The invention relates to a liquid filter, especially an oil filter, for cleaning lubricating oil, especially for internal combustion engines of automobiles, comprising an upright filter housing which contains a receiving area for a ring-shaped filter insert that is inserted into said receiving area, an inlet channel for unclean liquid, an outlet for clean liquid, and an additional discharge channel which is exposed when the ring-shaped filter insert is removed. An eccentrically projecting pin is moulded to a lower end plate and sealingly penetrates an opening of the discharge channel when the ring-shaped filter insert is introduced into the filter housing. According to the invention, a ramp is configured on the floor of the receiving area and is positioned in such a way that when the ring-shaped filter insert is introduced into the filter housing, the pin lies on said ramp and when the ring-shaped filter insert is rotated about its longitudinal axis, the pin slides downwards along the ramp and enters the opening of the discharge channel at the lower end of the ramp. This improves handling.

A ring filter element comprising a plug for, in particular, a lubricating oil filter of an internal combustion engine. Said ring filter element is provided for insertion into a filter housing comprising a filter housing pot and a filter cover that can be axially detached. When inserted in the closed filter housing, the plug seals an opening which is provided in the filter housing pot and which extends in the same axial direction as the plug. The aim of the invention is to provide a ring filter element of the aforementioned type that can be packed in a space-saving manner. To this end, the ring filter element comprises the following characteristics: the plug is mounted on the ring filter element in such a manner that it can be displaced along to same axis or parallel to the axis, and; said mounting permits the plug to move with the aid of an actuating means which acts, by contact, upon the lug from outside the ring filter element.

The invention relates to a especially an oil filter for cleaning lubricating oil, especially for internal combustion engines of automobiles, comprising a filter housing which is positioned essentially upright when installed, which contains a filter receiving area for accommodating a ring-shaped filter insert in an upper section and which contains an inlet channel for unclean liquid, which connects a supply line of the liquid filter to an unclean side of the ring-shaped filter insert in the filter receiving chamber and an outlet channel for clean liquid, which connects a clean side of the ring-shaped filter insert in the filter receiving area to a discharge line of the liquid filter, in a lower section. The invention provides for a functional support insert which can be inserted into the support receiving area formed in the lower section of the filter housing and which contains the outlet channel, in order to simplify the production of the liquid filter.

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.
