    • The invention relates to a liquid filter, for example an oil filter for cleaning lubricating oil, especially for use in internal combustion engines of motor vehicles. A ring-shaped filter insert separates an unclean side from a clean side in the interior of the liquid filter. A metal filter housing comprises a first flange with which the liquid filter can be screwed to a component via a screw connection, said component having an inlet for uncleaned liquid, an outlet for cleaned liquid and a relatively pressureless idle duct. The first flange contains an axially acting outer seal that includes inlet, outlet and idle duct, and a carrier receiving compartment encircled by the outer seal. A functional carrier insert is inserted in the carrier receiving compartment and is provided with an inlet compartment open towards the inlet, an outlet compartment open towards the outlet, and a idle duct compartment open towards the idle duct, the individual compartments being sealed from one another by axially acting inner seals. The screw connection with which the first flange is screwed to the component acts in the axial direction and axially forces the axially acting seals against the component, while the functional carrier insert rests on the first flange.
    • 本发明涉及液体过滤器,例如用于清洁润滑油的油过滤器,特别是用于机动车辆的内燃机中。 环形过滤器插入件将不洁净侧与液体过滤器内部的干净侧分开。 金属过滤器壳体包括第一凸缘,液体过滤器可通过该第一凸缘经由螺纹连接件拧到部件上,所述部件具有用于未清洁液体的入口,用于清洁液体的出口和相对无压力的空转管道。 第一凸缘包括轴向作用的外部密封件,其包括入口,出口和空闲管道,以及由外部密封件包围的托架接收隔室。 功能性载体插入物插入载体接收隔室中并且设置有朝向入口敞开的入口隔室,朝向出口开口的出口隔室和朝向空闲管道打开的空闲管道隔室,各个隔室彼此密封 通过轴向作用的内部密封。 与第一凸缘螺纹连接在组件上的螺纹连接件沿轴向作用,并且轴向作用的密封件抵靠在部件上,同时功能性载体插入件搁置在第一凸缘上。
