A cooler for an internal combustion engine may include a cooler block including a gas path for communicating a gas flow along a gas flow direction and a coolant path for communicating a coolant flow. The gas path and the coolant path may be thermally coupled to each other and may be fluidly separated from each other. The cooler may include a liquid separator for separating a liquid from the gas flow. The liquid separator may be arranged on the cooler block at an outlet side of the gas path. The liquid separator may include a reservoir for the separated liquid and an evaporator for evaporating the separated liquid.

A pressure control valve including a valve housing having a first opening and second opening. The valve housing including a valve member configured to control gas flow between the first opening and the second opening. The valve member is supported by a first membrane and a second membrane, both of which are formed on a single-piece membrane body.

Pressure control valve

The present invention relates to a fluid flow measuring device. The device includes a fluid flow having at least one of a volume flow rate and a mass flow rate. At least one spring element is included, which is exposed to the fluid flow, such that the spring element is elastically displaceable in at least one of a ferromagnetic and an electrically conductive mobile region depending on the dynamic pressure acting thereon with an eddy current sensor arranged stationarily. The eddy current sensor generates a measurement signal that is correlated with a distance between the eddy current sensor and the mobile region. The distance varies with the dynamic pressure-related displacement of the mobile region, and at least one temperature sensor is included, the temperature sensor measures an actual temperature of the fluid flow.

Fluid flow measuring device, valve device and measuring method

A positive crankcase ventilation oil mist separator system has a first separator unit, wherein the first separator unit includes at least one filter body arranged in a blow-by gas path such that blow by gas flows through the filter body; a second separator unit, wherein the second separator is an impactor separator arranged in a bypass path that bypasses the first separator unit; and a bypass valve, which opens the bypass path as soon as a differential pressure at the first separator unit exceeds a predefined value, wherein the second separator unit comprises an impact wall formed by a section of the filter body of the first separator unit, and a flow directing element which directs the blow-by gas flow against the impact wall when the blow-by gas path is open.

Oil mist separator

The invention relates to an internal combustion engine (), in particular in a motor vehicle, having a fresh air system () for supplying fresh air, which is extracted from the environment () of the internal combustion engine (), to combustion chambers () of the internal combustion engine (), and having a degassing system () for discharging blowby gas from a crankcase () of the internal combustion engine () and for supplying the blowby gas to the fresh air of the fresh air system (). Furthermore, the degassing system () has an oil separator () for removing oil from the blowby gas. In order to improve the performance of the oil separator (), a vacuum opening valve () is connected to the crankcase (). Said vacuum opening valve () opens as a function of a vacuum prevailing in the crankcase (), and then permits an inflow of fresh air into the crankcase ().

Internal combustion engine

A centrifugal oil mist separator device integrated into an axially hollow camshaft of an internal combustion engine should permit a good separation effect. To this end, a device is provided whereby
