<p>PCT No. PCT/EP89/00830 Sec. 371 Date Jan. 11, 1991 Sec. 102(e) Date Jan. 11, 1991 PCT Filed Jul. 15, 1989 PCT Pub. No. WO90/01130 PCT Pub. Date Feb. 8, 1990.The pressure compensator (2) is provided with gas-pervious but water and lubricating oil retaining diaphragms (10) which are supported on supporting grids (13) of less elastic material and elastomer rings (12). The diaphragms (10) permit the utilization of their flexibility for periodic ejection of dirt coatings automatic with the aid of pressure oscillations resulting during operation which lead to alternating bulgings and dropping of dirt. The installation of the diaphragms (10), while keeping an interspace (14) that remains at least on one side free, is provided in an insert body (3) which, depending on what may be needed, can be designed as a nipple, an annular cassette or directly as a seal element.</p> |
