A liquid mist separation device for separating liquid from a gas flow may include a nozzle plate including at least one nozzle which is open at least in part and at least one baffle plate. The device may also include at least one valve element which, together with the nozzle plate, forms at least one variable nozzle. The at least one variable nozzle may be arranged fluidically parallel to the at least one nozzle. The nozzle plate and the at least one valve element may be arranged axially displaceable relative to each other. The nozzle plate and the at least one baffle plate may be disposed at a fixed distance with respect to one another. Opposite the at least one nozzle and the at least one variable nozzle a baffle plate may be arranged, which deflects the gas flow emerging from the respective nozzle and on which liquid droplets precipitate.

A pump device may include a side channel compressor that may include a housing having a conveying chamber and a fluid inlet and outlet. The compressor may include an impeller having blades radially on an outside and which may be mounted rotatably in the housing, the blades lying in the conveying chamber, and a shaft mounted rotatably about an axis of rotation and on which the impeller may be fastened. The conveying chamber may have at least one side channel running in a region of the blades and connecting the fluid inlet and outlet to one another in a circumferential direction. An intermediate region may be formed in the circumferential direction between the fluid inlet and outlet and in which a distance of the blades in an axial direction to the nearest wall may be such that no more than a predetermined amount of fluid flows in the intermediate region.

Pump device for driving blow-by-gas

A vehicle may include an internal combustion engine having a crankcase and a supercharging apparatus, and a crankcase ventilation apparatus having at least one oil-separating apparatus including at least one oil separator. An oil return line may communicate separated oil from the crankcase ventilation apparatus to the crankcase. An ejector pump may be driven via a compressed air flow of the supercharging apparatus and may be configured to generate an underpressure for driving a blow-by gas. The crankcase ventilation apparatus may include a pump control valve configured to at least one of regulate and control the compressed air flow through the ejector pump.

Crankcase ventilation apparatus

A cylinder head cover for a cylinder head of a piston engine may include a cover body for mounting on the cylinder head. The cover body may include a cover body section and a first longitudinal side edge disposed opposite a second longitudinal side edge. An outer cover seal may seal off the cover body from the cylinder head and extend completely around along an outer edge of the cover body. A securing bridge may be fitted over the cover body on an outer side along the cover body section from the first longitudinal side edge of the cover body to the second longitudinal side edge.

Cylinder head cover

An oil mist separator for a crankcase ventilation system of an internal combustion engine may include a nozzle device having a plurality of nozzles. The plurality of nozzles may each have a nozzle outlet. An impact wall may be disposed opposite to the plurality of nozzles and may be covered with a separation material. A distance may be configured between the plurality of nozzles and the separation material, which is reduced compared to a surrounding region. The plurality of nozzles may project towards the separation material and thereby reduce the distance of the nozzle outlet of the plurality of nozzles to the separation material compared to the surrounding region.

Oil mist separator

A separation device for separating contaminates from a gas flow may include a raw chamber receiving a contaminated gas and a clean chamber out of which a treated gas exits. A dividing wall may separate the raw chamber from the clean chamber. The dividing wall may include a perforated region defining a plurality of passage openings. The gas flow may be communicated from the raw chamber to the clean chamber via the plurality of passage openings. A gas-permeable separation structure may be arranged on a wall outlet side of the dividing wall facing the clean chamber. The separation structure may separate contaminates from the gas flow when subjected to a through flow.

Separation device for an aerosol stream

A vehicle may include an internal combustion engine having a crankcase and a crankcase ventilation device. The crankcase ventilation device may have at least one oil separating device and an oil return that feeds separated oil back to the crankcase. The vehicle may include a conveying device for driving a fluid other than blow-by gas. The conveying device may also drive the blow-by gas in the crankcase ventilation device.

Crankcase ventilation device

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.

An oil mist separator for a crankcase ventilation system in an internal combustion engine is disclosed. The oil mist separator is an impact type separator that includes a nozzle device having at least one nozzle, an impact wall and a separation material configured therebetween. The impact wall is located opposite to the at least one nozzle and may be coated with the separation material. A distance is configured between the nozzle and the separation material, and is reduced compared to a surrounding region, and wherein the separation material in a region of the opposing nozzle projects towards the same and thereby reduces the distance of a nozzle outlet to the separation material in this region compared to the surrounding region.

A combustion engine, in particular that of a motor vehicle, includes a ventilation device for feeding gases of a crankcase of the combustion engine enclosing at least one crankshaft to an air feed of the combustion engine, wherein the air feed feeds an airflow rate to the combustion engine. An adapter device may fluidically connect a full load path of the ventilation device to a full load line of the ventilation device and a part load path of the ventilation device to a part load line of the ventilation device.

Internal combustion engine

The present invention relates to a device for venting a crank space in an internal combustion engine () having a suction device () for sucking out blow-by gases from the crank space () and having a venting line () which leads from the crank space () to the suction device () and in the course of which a throttle device () or a pressure regulating element () is arranged in order to bound a partial pressure which is generated by the suction device () in the crank space (). It is essential to the invention here that an oil mist separator () which is embodied as an impactor is integrated into the throttle device () or into the pressure regulating element ().
