Device for sterilizing a chamber

A device for cleaning and sterilizing the inside of a chamber, including a supply of sterilizing liquid for said chamber and a device for inducing variations in the pressure, amplitude, frequency and the gradient of said variations in the sterilizing liquid, whereby said device is adapted in such a way that cavitation occurs inside the liquid, the device inducing said pressure variations include a liquid column between the chamber and a switching organ, whereby the chamber can be cyclically connected to a depression, whereby the value thereof is related to the amplitude or respectively to the atmospheric pressure.
