Abstract: An air pressurized liquid decanter is disclosed, which is generally comprised of a pump unit, an external handle, an insulated container body which includes an interior vessel and a base unit. The pump unit is contained within a pump housing which has radially disposed apertures. A cam shaft residing within the pump housing extends through the horizontally disposed apertures and is affixed in rotatable engagement to the external handle. The cam shaft is maintained in mechanical communication with a vertically-movable check valve residing within the pump housing. The vertically-movable check valve is, in turn, placed in mechanical communication with a support disk residing within the pump housing. The support disk overlays a flexible bellows unit, which has an open upper end in atmospheric communication with the vertically-movable check valve and pump housing. The flexible bellows unit also has an open lower end in atmospheric communication with a bulkhead, and with the insulated container body.
