Abstract: A ring filter element is provided for a liquid filter, especially for an oil filter for purifying lubricating oil, especially for an internal combustion engine of a motor vehicle. The ring filter element comprises a filter material which is arranged in an annular manner and at least one end disk comprising an outwardly protruding journal which is eccentrically arranged in relation to the longitudinal central axis of the ring filter element. The functionality of the ring filter element can be improved by providing a discharge channel which radially penetrates the journal and the associated end disk next to the filter material.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a liquid filter (1), 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 (2) comprises a first flange (3) with which the liquid filter (1) 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 (3) contains an axially acting outer seal (24) that includes inlet, outlet and idle duct, and a carrier receiving compartment (22) encircled by the outer seal (24).

Abstract: An oil filter 1 for an internal combustion engine includes a filter body 3 and a plastic filter housing 2. Integrally formed within the filter housing, a safety wall 7 is radially fitted around the feed channel 4 and the return channel 5 creating a collecting space 6 that surrounds both channels. If seal leaks occur when the device is connected to a flange, e.g. of an engine block, the leaked oil will accumulate in the collecting space.

Abstract: Disclosed is a heat exchanger comprising superimposed heat exchanger plates (, 2'), a collar (4), fluid connectors (12), connecting holes (5) and fastening means which present at least one passage (15) comprised of holes (6, 27) in alignment towards each other in the plates (2, 2'), through which a tension rod (16) can be passed. One end of the tension rod (16) rests upon the connecting plate (26) or the plate (2, 2') adjacent thereto. In the hole (6, 27) alignment area, each thermal plate is tight relative to the adjacent plate (2, 2').

Abstract: A snap-lock connection for two parts (1, 2) which canrotate in relation to each other has radially resilient locking hooks (3) arranged in a ring, supported on the ring-shaped edge of a matching body and secured against unlocking in the radial direction by a fixing ring (6). The fixing ring (6) and/or the body that form the ring-shaped edge (5) are designed as a ring which is secured to one of the parts (1, 2) exclusively by individual webs (7) spaced apart around its circumference.

Abstract: An oil filter has a cap screwed to the approximately upright arranged filter housing of the oil filter for the cleaning of lubricating oil, with a ring-shaped filter insert being detachably fastened on the cap and separating the outer inflow space from the inner flow-off space. In the lower zone of the filter housing, provision is made for a valve-like acting member, which is automatically opened with each change of the filter insert and serves for discharging oil that remained in the filter housing into an oil-collecting space via a discharge duct. A center bar is rotatably connected with the cap. The center bar is axially displaceable in a limited way and has in its zone close to the cap a piston-like flange, which is sealed against the filter insert and separates the inflow space from the flow-off space. The center bar has, in its lower end zone, the valve-like acting member cooperating with the discharge duct.
