    Abstract: The air intake ports of a liquid and air sucking and mixing gear pump are put into communication with the atmosphere through a collecting tank or chamber, in which the small amounts of foamy liquid-and-air emulsion flowing out from said ports during the stopping time of the pump are collected, and from which the amounts of emulsion are again sucked back into the pump as soon as the pump operation is again started.
