  • the invention also relates to a motor vehicle with an internal combustion engine having such a filter device.
  • the invention also relates to a closure element for temporary sealing of an opening of a body / volume filled without pressure, preferably a filter device.
  • an oil filter to a radiator eg JP2-1147110
  • Such coolers can be cooled by means of a liquid, then they are attached as a combination module with the filter in the test phase of internal combustion engines on the engine, on the other hand they can be air cooled, then they are usually not on the internal combustion engine, but on the body of the vehicle attached and are connected only after the test phase with the filter device during installation of the internal combustion engine with this. In a cold test, cooling of the internal combustion engine is not required.
  • the filter device is also essential for short-term operation, since in the production resulting metal chips must be filtered out from the beginning of the engine oil.
  • the present invention addresses the problem of providing a filter device in which no engine oil escapes during storage and transport.
  • the invention is based on the general idea of providing in each case a closure device in an inlet / outlet of a filter device for an internal combustion engine oriented in the direction of a cooler device, which opens the associated inlet / outlet openings or channels of the filter device oriented in the direction of the cooler device, provided the filter device is connected to the cooler device and closes, if such a connection of the filter device to the cooler device is not yet done.
  • a closure device in an inlet / outlet of a filter device for an internal combustion engine oriented in the direction of a cooler device, which opens the associated inlet / outlet openings or channels of the filter device oriented in the direction of the cooler device, provided the filter device is connected to the cooler device and closes, if such a connection of the filter device to the cooler device is not yet done.

  • the filter device has an inlet / outlet oriented in the direction of the internal combustion engine and the above-mentioned inlet / outlet oriented in the direction of the cooler device, the closure device according to the invention being provided only in the latter inlet / outlet.
  • the closure device With the closure device according to the invention, it is possible to operate the internal combustion engine during a test phase, for example on an engine test bench, without connection to the cooler device, wherein for operating the internal combustion engine in the test phase, the filter device arranged on the internal combustion engine is provided. Since the closure device is designed in such a way that, when the inlet / outlet (inlet / outlet channels, or openings) is closed in the direction of the cooler, there is a bypass through which the filter device flows, one may also be required for the test run of the internal combustion engine Oil filtration done easily.
  • the internal combustion engine together with the filter device can be connected to the radiator via its inlet / outlet oriented in the direction of the radiator, wherein during the connection to the radiator, namely by inserting radiator-side connecting pipe into the inlet / outlet Channels of the filter device, the closure devices are moved and the inlet / outlet openings are opened.
  • the opening of the inlet / outlet of the filter device oriented in the direction of the cooler device only takes place at a point in time at which the filter device is already connected tightly to the connecting piece of the cooler device.
  • the closure device is designed as a closure element, which is mounted like a piston in the one cylinder forming in the direction of the radiator device oriented inlet / outlet of the filter device slidably.
  • a trained closure element can be easily, for example.
  • the closure device embodied as a closure element seals the inlet / outlet of the filter device oriented in the direction of the cooler device and at the same time forms a bypass through which the filter device flows, so that, for example, an oil circuit through the filter device during the relatively short test phase of the Internal combustion engine is given.
  • opening of the inlet / outlet of the filter device oriented in the direction of the cooler device only takes place at a point in time at which the connecting pieces of the cooler device are already introduced tightly into the inlet / outlet of the filter device oriented in the direction of the cooler device, so that an undesired exit Of engine oil can be reliably avoided.
  • a filter device 1 is attached to an internal combustion engine 2 and communicating with it, so that, for example, can be done by the filter device 1, a cooling of engine oil.
  • the filter device 1 Not connected according to the Fig. 1 the filter device 1 to a cooler device 3.
  • the according to the Fig. 1 illustrated state corresponds, for example, that of a test phase of the internal combustion engine 2 on a test bench, in which a filtration of the engine oil is required.
  • the filter device 1 can be connected to the cooler device 3 via an inlet 4 oriented in the direction of the cooler device and also a drain 5 oriented towards the cooler device on the filter device 1.
  • connecting pieces 6 and 7 are provided, wherein intervenes in connected to the cooler device 3 filter device 1, the connecting piece 6 in the sequence 5, while the connecting piece 7 engages in the inlet 4 of the filter device 1, or vice versa, depending on the structure of the cooling device 3 and the filter device.
  • a closure device 8 is respectively provided in the inlet 4 oriented in the direction of the cooler device and the outlet 5 oriented in the direction of the cooler device 10, for example, in the form of a closure element 11 or 12 provided (see. Fig. 3-5 ).
  • a through-flowing through this bypass 9 is possible. Wherein the use of this bypass 9 can be controlled when mounted on the cooler device 3 filter device 1 targeted when needed.

  • An axial longitudinal extent of the respective closure element 11, 12 is chosen so that that it comes into contact with the associated cooler-side connecting piece 6, 7 and can be adjusted by the latter via the guiding / supporting device 15 into a position which opens the associated inlet / outlet 4, 5 of the filter device 1.
  • Fig. 3 It is shown how the closure elements 11, 12 can be introduced before the attachment of the filter device 1 to the internal combustion engine 2 in the inlet / outlet 4, 5.
  • Fig. 4 it is shown that the radiator-side connecting pieces 6 and 7, although on the guide / support means 15 of the associated closure elements 11, 12 abut, but not tightly in the respective associated inlet / outlet 4, 5 engage. For this reason, the two closure elements 11, 12 are still in an in the direction of the cooler oriented inlet / outlet 4, 5 occlusive state.
  • the cooler side connecting piece 6, 7 are inserted into the respectively associated inlet / outlet 4, 5, as for example, according to the Fig. 5 is shown, they press the each in the inlet / outlet 4, 5 plugging closure element 11, 12 deeper into the respective inlet / outlet 4, 5 and thereby into a respective inlet / outlet 4, 5 opening state.
