ABSTRACT:
A method and apparatus for deaerating a liquid in a substantially closed liquid circulation system, wherein an amount of liquid is withdrawn from the circulation system and is introduced into a closed reservoir via a valve which is alternately open and closed, wherein by a pump which is operative in the open as well as the closed positions of the valve an underpressure can be created in the reservoir for the purpose of deaerating the liquid, and the liquid can be sucked from the reservoir and added to the circulation system again, separated air being discharged via a vent unit to the environment. For the valve adapted to be opened and closed alternately, preferably a throttling valve is used.
