Abstract (en)
[origin: EP0552841A2] Method and device for detecting undissolved gas in a hydraulic control system of the type containing a hydraulic-medium-pressure pump and a feed reservoir, based upon checking the compressibility of the medium and deducting the amount of undissolved gas from the thus obtained information by taking into account that an increase of the amount of undissolved gas in the medium results in a decrease of the compressibility of this medium. <IMAGE>
