Abstract: The oil container comprises a housing formed by a lower oil sump (1) and an upper housing closure, a sealing (2) arranged between the oil sump and the upper housing closure, an integrated oil filter received from the housing, a filter housing formed from a filter lower shell (3) and/or a filter upper shell (4), and a filter medium (5) received from the filter housing. The housing wall of the oil-container housing formed by the oil sump and the upper housing closure is made of metal and the filter housing is made of plastic. The oil container comprises a housing formed by a lower oil sump (1) and an upper housing closure, a sealing (2) arranged between the oil sump and the upper housing closure, an integrated oil filter received from the housing, a filter housing formed from a filter lower shell (3) and/or a filter upper shell (4), and a filter medium (5) received from the filter housing. The housing wall of the oil-container housing formed by the oil sump and the upper housing closure is made of metal and the filter housing is made of plastic. The filter housing of the oil filter integrated into the oil container is secured at the inside of the housing wall of the oil-container housing. The filter housing is secured by a welding connection to the housing wall of the oil-container housing. A metal inlay is inserted into the filter housing at the outside contour, which is partially molded with the plastic of the filter housing or partially contained by the plastic of the filter housing, where a surface section welded with the housing wall of the oil-container housing consists of plastic. The upper housing closure of the oil-container housing is formed by a function group of a device equipped with the oil container, where the oil container is flange-mounted on the device. The oil-container housing consists of aluminum. The metal inlay is formed as a stripe-forming element that comprises the surface section welded with the filter housing and oil-container housing, on a side, which is turned to the interior surface of the housing wall of the oil-container housing. The filter lower shell or filter upper shell in which the relevant metal inlay is inserted consist of plastic that is transparent for light of lasers serving the welding of the surface section of the metal inlay freely held by plastic with the oil-container housing. The metal inlay is inserted in a footpath forming on the filter housing and the relevant metal inlay comprises a section welded with the filter housing, where the section is freely held on the side turned to the oil container housing as also on the side of the plastic. A window is formed in the corresponding footpath of the filter housing on the side turned away the oil-container housing. The light of the laser is applicable for welding the metal inlay with the oil-container housing over the window. The surface section freely held by the plastic at one side or the section free from plastic at both sides is formed in an area bent in the direction of the oil-container housing to be welded at both axial ends with the metal inlay. The filter housing is formed as a multi-functional function carrier. A reception is formed on the filter housing for a permanent magnet serving metallic particles containing the solid contents in oil. A hook-shaped element for clipping the sealing to be inserted between the oil sump and the upper housing closure of the oil-container housing is formed on the filter housing. A thread bushing for an oil drain plug molded with the plastic of the filter housing is inserted into the filter lower shell or into the foot path. The thread bushing is made of brass.
