Abstract
An oil seal is formed between two casing parts which have oil passages which are joined by a hollow dowel. A sealing ring surrounds the dowel and is compressed between the casing parts. In order to allow relatively loose fitting dowels and appreciable tolerances in the spacing between the passages and the gap between casing parts, the sealing ring has the form of two annular webs which are pressed together as the casing parts are clamped together. Moreover, one web has a frustoconical surface which engages a frustoconical countersunk surface in one of the casing parts. In a modified embodiment, the oil pressure is communicated to the space below the webs and spreads these into pressure contact with the casing parts.
