Abstract
Abstract An air bubble separating device includes a reservoir provided with an inlet and an outlet. A control plate is provided in the reservoir in such a position relative to the inlet as to generate a vortex flow of the liquid delivered from the inlet. A stability plate, mounted above the inlet for stabilizing the vortex flow, has a hole at the central portion thereof for passing therethrough air bubbles mixed in the liquid. A restricting member is mounted below the inlet for permitting the passage of the liquid to the outlet while restricting the passage of air bubbles therethrough.
