Device for sterilizing a chamber

This cleaning device and stérilisationà inside an enclosure (1) comprises a power supply (2) of this chamber (1) in the sterilizing liquid, and means for indiuire, within this sterilizing liquid, of variations in pressure, amplitude, frequency and slope of said variations, adapted pourengendrer cavitation within the liquid. The means for inducing variations in pressure comprise a liquideentre column said chamber and a switching member (10) adapted to be connected cyclically, said enclosure (1) at a déression (7) which is theValue in relation to said amplitude respectively at atmospheric pressure.
