State of the art

The invention relates to an oil filter system according to the preamble of claim 1.

It is known in the art to apply oil filters for internal combustion engines to a flange tightening. The flange has channels through which the oil to be cleaned up can flow to the oil filter. The crude oil channel in the flange terminates at the inlet of the Oil filter and the clean oil channel starts at the outlet of the oil filter. Thus, that too cleansing oil flowing through the flange into the oil filter is cleaned in the oil filter and then flows out of the oil filter in the flange.

Since the space is limited in motor vehicles, the additional parts such. Filter, Radiator or damper actuators are arranged in free spaces in the engine compartment. At this However, the required connections may not be available. Therefore, the accessories have complicated connections, e.g. Hoses, which are expensive and expensive. There is also the problem that tolerances of surrounding components require an individual adaptation of the additional parts, to avoid leakage or voltage. This measure is very expensive. Furthermore, there are problems with filters, especially in liquid filters Sealing the connections, which is why expensive, dimensionally stable materials are used have to.

The object of the invention is therefore to provide an oil module, which is inexpensive in the production and easy in the assembly is. This task is characterized by the features of claim 1.

Advantages of the invention

The oil module according to the invention can easily be used in confined engine spaces and unfavorable Be arranged. This unfavorable for the oil module installation space exists in internal combustion engines in a motor vehicle, in particular in internal combustion engines with two parallel cylinder banks in V arrangement. The oil module has a housing and a receiving plate. In the housing, various oil treatment units, such as e.g. Heaters be arranged. Oil treatment units are components to understand which change the oil in its chemical or physical properties. The housing is on the internal combustion engine or to those surrounding the internal combustion engine Fixed components, with no direct connections available at this point are. The housing has an inlet and an outlet, whereby the oil passes through the inlet can flow into the housing and can flow out through the outlet again. The inlet and the outlet are designed as pipe sockets, with both inlet and also outlet can be integrated into a single pipe socket. The pipe socket is for bridging distances, this being e.g. as flexible hose line or may be formed as a rigid tube. In training as flexible Hose line may be provided in its end a connector. At a Training as a rigid pipe, the pipe socket can be made in one piece with the housing be. The pipe socket is connected to a nozzle receptacle, this connection is oil-tight and movable within specified limits. The nozzle holder is on one Receiving plate arranged, which via a first oil passage for the treatment Having oil and a second oil passage for the treated oil. The first oil channel is with connected to the inlet of the housing and the second oil passage is connected to the outlet of Housing connected. The receiving plate may e.g. directly on an engine block or be arranged his attachments.

Both the housing, as well as the receiving plate are fixed to the internal combustion engine or arranged on surrounding components. The mounting location of the mounting plate and of the housing are spaced apart, wherein the mounting planes also to each other are spaced. The mounting planes preferably run parallel to one another, wherein there is a height difference between the mounting planes. By the Tolerances of the internal combustion engine or the surrounding components are the Housing and the receiving plate always in a slightly different position to each other. The Position varies from one internal combustion engine to another, but can also be due Temperature differences and the associated thermal expansion slightly change. The tolerance compensation between the housing and the mounting plate takes place in the connection between the pipe socket and the nozzle holder, so that neither the housing nor the mounting plate is damaged by tensions. By the separation of the housing from the receiving plate can the material selection such be made that the appropriate material are selected for each site can. Here, a higher quality material can be used for the receiving plate be because there are larger temperatures and higher pressures at the receiving plate. For the housing, a cheaper material can be selected because the housing has a pressure-compatible geometry and cylindrical in advantageous embodiments is executed.

The two pipe sockets can e.g. at the same level be arranged in the housing and lead to the same plane on the receiving plate. Here, the nozzle recordings are also arranged on the same plane. Furthermore, it is possible the pipe socket at different levels on the housing to be arranged and parallel to each other to different levels of the receiving plate to let go. With this configuration, the oil module is also in difficult installation situations customizable.

It is advantageous that the pipe socket has a sealing groove in which a Seal, in particular an O-seal, is arranged. This seals the seal in one fixed axial position on the pipe socket and can not slip. The seal corresponds to the nozzle receiving and thus creates the sealing connection, wherein the seal can compensate for tolerances.

In a further embodiment of the invention, a circumferential is on the pipe socket Dirt collar arranged. The dirt collar is designed such that it receives the nozzle protects against dirt. In this case, the dirt collar can e.g. when be circumferential annular disc which connects to the nozzle receiving and thus prevents the ingress of dirt into the nozzle receptacle. For others Embodiments, the Dirt Collar made of a flexible material and on the one hand connected to the pipe socket and on the other hand with the nozzle holder be. Furthermore, a hollow geometry is conceivable, which partially the nozzle holder overlaps. Here, the hollow geometry has a free space in which the nozzle receiving, without being able to hit on the side walls, can protrude.

According to a further embodiment of the invention, the nozzle receptacle over a securing area in which a securing element engages and the pipe socket captively secured to the nozzle holder. Here, the fuse element e.g. a snap hook, which is arranged on the pipe socket and in, as Eyelet configured security area engages, with several snap hooks can be provided.

An advantageous embodiment provides that the securing element is a clip, which is inserted through the securing area and fixes the pipe socket. Here, the securing area is formed by a groove in the nozzle wall through which the clamp up to the, arranged in the nozzle receiving, pipe socket engages and fixed it to the designated webs.

According to one embodiment of the invention, the pipe socket of the inlet and outlet fixed with a common clamp. As a result, during assembly, a single fuse element required, which secures both connections.

In a particular embodiment of the invention, a filter element is in the housing arranged, whereby the oil module is an oil filter module, which cleans the oil.

In an alternative embodiment, an oil cooler is arranged in the housing, whereby the oil module is an oil cooler module that cools the oil. In further embodiments Both a filter element and an oil cooler in the same housing be arranged, whereby the oil module fulfills both functions, cooling and cleaning.

According to one embodiment of the invention, the housing made of plastic, wherein Verschraubungsbereiche are provided, to which the housing to the internal combustion engine is attached. In this screwing a sleeve is arranged, which is preferably made of metal. Since metal does not creep, unlike plastic, the housing can be permanently screwed securely on the internal combustion engine. The Sleeve has an inner diameter which is larger than the outer diameter a screw inserted through the sleeve. Thus, the screw has in the sleeve Game, whereby the housing can be aligned on the internal combustion engine. The Mounting plate is made of metal and can thus higher loads, such as Temperature and pressure, withstand.

In alternative embodiments, the housing may be made of metal and the receiving plate be made of plastic. Such a material combination can be high mechanical Strains such as e.g. occur in a motor vehicle accident, withstand, whereby the oil in the housing can not escape.

These and other features of preferred embodiments of the invention are excluded from the claims also from the description and the drawing, wherein the individual features in each case alone or in the form of sub-combinations realized in the embodiment of the invention and in other fields can be and represent advantageous and protectable versions for which protection is claimed here.
