Microgravity dispenser with agitator, metering device and cup filler

A metering device for a microgravity dispenser system comprising:

• a main piston cylinder housing;
• a main piston cylinder provided within said main piston cylinder housing;
• at least two channels axially formed within said main piston cylinder housing, said main cylinder being reciprocally engagable with said at least two channels to force predetermined quantities of sYrup therethrough;
• carbonated water inlet means, formed in a first end of said cylinder housing, for forcing carbonated water into said main cylinder housing;
• carbonated water outlet means, formed adjacent said carbonated water inlet means, for expelling carbonated water to the exterior of said main piston cylinder housing;
• means for circulating syrup from at least two syrup supply tanks to corresponding ones of said at least two channels, whereby a predetermined quantity of a selected syrup is metered with a predetermined quantity of carbonated water within said dispenser system;
• means, formed in a second end of said main cylinder housing, for applying an axial pressure to an upper surface of said main piston cylinder, said axial pressure acting to keep carbon dioxide dissolved in said carbonated water in solution during discharge of said carbonated water to the exterior of said main piston cylinder housing;
• and
• means for releasing said axial pressure from the upper surface of said main piston cylinder, whereby said release of pressure enables syrup and carbonated water to enter said main piston cylinder housing.
