An annular filter element and sealing element for an oil separator of a crankcase ventilation system, the filter element has a covering surface extending parallel to a direction of flow, together with at least one cover element covering surface in at least some regions. An oil separator is taught having the filter element with at least one pressure control valve controlling crankcase pressure and has a valve closing body that operates in conjunction with a valve seat. The sealing element having at least one radially sealing region that is configured to act in the direction of the radius of the annular filter element, and at least one axially sealing region that is configured to act in the direction of the longitudinal axis of the annular filter element.

Sealing element, annular filter element, oil separator, and method for controlling prevailing pressure in crankcase ventilation system

A sealing element () for an annular filter element () of an oil separator () of a crankcase ventilation system, wherein the annular filter element () is configured to separate oil from fluid. The sealing element () fulfills more than one sealing function and yet is easy to use and replace. The sealing element () having at least one radially sealing region () that is configured to act in the direction of the radius () of the annular filter element (), and at least one axially sealing region () that is configured to act in the direction of the longitudinal axis () of the annular filter element ().

Sealing element, annular filter element, oil separator, and method for opening filter housing of oil separator

The invention describes a filter element for an oil separator of a crankcase ventilation system in which a filter element is configured to separate oil from fluid and that has a covering surface extending parallel to a direction of flow, together with at least one cover element covering surface in at least some regions. An oil separator is taught having the filter element with at least one pressure control valve controlling crankcase pressure and has a valve closing body that operates in conjunction with a valve seat.

Filter element, oil separator, and method for controlling prevailing pressure in crankcase ventilation system

A ring filter element has a filter medium body flowed through radially form an interior of the filter medium body to an exterior of the filter medium body. A bypass valve is provided that is adjustable between a blocking position, separating a raw side at the interior of the filter medium body from a clean side at the exterior of the filter medium body, and an open position, connecting the raw side of the filter medium body with the clean side of the filter medium body. The bypass valve is arranged in an axial direction of the filter medium body at least partially external to a first axial end face of the filter medium body and extends radially at most up to the clean side of the filter medium body. The ring filter element is employed in a filter device of a crankcase.

Ring filter element, in particular for oil separation of a crankcase, and filter device

Crankcase ventilation device housing

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.

Separating module, line module, and ventilation device

A separating device (), in particular for a crankcase venting device of an internal combustion engine, includes an inlet () supplying a fluid containing particles to be separated, a baffle plate () separating the particles from the fluid, several nozzles () oriented toward the baffle plate (), and a pivotable flap () that, as a function of its pivot position, fluidically connects a first number of nozzles () with the inlet () and fluidically separates from the inlet () a second number of nozzles ().
