A filter head may include a receiving component and a threaded metal nozzle insert at least partly injected into the receiving component. The receiving component and/or the filter head may be composed of plastic. The threaded metal nozzle insert may be structured as a cold extruded part. A plurality of radially extending ribs may be disposed in a cavity of the receiving component and/or the filter head. The ribs may be composed of plastic and/or integrally formed with the filter head. The ribs may extend along a radial direction from the threaded nozzle insert to a wall of the cavity. The ribs may additionally lead radially outward into an axial sealing surface of the filter head.

Filter head and threaded metal nozzle insert

A cylinder head cover having a bearing device that includes at least two bearing blocks for supporting a camshaft, and one connecting element. The bearing blocks are axially penetrated in a first through-opening by the camshaft and are fixed in an aligned position with respect to one another by the connecting element. The bearing blocks, the connecting element and the camshaft form a prefabricated assembly. The cylinder head cover is connected via at least one additional connecting element with the bearing device, whereby a unit consisting of the cylinder head cover and the bearing device are mounted on the cylinder head.

Cylinder head cover

The invention relates to a ventilation device () for an internal combustion engine () for evacuating blow-by gas from a crankcase (), comprising a first line (), which is connected at the one end to the crankcase () and at the other end, downstream of a forced induction device (), to a fresh-gas line () and contains a ventilation valve (), and a second line (), which is connected at the one end, upstream of the forced induction device (), to the fresh-gas line () and at the other end, between the crankcase () and the ventilation valve (), to the first line () and contains a throttle device ().

The present invention relates to a deaerating and aerating device () for an internal combustion engine () for discharging blowby gas out of a crankcase (), comprising a first line () which is connected at one end to the crankcase () and at the other end to a fresh gas line () downstream of a supercharging device () and which contains a deaerating valve (), and a second line () which is connected at one end to the fresh gas line () upstream of the supercharging device () and at the other end to the crankcase () and which contains a throttle device () and, parallel thereto, a non-return check valve () which provides a blocking action in the direction of the crankcase ().

Deaerating and aerating device for a supercharged internal combustion engine

The present invention relates to a cylinder head cover () for covering a cylinder crank case () of an internal combustion engine. It is essential to the invention here that at least one bearing upper part () for a camshaft () has at least one through-opening (), which is in alignment on the one hand with a screw-in/through-opening () in a bearing lower part () and/or with a screw-in opening () in the cylinder crank case () and on the other hand with a through-opening () in the cylinder head cover (), so that it is possible to fasten the cylinder head cover () and the bearing upper part () on the cylinder crank case () by means of a shared fastening screw (), in which the cylinder head cover () is produced from a material which has different material characteristics from the at least one bearing upper part ().

The invention relates to a device for separating a gas-liquid mixture, in which the liquid portion exists in the form of small particles, especially for ventilating a crankcase of an internal combustion engine, by separating and coagulating the liquid particles on a target area. The liquid mixture, after acceleration in acceleration openings provided for this purpose, impacts the target area at an approximately right angle. The aim of the invention is to improve the aforementioned device in such a manner that it allows as high a degree of separation as possible for different sized volume flows of mixtures. For this purpose, the number and/or the cross-sections of the acceleration openings is varied, depending on the volume flow of mixtures, between a small complete cross-section for a low volume flow and a large complete cross-section for a large volume flow.
