Problems solved by technology

However, due to the underlying separation mechanism and design-dependent structure of this wire fabric or wire mesh, this filter device can only be used when the liquid droplets or solid particles are small (especially when the particle size is less than 1 μm). Achieving limited resolution

Embodiment Construction

[0036] FIG. 1 shows a schematic sectional view of a filter device 1 according to the prior art, which comprises a housing 3 and a filter insert 6 arranged in the housing 3 . The housing 3 of the filter device 1 has an inlet 4 for introducing the carrier gas 2 into the filter device 1 and an outlet 5 for leading the carrier gas 2 filtered through the filter insert 6 out of the filter device 1 . The flow of the carrier gas 2 through the filter insert 6 along the flow path 16 (from which liquid suspended particles such as oil are to be separated) is indicated by the dashed line. The carrier gas 2 flows from the inlet 4 along the flow direction 7 through the filter device 1 to the outlet 5 . Transversely to flow direction 7 , in this exemplary embodiment housing 3 has a substantially rectangular cross section, so that transversely to flow direction 7 a rectangular housing cross-section 10 with clear inner width results. The inlet 4 of the housing 3 has a likewise rectangular inle...

Abstract

An oil mist separator includes at least one filter device for separating off liquid suspended particles from a carrier gas. The filter device includes a housing having at least one inlet opening for introducing the carrier gas and at least one outlet opening for discharging the filtered carrier gas. Arranged in the housing is at least one filter insert through which the carrier gas can flow along a flow direction. There is also provided at least one guide device by which the flow path can be deflected. The at least one filter device can be arranged releasably in the oil mist separator, and a seal is provided preferably between a first fixing surface of the oil mist separator and a second fixing surface, to be fixed thereto, of the filter device.

Description

technical field [0001] The invention relates to an oil mist separator for separating oil contained in a carrier gas, in particular crankcase exhaust gas of an internal combustion engine, comprising a housing with at least one inlet for introducing the carrier gas and at least one outlet for the filtered carrier gas, wherein at least one filter element is arranged in the housing, through which the carrier gas can flow in the direction of flow. Background technique [0002] When an internal combustion engine is in operation, it is known that so-called blow-by gases (blow-by-gas: oil-containing gas) are produced, which are guided out of the crankcase of the internal combustion engine in order to avoid an increase in pressure in the crankcase and undesired discharge. blowby gas and the oil contained therein. In a closed crankcase ventilation system, the crankcase exhaust gas or carrier gas obtained from blow-by gases in the crankcase and including oil is led back to the intake ...
