Filter-cooler combination for liquids, especially for the lubricating oil of a motor vehicle internal combustion engine

A filter-cooler combination for liquids, in particular lubricating oil of an automotive internal combustion engine, comprising the features

• the filter is designed as a screw-on cartridge (5) that contains inlet and outlet openings on an end face and can be detachably screwed onto a connecting element (1) having first connecting channels that are assigned to the inlet and outlet openings by means of a central thread and are directed at this end face,
• the connecting element (1) comprises the cooler (2) and has second connecting channels (14) for the inlet and outlet channels for the coolant, directed away from and outside of the filter-cooler combination and the fluid to be filtered has third connecting channels (7;
• 3, 4′),
• the connecting element (1) is detachably connectable to the base part with the assignment of the third connecting channels (7;
• 3, 4′) with respect to connecting channels of said base part carrying the connecting element (1),
• the connecting element (1) is detachably connectable to the base part by a tubular threaded connection (4), which is open on both ends and can be inserted into the connecting element (1), whereby said threaded connection (4) has
• at one end a first thread for screwing the screw-on filter cartridge (5) onto the base part,
• and at the other end a second thread for screwing on a connecting channel of the base part
• of the third connecting channels, permitting a total of two flows, one inlet and one outlet, one connecting channel is formed by the interior space (4′) of the threaded connection and the other is formed by a first annular channel (7) which is situated in an area of a connecting area of the connecting element (1) directly adjacent to the threaded connection (4) with which the connecting element (1) is put under tension on the base part by the threaded connection (4), whereby the two connecting channels (7, 4′) are surrounded by a peripheral sealing element (6) by means of which the two connecting channels (7, 4′) in the form of a ring gasket with a connecting element (1) stretched onto the base part are sealed toward the outside,
• comprising the features
• the first annular channel (7) communicates with the cooler (2) within the connecting element (1),
• the cooler (2) is designed in the manner of a known stacked-disk oil cooler,
• the stacked-disk area of the cooler (2) is situated next to the screw-on filter cartridge (5) in a plane perpendicular to the central axis of the screw-on filter cartridge (5) when the cooler (2) is connected to the connecting element (1),
• within the connecting element (1), a second annular channel (8) communicates with the oil outflow area of the cooler (2) through which fluid to be filtered flows and surrounds axially separated from the first ring channel (7).
