Abstract (en)

The present invention provides a stable working fluid for use in a viscous coupling which is insusceptible to viscosity decreases due to thermal decomposition as well as viscosity increases or gelation, which comprises a specific polyorganosiloxane as a base oil having one or more selected from the group consisting of sulfonate, phenate and salicylate incorporated therein, and which may further comprises sulfur, phosphorus and chlorine compounds incorporated therein.
