Abstract
In order to eliminate bubbles in a liquid, the liquid is introduced into a flow passage having circular cross section as tangential flow which turns into swirl flow circulating around axis along the shape of the flow passage and that accelerates and decreases the pressure of the swirl axis and collects bubbles at the portion where pressure becomes lowest, and discharges the collected bubbles through a vent hole or a small vent pipe.
