A separator for liquid, in particular for removing oil from crankcase gases, having a cover ( ) into which a mount ( ) for a cylindrical separating cartridge ( ) is incorporated. The separating cartridge is composed, for example, of a non-woven separating material ( ) wound around a support body ( ) having end plates ( ) on the end faces ( ) of the support body. The end plates ( ) may be composed, for example, of a two-component synthetic resin material. This results in a stable component which can be sealed utilizing the elasticity of the end plate ( ) when pushed into the mount ( ). This results in a cost effective exchangeable part in which several seals are saved in the complete structural component and yields a structural unit having increased economic effectiveness.

Separator for liquids comprising a separating cartridge, particularly for separating oil from crankcase gases

A filter element for an air filter, including a filter insert (,) and a seal (,) extending around the outer edges of the filter insert on the flat side thereof; the filter insert being folded in a zig-zag or pleated form and being composed of filter paper or filter fabric. The filter element (,) rests against parts of a filter housing through the seal (,). The folded filter insert has a contour on one side which deviates extensively from a plane, at least in certain predetermined areas, thus creating a continuous zig-zag fold.

Filter element for an air filter and a method for the production thereof

The invention concerns an intake system, in particular an intake pipe of thermoplastic plastics for the intake air of an internal combustion engine with in particular cylinder rows arranged in a V-shape. The intake system comprises at least two elements (,), the first element (,) having a substantially closed shape and simultaneously forming the lower half-shell of the intake pipes. The second element (,) is designed as the upper half-shell of the intake pipes and is connected to the first element (,) by the plastics welding technique.

An air filter, especially for the intake air of an internal combustion engine, including a housing (,) with a filter insert (,). The housing includes a raw air inlet (,) and a clean air outlet (,), as well as an opening (,) for introduction of the filter insert (,). The filter insert (,) is included of a supporting element (,) and a filter element (,) and can be positioned in contact with a sealing surface with a sealing element or gasket (,) interposed therebetween. The housing (,) includes a supporting element (,) for the filter insert (,), and the filter insert (,) can rock or pivot relative to the supporting element (,) and reaches its final position through such a pivoting or swiveling movement.

Filter for the air intake of an internal combustion engine

An air filter, particularly for the intake air of an internal-combustion engine, including a housing 13, an air filter insert 16 arranged in the housing, and a cover 10 closing off the housing 13. The air filter insert 16 is essentially a rectangular cartridge which has a surrounding seal 18. This seal 18 is clamped in between the housing 13 and the cover 10 in such a manner that it separates the unfiltered-air space from the filtered-air space. In addition, clamps 19 are provided which fasten the cover and the housing to each other and the filter cartridge is simultaneously secured in the housing. Direct supporting contact between the cover 10 and the housing 13 occurs only adjacent the clamps 19, and simultaneously the seal has a very low Shore hardness. As a result, the cover no longer rests as previously on the housing over the whole length of the seal, but only in the area of the clamps.

A filter for cleaning lubricating oil of an internal combustion engine has a filter housing with an access opening on an upper side to insert and remove filter elements. A cover is arranged to close the access opening. The housing has an inlet opening for dirty fluid and an outlet opening for clean fluid. Furthermore, a drain opening is provided in the housing which can be opened and closed with a closure element. The closure element is operationally coupled to the cover such that when the cover is closed, the closure element closes the drain opening, and when the cover is opened, the closure element opens the drain opening, allowing the fluid to drain out of the housing.

Oil filter housing including a valved drain opening

An intake system for an internal combustion engine includes first and second inlet passages for each cylinder of the internal combustion engine. The second inlet passage is provided with a butterfly valve arrangement integrated into the flange area of the intake manifold for selectively closing or opening the passage, and a drive unit is provided for operating this valve arrangement depending on the operational state of the internal combustion engine.

A fluid filter, particularly for cleaning lubricating oil for internal-combustion engines of motor vehicles, which includes a filter housing 10 with a screw cap 11 and an annular filter element 12 inserted into the filter housing 10. The filter element 12 is pushed onto a supporting tube 15, which in turn is locked to the cap 11 or the bottom of the filter housing 10. Arranged on the cap or on the bottom are detent tongues 18 which engage with detent tongues 20 of the supporting tube 1B. Guiding surfaces 21 are provided for the detent tongues of at least one element.

A filter insert and a method for producing the same in which the filter insert has an accordion-folded filter medium. In a first operating step, folded edges are impressed on the filter medium. Subsequently, by glue application devices which are provided with glue application nozzles, at least two glue beads are applied to the surface of the filter medium and the folding is carried out subsequently. At least one of the glue application devices is movable transversely to the transport direction of the filter medium.

Intake manifold and process for making it

An air filter, particularly for ventilating the interior of motor vehicles, is provided. The air filter includes a housing having an unfiltered-air inlet and a clean-air outlet, as well as a filter medium folded in an accordion-like shape. The filter medium is arranged in a filter insert which has a surrounding seal. An adapter is integrated in the housing and also includes a surrounding sealing device to provide an effective seal between the unfiltered-air and clean-air sides of the housing. The filter insert is arranged in the adapter and is fixed in position via a cover flap of the housing.
