Abstract
The device for regulating a flow rate of an air-liquid centrifuge separator includes a gas outlet pipe, an outlet pipe for separated liquids and an inlet pipe through which a fluid to be separated enters the separator. The device includes a by-pass pipe, arranged between the liquid outlet pipe and the fluid inlet pipe, which removes liquid from the liquid outlet pipe and transfers it to the fluid inlet pipe when a pressure of the liquid in the liquid outlet pipe exceeds a predetermined level. The device is particularly useful in separators for dental aspiration plants.
