This invention relates to hydraulic fluids, and is mainly, but not exclusively, concerned with fluids used as a power transmission medium in hydraulic brake systems for engines, e.g. car engines and aircraft.

54 deler DMDGG [ester av diethylenglycolmonomethylether og glutarsyre] 30 deler triethylenglycoldipropionat Gummisvelningskarakteristikaene til blandingene i Eksempel 7 til 14 ble bestemt ved å dyppe en SBR (styren-butadiengummi) kopp i blandingene i tre dager ved 120°C, og måle forandringen i koppens diameter. Tidligere bestemmelser av gummisvelningsegenskapene ble bestemt ved hjelp av Archimed.es prinsipp, beskrevet i British Patent Specification No. 1„083.324 ved å dyppe prover av en syntetisk gummi (merket G9) og en naturlig gummi (merket R32) i blandingene. De opp--nådde resultater, og andre egenskaper, er sammenlignet i folgende tabell med de resultater som ble oppnådd og egenskapene til, de estere (ublandet) som dannet hovedinnholdet i blandingene» 54 parts DMDGG [ester of diethylene glycol monomethylether and glutaric acid] 30 parts triethylene glycol dipropionate The rubber swelling characteristics of the compositions of Examples 7 to 14 were determined by dipping an SBR (styrene-butadiene rubber) cup into the compositions for three days at 120°C, and measuring the change in cup diameter . Previous determinations of the rubber swelling properties were determined using Archimedes' principle, described in British Patent Specification No. 1„083,324 by dipping samples of a synthetic rubber (labeled G9) and a natural rubber (labeled R32) into the mixtures. The results achieved, and other properties, are compared in the following table with the results obtained and the properties of the esters (unmixed) which formed the main content of the mixtures"
Generelt kan man si, at de resultater man oppnådde av bestemmelse av gummisvelningskarakteristikaene, var minst like gode som, og i mange tilfeller vesentlig bedre enn de karakteristika som man kunne ha ventet fra en teoretisk beregning på basis av blan-dingenes enkelte konstituenters gummisvelningskarakteristika. In general, it can be said that the results obtained from determining the rubber swelling characteristics were at least as good as, and in many cases significantly better than, the characteristics that could have been expected from a theoretical calculation based on the rubber swelling characteristics of the individual constituents of the mixtures.
Væskene i henhold til foreliggende oppfinnelse, har ogs|i den fordel at de er meget lavhygroskopiske og meget lik de karakteristika som de væsker som er beskrevet i British Patent Specification No. 1.083.324. The liquids according to the present invention also have the advantage that they are very low hygroscopic and very similar to the characteristics of the liquids described in British Patent Specification No. 1,083,324.
