Beschreibung
Zusammenfassung:	An exemplary foam-at-a-distance soap or sanitizer dispenser includes a housing, a container for holding a foamable liquid, and a pump in fluid communication with the container. The pump has a pump chamber air inlet, a pump chamber air inlet valve, a pump chamber air outlet, a pump chamber air outlet valve, a pump chamber liquid inlet, a liquid chamber liquid inlet valve, a pump chamber liquid outlet, and a pump chamber liquid outlet valve. The exemplary dispenser further includes an air conduit extending from the pump chamber air outlet to a remote mixing chamber and a liquid conduit extending from the pump chamber liquid outlet to the remote mixing chamber. The remote mixing chamber is located at a distance from the pump chamber air outlet valve and the pump chamber liquid outlet valve and that distance is greater than about 3 inches. A one-way liquid check valve is located proximate the mixing chamber, one or more mix media located downstream of the mixing chamber and an outlet nozzle located proximate the mixing chamber.
