Abstract
A separating module for a ventilation device has a housing that surrounds a separating element designed to separate liquid particles from a gas flow. A line module and a ventilation device with such a separating module and such a line module are provided. The housing of the separating module is designed to be connected to the line module that has at least three geometrically parallel channels and the housing of the separating module has corresponding housing openings to be connected to the at least three channels. Several separating modules and several line modules can be combined to adapt the ventilation system as needed.
Claims13
A separating module for a ventilation device, wherein
- the ventilation device is configured to discharge a gas flow laden with liquid particles from a component of an internal combustion engine, the separating module comprising:
- a separator housing which is substantially cylindrical and elongated along a central axis, the separator housing having
- an upper axial end face;
- a base axial end face;
- an annular outer wall that is substantially cylindrical and surrounds the central axis, and extends between the upper axial end and the base axial end;
- a separating element configured to separate liquid particles from the gas flow laden with liquid particles, the separating element arranged in an interior of the separator housing and comprising:
- an axially elongated annular filter medium arranged in the interior of the separator housing and surrounding the central axis;
- wherein the separator housing further includes:
- a housing bottom cover arranged on a base axial end face of the annular outer wall of the separator housing, the housing bottom cover having at least three flow openings configured to fluidically connect to respective flow openings provided in a connector flange of a line module, when the separating element is installed on the line module, the at least three flow openings including:
- an unfiltered gas opening, opening into the interior of the separator housing, the unfiltered gas opening configured to be supplied with gas flow laden with liquid particles;
- a liquid return opening, opening into the hollow interior of the separator housing, the liquid return opening returning liquid separated from unfiltered gas;
- a clean gas opening;
- a pressure control valve arranged on the separator housing and having a clean gas outlet channel connected to the clean gas opening provided in the housing bottom cover,
- wherein the pressure control valve is arranged on the separator housing on a radial outer side of the annular outer wall of the separator housing, the pressure control valve having a clean gas outlet channel formed at least partially by the housing bottom cover and arranged on the radial outer side of the annular outer wall of the separator housing, the clean gas outlet channel connected to the clean gas opening provided in the housing bottom cover.
