Abstract: The invention relates to a device for filtering of oil circulating in an internal combustion engine, comprising an oil filter adapter for detachable fastening of an exchangeable oil filter to the engine block of the internal combustion engine. The invention is characterized in that the oil filter adapter has a receptacle with an inserted pin, the receptacle having an outflow for returning the oil flowing from the exchangeable oil filter, the receptacle having a channel which leads in particular to an oil pump, and the receptacle having a drain which leads in particular to the cylinder crankcase, the pin being inserted elastically pretensioned such that during operation the pin clears the outflow and closes the channel and the drain, and, when the exchangeable oil filter is loosened from the oil filter adapter, the pin is displaced by spring force and clears the outflow, the channel, and the drain. Furthermore the invention includes a pin which is designed for use in the device according to the invention.

Abstract: A module mountable in the crankcase of a vehicle for removing gases therefrom including a housing having an opening communicable with the crankcase, a set of bearings disposed in such housing, a hollow shaft journaled in such bearing having first and second partitions providing first and second axially disposed chambers, cooperating with said housing to provide first and second annular chamber, such shaft having a passageway intercommunicating the first axial chamber and the first annular chamber, a passageway intercommunicating the first axial chamber and the second annular chamber and a passageway intercommunicating the second axial chamber and the second annular chamber, a spiral, centrifugal separator mounted on such shaft in the first annular chamber, and a pillar mounted on the shaft in the second annular chamber and means connectable to motive means for rotating such shaft.

Abstract: The invention relates to an arrangement of a timing case cover on a reciprocating-piston internal combustion engine, having an engine block (ZKG), a crankshaft pivot-mounted in the engine block, an oil pan which tightly seals the engine block to the bottom, and a timing case cover which is located on the engine block on the front side, which adjoins the engine block via a second, end-side sealing surface, and which has a through opening to rout out the drive torque of the crankshaft for an accessory drive. To achieve reliable sealing and a short structure of the internal combustion engine, the sealing surface of the timing case cover or timing case covers, examined in a side view, is made to run obliquely down to the inside such that on the engine block-side a timing case chamber which decreases in its depth downward is formed.

Abstract: The invention relates to a device for guiding media in a cylinder block and crankcase of a reciprocating piston in-line combustion engine having a number of cylinders. To this end, the media guide comprises, among other things, at least one cross-channel that leads from one longitudinal side to the other longitudinal side of the cylinder block and crankcase. A structurally advantageous and simple design is provided by virtue of the fact that the cross-channel runs inside a free space, which is formed by recesses of two adjacent pistons in the lower area of the piston skirts and above the crankshaft bearing of the combustion engine.

Abstract: The invention relates to a device for filtering of oil circulating in an internal combustion engine, comprising an oil filter adapter 2 for detachable fastening of an exchangeable oil filter 3 to the engine block 1 of the internal combustion engine. The invention is characterized in that the oil filter adapter 2 has a receptacle 13 with an inserted pin 14, the receptacle 13 having an outflow 10 for returning the oil flowing from the exchangeable oil filter 3, the receptacle 13 having a channel 11 which leads in particular to an oil pump, and the receptacle 13 having a drain 12 which leads in particular to the cylinder crankcase, the pin 14 being inserted elastically pretensioned such that during operation the pin 14 clears the outflow 10 and closes the channel 11 and the drain 12, and, when the exchangeable oil filter 3 is loosened from the oil filter adapter 2, the pin 14 is displaced by spring force and clears the outflow 10, the channel 11, and the drain 12.

Abstract: The invention relates to a compensating shaft module of an internal combustion engine of a motor vehicle or similar, comprising a compensating shaft and a cartridge which receives the compensating shaft at least in areas and is maintained by means of bearings. Said cartridge comprises at least one raw blowby-gas-inlet which is connected to a centrifugal force separator of the compensating shaft and a conveyor which conveys the blowby-gases into the inside of the compensating shaft, whereby the rotor thereof is arranged on the compensating shaft which comprises at least one pure blowby gas outlet which is arranged downstream of the conveyor.
