Definitions
- the present invention relates to an oil filter device for an internal combustion engine according to the preamble of claim 1.
- the invention also relates to a filter cartridge with a cover for such a filter device and a cover for a filter cartridge.
- the present invention is concerned with the problem of providing an improved embodiment for an oil filter device of an internal combustion engine of the type mentioned, which is particularly characterized in that the exchange of the filter cartridge, the oil in the system does not have to be drained and replaced when replacing the filter cartridge anyway not get into the environment.
- the invention is based on the general idea, in an oil filter device for an internal combustion engine, which essentially comprises a support member and a filter cartridge screwed thereto to arrange the latter standing and to provide a drain system in the support element, which the running out of the filter cartridge residual oil when unscrewing the same reliably.
- the drainage system is designed in the form of an annular channel which encloses the filter cartridge in the screwed-on state. When the filter cartridge is screwed on, the channel is fluidically separated from a filter cartridge interior, whereas this separation is canceled when the filter cartridge is loosened.
- the channel is designed as an idling channel and, when the filter cartridge is detached, is fluidically connected to an oil reservoir, for example an oil collection tray.
- the invention thus offers the great advantage that on the one hand a previous draining the oil to replace the filter cartridge is unnecessary and on the other hand by the annular channel according to the invention still located in the filter cartridge residual oil is reliably collected so that it does not get into the environment and this can pollute.
- the channel is covered with screwed filter cartridge by sealant.
- the channel is protected from dirt and / or moisture, so that contamination of the channel can be avoided during operation of the filter device.
- This has the advantage that no dirt can accumulate in the channel, which is flushed when unscrewing the filter cartridge from then out of this exiting oil into the oil sump, thereby causing contamination of the oil.
- the sealing means comprise a cover which is held on the filter cartridge.
- the cover can be easily removed and screwed together with the filter cartridge and does not need to be removed or re-installed in an extra operation. This has a particularly favorable effect on the maintenance costs.
- the cover is rotatably mounted on the filter cartridge.
- a rotatable mounting allows a relative movement between the filter cartridge and the cover, whereby, for example, the cover is easy to position with respect to a predefined position to the carrier element.
- a cover designed as a collar has an inner contour which bears against the filter cartridge and has a latching contour which acts on the filter cartridge and engages in a complementary catching contour formed on the filter cartridge and wherein the counter-latching contour Fangsnut is formed and thereby allows a rotatable mounting of the collar on the filter cartridge via engaging in the circumferential groove locking contour.
- Such a locking contour on the cover or a counter-locking contour on the filter cartridge is a particularly simple way of axially fixed, rotatable mounting of the cover on the filter cartridge.
- this embodiment also allows the distribution of only one of the two components, whereby a particularly interesting for the spare parts business situation can be achieved.
- a reduction in waste is achieved because the cover, depending on the training, often has a longer life than the filter cartridge and therefore can be used longer and does not necessarily have to be replaced at the same time with the replacement of the filter cartridge.
- the carrier element has a first pure-channel connecting piece with an external thread and the filter cartridges a complementary thereto formed second pure-channel connection piece with an internal thread, wherein in the first clean-channel connection piece, the external thread-interrupting recesses are provided by which located in the filter cartridge residual oil during the Unscrew the filter cartridge from this can flow into the channel.
- the external thread-interrupting recesses are provided by which located in the filter cartridge residual oil during the Unscrew the filter cartridge from this can flow into the channel.
- the flow of oil thus begins already with the release of the screw and is most favorable if the complete unscrewing of the filter cartridge already finished, whereby a waiting time after unscrewing the filter cartridge for emptying the same can be avoided. As a result, the replacement time of the filter cartridge can be reduced and thereby the maintenance costs are reduced.
- the cover is made of plastic.
- such covers can be produced simply and inexpensively, for example by injection molding, and can be adapted to almost any shape requirement.
- a robust and durable cover can be created.
- FIG. 1 is a perspective view of an inventive oil filter device
- FIG. 2 is a perspective view of a support member of the oil filter device
- FIG. 4 is a view as in Fig. 3, but with screwed filter cartridge
- FIG. 5 is an enlarged sectional view of the area A of FIG. 4,
- Fig. 6 is a view of a cover according to the invention.
- an inventive oil filter device for example, for an internal combustion engine, a support member 2 and a connectable, in particular screw-on, and substantially cylindrical filter cartridge 3.
- the carrier element 2 is designed as a filter base and is preferably made of cast pressure, in particular die-cast aluminum.
- the filter cartridge 3 is arranged substantially standing above the support element 2. This makes it possible to exchange the filter cartridge 3 from above, which makes it unnecessary to lift a vehicle by means of a lift or to crawl underneath.
- an annular channel 4 is formed in the carrier element 2, which surrounds the filter cartridge 3 in the screwed state (see also Fig. 3 and 4).
