<p>PURPOSE:To prevent wear of a diaphragm in a conservator and thereby prevent the oil from permeative leakage by forming a lubrication coat on that side of diaphragm contacting the air by the use of mineral oil etc. CONSTITUTION:On a diaphragm 2 of a diaphragm type conservator 1, a lubrication coat 4 is formed on that side of diaphragm contacting the air using a lubricant composed of well lubricative mineral oil as main component and organic and inorganic compounds such as molybdenum disulfide, epoxy resin, polyethylene. polyamine, etc. By this simple means, the diaphragm 2 can be prevented from wear owing to repeated shift for a long time and, accordingly, permeative leakage of the oil can be prevented.</p> |
