extending wall that is positioned at an angle to the plane at the terminal disk.
  • the sealing material may extend either about the entire inner side and outer side of the socket or, according to a further embodiment, only across a partial area of the socket, for example, on the angularly projecting section of the socket.
  • two concentric sockets are provided that are spaced apart radially from one another wherein the sealing material is injection-molded onto both sockets. Since each one of the two sealing elements is provided with a sealing line, the sealing action is improved.
  • the socket is advantageously embodied as a monolithic part of the terminal disk; both components can be manufactured of injection-moldable plastic material. Basically, it is however also possible to embody socket and terminal disk as two separate components that are connected to one another
  • FIG. 1 a perspective view of the lower part of a filter device with a hollow cylindrical filter element whose end face is framed by a terminal disk that is provided with a central cutout for discharging the purified fluid, wherein the central cutout is surrounded by a socket onto which sealing material is injection-molded;
  • FIG. 2 a section view of the filter device according to FIG. 1 in the area of the socket;
  • FIG. 3 a section illustration of a further embodiment according to which two sockets concentrically arranged relative to one another are provided onto which sealing material is injection-molded, respectively;
  • FIG. 4 a further embodiment in which the socket has additionally an angularly arranged section that is a support for the sealing element;
  • FIG. 5 a further embodiment in which the socket is comprised of a slantedly extending wall that is formed monolithically with the terminal disk.
  • the filter devices illustrated in the Figures are suitable for filtration of liquid or gaseous fluids, in particular for filtering fuel such as diesel fuel or oil. Also, a use, for example, as an air filter is possible.
  • the filter device 1 illustrated in FIG. 1 comprises a hollow cylindrical filter element 2 in a filter housing 3 wherein the filter element 2 is flowed through radially from the exterior to the interior by the fluid to be purified so that the outer wall surface represents the raw side and the axial interior in the filter element represents the clean side from where the purified fluid is discharged axially through the end face.
  • the axial end face of the filter element 2 is framed by a terminal disk 4 that has a central cutout 5 that communicates with the axial interior of the filter element 2 .
  • a cylindrical socket 6 is inserted that advantageously is monolithically formed with the terminal disk 4 .
  • the socket 6 is a support for a sealing element 8 that is comprised of an injection-moldable material, in particular of a silicone material such as partially fluorinated liquid silicone (FVMQ) and is injection-molded onto the socket 6 .
  • the sealing material is located on the outer side, the inner side and the free end face of the socket 6 and covers also completely the cutouts 7 in the wall of the socket 6 .
  • the cutouts 7 have the function of shaped elements that ensure improved adhesion of the sealing material on the socket 6 .
  • the selection of the sealing material depends on the fluid to be purified.
  • the aforementioned material FVMQ is used that is characterized by high fuel resistance while at the same time providing excellent injection molding properties.
  • the socket 6 is formed monolithically with the terminal disk 4 .
  • the sealing element 8 has two contact lines: on the one hand, in the area of the free end face on the socket 6 and, on the other hand, at the transition area between socket 6 and terminal disk 4 on the side facing away from the central cutout 5 . In the area of the two contact lines the sealing element 8 has a greater wall thickness.
  • a circumferentially extending ring in the area 10 of the seal support a reinforcement ring can be provided. This ring is positioned circumferentially below or on the seal 8 .
  • high-strength sealing materials or sealing materials that have a high tear resistance are also be employed.
  • a second socket 9 is provided that extends concentrically relative to the first socket 6 but in comparison to the first socket 6 has a smaller diameter. Also, the axial extension of the second socket 9 is less than that of the first socket 6 .
  • the second socket 9 is also formed as a monolithic part with the terminal disk 4 as is the first socket 6 .
  • the sealing element 8 is injection-molded onto the first socket 6 as well as onto the second socket 9 and extends along the inner side of the first socket 6 , on the inner and outer sides of the second socket 9 as well as in the intermediate area on the terminal disk 4 between first and second sockets 6 and 9 . Moreover, the two free end faces of the sockets 6 and 9 are covered with sealing material.
  • both sealing lines are located in the area of the free end faces of the sockets 6 and 9 .
  • the cylindrical socket 6 in the area of its end face is provided with a section 6 a that is radially inwardly angled at a 90 degree angle whose free end face is a support of the injection-molded sealing element 8 .
  • the socket 6 that is a monolithic part with the terminal disk 4 is angularly embodied; it is positioned relative to the plane of the terminal disk 4 at an angle deviating from 90 degrees and is oriented radially outwardly.
  • the sealing element 8 that is injection-molded on the socket 6 engages the end face of the socket as well as the inner side and the outer side and has a relatively complex cross-sectional geometry. Two sealing lines are formed by means of which the sealing element 8 is seal-tightly supported on a further component of the filter device.
