TLDR
A pump assembly provides direct replacement of volumes of liquid from a reservoir with equal volumes of air preferably at substantially atmospheric pressure, the same pressure or with pressure equalization to be at least equal to atmospheric pressure as discussed by the authors.Abstract:
A pump assembly provides for direct replacement of volumes of liquid from a reservoir with equal volumes of air preferably at substantially atmospheric pressure, the same pressure or with pressure equalization to be at least equal to atmospheric pressure. A slide arrangement preferably positively displaces liquid from the reservoir and air into the reservoir. The pump draws air from the atmosphere into a chamber from which the air either is available for passage to replace liquid from the reservoir or is pressurized to assist dispensing liquid, preferably, admixing with the liquid to provide foaming. Gravity separation of air and liquid to be dispensed is used to replace liquid with air in the reservoir and to selectively place air and liquid into communication with passageways for ejection.read more

Foam-dispensing pump container
Shoji Uehira,Takashi Miyagi +1 more
TL;DR: In this paper, the valve seat portion of a foam-dispensing pump was shown to protrude inwardly below the air-liquid mixing unit and formed of the flexible member that can come into contact with the outer peripheral face of the latch portion of the rod-shaped valve body, thereby reducing a backflow of the foam or liquid into the air passage.
