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.
