A throttle valve, particularly suited for hydraulic shock absorbers dashpots for motor vehicles, which automatically compensates for a change in the viscosity of the liquid flowing therethrough as a result of a liquid-temperature change. A temperature-responsive expansible ring preferably coacts with resilient valve plates to regulate the flow apertures, and may have either 1.degree. or 2.degree. of freedom of movement in expansion.
