摘要： Une composition destinée à être utilisée dans un dispositif de transfert thermique du type à compression comprend, en tant que liquide de travail, de l'hydrofluoroalkane ou de l'hydrochlorofluoroalkane, et comme lubrifiant un produit de réaction ou un ester comprenant les résidus d'un alcool monofonctionnel et d'un alcool difonctionnel, et au moins un acide difonctionnel. Le lubrifiant est au moins partiellement soluble dans le liquide de travail et possède un bon indice de viscosité, de préférence supérieur à 130.

摘要： A lubricant composition for use in a sliding-vane rotary vane compressor has a polyalkyleneglycol base oil component and includes antiwear additives, antioxidants and metal passivators and, optionally, anticorrosion agents and vapour phase anticorrosion agents. The polyalkyleneglycol base oil component is a random copolymer of ethylene oxide (EO) and propylene oxide (PO) having an EO:PO ratio between 3:1 and 1:3, preferably between 1.5:1 and 1:1.5, and having been initiated with a compound having five carbon atoms or less.

摘要： This invention relates to lubricant compositions comprising a polyalkylene glycol and an ester wherein the polyalkylene glycol has the formula (I): RO-(CH2CH(CH3)O)n-CH3 where R is an alkyl group with 1 to 15 carbon atoms and n=1 to 35. The lubricant compositions of the invention do not readily form stable emulsions with water. This feature makes the lubricant compositions of the invention particularly suitable for use with air compressors where it is very difficult to exclude moisture.
