摘要： The invention relates to an oil reservoir comprising an oil inlet pipe and at least one oil outlet pipe for connection to a hydraulic system. Said oil reservoir consists of a reservoir housing and a reservoir cover connected to the housing base and comprises an integrated oil filter. An oil filler pipe is configured on the housing cover, as is known from conventional oil reservoirs, and can be closed by means of a cap. At least one guide element is arranged in the reservoir housing and is fastened to at least one inner wall of the reservoir housing and forms a circular guiding track for the oil. Once the oil has entered the oil reservoir and has passed the oil filter arranged therein, it is forced by the guiding track to perform a rotational movement before leaving the oil reservoir. Any air that is possibly trapped in the oil is thereby separated and can leave the oil reservoir through an air outlet opening.

摘要： A filtering system (1), in particular for filtering liquids in internal combustion engines, has a filter element (4) through which a flow can pass in the radial direction and which is arranged in a filter housing (2) to be closed with a disk-shaped closure. The disk-shaped closure comprises two individual disks (6, 7) interconnected by a central flow pipe (8), the two individual disks (6, 7) and the flow pipe (8) forming a common plastic component.

摘要： A filtering system, in particular for filtering liquids in internal combustion engines, has a filter element through which a flow can pass in the radial direction and which is arranged in a filter housing. An overflow valve is arranged between the uncleaned side and the purified side of the filter element and is placed in the opening position when the pressure of the liquid on the uncleaned side of the filter element exceeds a threshold value. The valve body and the valve spring of the overflow valve are made of plastics.

摘要： The invention relates to a filter element, particularly for filtering liquids or gas, having a concentrically disposed filter medium folded in zigzag shape. The filter medium is equipped with front end disks at the front ends, which have an inner side connected to the filter medium, and an outer side, facing away from the filter element. At least one first front end disk has a valve element, which is disposed concentrically within the filter medium. This valve element is comprised of a valve seat, which is curved toward the outside across the level of the outer side of the end disk, wherein the valve element has a valve plate cooperating with the valve seat, which, surrounded by the filter medium, and is disposed inside at a first end disk in an axially movable manner.
