Japanese Patent JPH0335551
Kind Code:
B2
Abstract:
An oil seal is formed between casing parts (10 and 11) where oil passages (12 and 13) are joined by a hollow dowel (15) utilising a sealing ring (16) surrounding the dowel and compressed between the casing parts. In order to allow relatively loose fitting dowels and appreciable tolerances in the spacing A between passages and the gap T between casing parts, the sealing ring (16) has the form of two annular webs (19 and 20) which are pressed together as the casing parts are clamped up together. Moreover, one web has a frustoconical surface (17) mating in a frustoconical countersunk surface (22) in the casing part (11). In a modified embodiment the oil pressure is communicated to the space between the webs (19 and 20) and spreads these into pressure contact with the casing parts.
