TETNINGSANORDNING FOR EN CENTRIFUGALGJUTNINGSMASKIN MED EN ROTERANDE FORM I EN VETSKEMANTEL INUTI ETT ICKE-ROTERANDE MASKINHUS

摘要

The sealing structure comprises an annular sealing member disposed in an annular recess in a ring fixed to the non-rotating casing of a centrifugal casting machine. The sealing member bears sealingly against an annular radial flange connected to rotate with the rotary mould of the machine. An elastically yieldable annular chamber is interposed between the inner end of the recess and the sealing member. A source of fluid under pressure is connected to the inside of the chamber to expand the latter and urge the sealing member against the flange.