- the carrier element 2 has a first pure-channel connecting piece 5 with an external thread and the filter cartridge 3 has a second pure-channel connecting piece 6 with an internal thread (see FIG. About the two clean channel connection pieces 5 and 6, the filter cartridge 3 is screwed to the support element 2.
- the channel 4 is circumferentially bounded by a channel circumferential wall 9, wherein the filter cartridge 3 is sealed / covered with respect to this channel peripheral wall 9 by sealing means 10.
- the sealing means 10 may comprise a cover 11, which is held on the filter cartridge 3.
- the cover 11 is preferably rotatably mounted on the filter cartridge 3.
- the cover 11 has on its inner contour, which rests circumferentially on the filter cartridge 3, an axially acting catch contour 12 directed towards the filter cartridge 3.
- the locking contour 12 engages in a complementary thereto formed on the filter cartridge 3
- Gegenrastkontur 13 which is for example formed as a circumferential groove, so that the cover 11 is rotatably supported on the filter cartridge 3 via the engaging in the circumferential groove 12 locking contour.
- the latching contour 12 is preferably designed as a latching ring or as a latching web. The interaction between locking contour 12 on the one hand and counter-locking contour 13 on the other hand not only secures the rotatable mounting of the cover 11 on the filter cartridge 3, but also fixes them in the axial direction of the filter cartridge 3.
- FIG. 3 shows the filter cartridge 3 in a state released or unscrewed from the carrier element 2, wherein the first clean channel connection 5 does not yet interact with the second pure channel connection 6.
- the seal 7 is also not yet on the sealing surface 8 of the support element 2, so that the channel 4 is still open.
- the cover 11 is latched via its latching contour 12 with the filter cartridge 13 and checks the channel 4th
- FIG. 4 shows the filter cartridge 3 screwed tightly to the carrier element 2, the seal 7 sealingly abutting the associated sealing surface 8 of the carrier element 2.
- the channel 4 is covered at the top by the cover 11 and thus reliably protected from contamination.
- this is unscrewed starting from the state shown in FIG. 4 by turning, with any upcoming residual oil volumes 14, characterized by correspondingly edged surfaces, when unscrewing the filter cartridge 3 in the channel 4 occur, and wherein in a further unscrewing the filter cartridge 3, the seal 7 from the associated sealing surface 8 solves and establishes a connection between the channel 4 and a flow channel 15, which is fluidly connected to an oil reservoir, not shown.
- a flow channel 15 which is fluidly connected to an oil reservoir, not shown.
- the external thread interrupting recesses 16 may be provided, through which oil during the unscrewing of the filter cartridge 3 can flow from this into the channel 4 (see Fig. 3).
- a stop may be provided on the carrier element 2, which prevents relative rotation of the cover 11 to the carrier element 2.
- the cover 11 can be formed in many different ways, wherein an embodiment is shown by way of example as a collar according to FIGS. 1 to 6. It is also conceivable, however, to design the cover 11 as a sealing ring arranged on the filter cartridge 3, which abuts the carrier element 2 on an inner side of the circumferential wall 9 when the filter cartridge 3 is screwed on, thereby sealing the channel 4 upwards. Furthermore, it is conceivable that the cover 11 or the sealing means 10 is formed as arranged on the peripheral wall 9 of the support member 2 sealing ring, wherein a sealing lip extends inwardly toward the filter cartridge 3 and sealing when screwing it to the support member 2 to the filter cartridge 3 invests. Regardless of the configuration of the sealing means 10, for example as a collar or as a sealing ring, it is always ensured that the channel 4 and the drain channel 15 are sealed up and thus pollution of the oil contained in the channel 4 and drain channel 15 can be avoided.
- the sealing means 10 or the cover 11 are preferably made of plastic, while the carrier element 2 is preferably made of die-cast, in particular die-cast aluminum.
- an exchange of only the filter cartridge 3 is possible while the cover 11 remains on the oil filter device 1 over several life cycles of the filter cartridges 3.
- a single cover 11 detached from the filter cartridge 3 is shown in FIG.
- the filter cartridge 3 should be replaced, which is initiated by unscrewing them from the carrier element 2.
- unscrewing the sealing ring 7 of the filter cartridge 3 is released from the sealing surface 8 on the carrier element 2 and thus opens a connection between the channel 4 and a drain channel 15.
- the channel 4 and the drain channel 15 is covered by the cover 11 and thus protected from contamination.
- the latching contour 12, which holds the cover 11 in the axial direction on the filter cartridge with the counter-latching contour 13, at the same time allows a relative rotation of the filter cartridge 3 relative to the cover 11.
- Screwing on the new filter cartridge is done in a similarly simple way, without the oil getting into the environment during the entire exchange process or leaving the system.
