Wasserabstossende Filterabdichtung

摘要

A filter seal (5) which is capable of passing oil and of removing contaminations from said oil comprises a layer of filter material (10) which is oil-permeable. Moreover, the filter material (10) is water repellent, such that water droplets are rejected. In order to also reject the smaller water particles e.g. water molecules, furthermore hydrophilic means are provided for absorbing small water particles.
