Abstract: A method of making an air filter insert for cleaning the combustion air of an internal combustion engine. The method includes producing the filter insert (21) from a pleated filter medium (33) which is formed into a hollow cylinder, in which at least one end plate (33, 34) made of thermoplastic elastomer or thermoplastic polyurethane is disposed on the axial end faces of the filter medium (33). The at least one end plate (33, 34) is bonded to the cylindrical filter medium (33) by heating the filter medium or the end plate (33, 34) with a high-temperature heating element and fusing the filter medium (33) and the end plate (33, 34) to form a welded joint.

Abstract: A housing, in particular a pot-shaped filter housing. To connect housing pot 10 and cover 11, a joint consisting of closure elements such as locking clamps or bow clamps 16 is proposed which can be attached at the periphery of the housing via receivers 18. As there are more receivers 18 provided on the housing than locking clamps 16 which are required for absorbing retention forces, it is possible to vary the exact fitting position of the locking clamps according to the respective space available for receiving and mounting the housing. This is essential, because the rotating radius 27 of the tension levers 17 of the locking clamps has to be considered when mounting the locking clamps 16. It is thus possible to provide housings for any field of use with variable receivers for the closure elements.

Abstract: A mixing device is suggested for introducing a fluid into another flowing liquid, especially for use as an oil lubricator. This lubricator consists of an exterior venturi pipe 18 and an interior venturi pipe 16, whereby a feed line 13 ensures the supply of the oil to be mixed into the interior venturi pipe 16. The feed line 13 is connected to the storage tank 28 of the lubricator by means of a butterfly valve 30 and a uptake 29. A control insert 20 is mounted in the ring-shaped cross-section between the interior pipe 16 and the flow channel 18. This has elastic blades in particular, which largely close the circular ring section at lower amounts of throughput of the air, such that even in this operational state, consistently good mixing results of the oil with the air can be guaranteed in interior pipe 16.

Abstract: An air filter element, in particular for the cleaning of combustion air for internal combustion engines, in air filters with a substantially cylindrical, air-permeable housing. The air filter element has a raw air inlet area (2) and a clean air outlet area (3). The clean air outlet area is arranged substantially concentrically on one of the end surfaces of the cylindrical housing (1), and the raw air inlet area occurs substantially across the surface of the housing (1). An air-permeable center tube (4) connecting to the clean air outlet area extends inside the housing (1), and a substantially metal-free filter insert (5) is slid over the center tube (4) and separates the clean air from the raw air side. The opposite end surface (7) of the insert is sealed, and the clean air outlet side of the housing (1) has an axial seal (8) on the face thereof, it being possible to divide the housing (1).
