Apparatus for mixing and dispensing a beverage has a mixing head, a water line having a partially restricted outlet for backing up water pressure, a concentrate chamber having a diaphragm, a bypass line from the water line to the chamber for bypassing water from the water line against the diaphragm and forcing concentrate to the mixing head, and an open drain in the bypass line for exhausting water from the concentrate chamber; also disclosed is a method of mixing and dispensing a beverage in which pressurized water is first used to propel concentrate and then exhausted out a drain.

Method and apparatus for dispensing a beverage

A liquid dispensing pump is disclosed and is powerable by pressurized fluid intermittently applied to the pump, the pump has a pumping chamber, a pressurizing chamber, a movable member for transferring pressure to the pumping chamber, a fluid conduit to the pressurizing chamber for applying pressure to the pump, a valve in the conduit for preventing reverse flow of fluid and an open drain in fluid communication with the pressurizing chamber; any fluid used to power the pump is exhausted out of the drain both during and after pumping.
