PROCESS FOR DEGASSING A COUPLING LIQUID OF A PRESSURE WAVE GENERATOR APPARATUS EMPLOYING COUPLING LIQUID BY CHEMICAL ROUTE,COUPLING LIQUID THUS TREATED AND SHOCK WAVE GENERATOR USING SUCH A COUPLING LIQUID

摘要

The invention relates to a degassing method of a coupling liquid. & br / this process is characterized in that it comprises the addition to the coupling liquid at least one chemical fond of gas in an amount sufficient to absorb the said gas is substantially completely. This chemical substance is preferably an alkali metal sulfite or alkaline-earth metal -. & br / the invention makes it possible to obtain values of pressure of the pressure waves greater than those which are obtained by a conventional physical.
