Liquid dispensing system

An improved concentrate/extract cartridge is provided for dispensing a liquid in an accurate and repeatable manner. The cartridge includes an electromagnetically actuated piston connected to a valve. The piston includes an exterior ring supported by a hollow interior web that is configured to permit a flow of fluid into the dispensing tube when the valve body is in contact with the valve seat. A membrane is located below the web and is in sealing contact with the internal ring when the piston is activated. This allows a precise and repeatable amount of the liquid to be dispensed with each stroke. Dispensers for dispensing the liquid from the cartridge for a number of applications are also provided. The dispensers each include an actuating coil into which the dispensing tube is inserted. A controller is connected to the coil for controlling the actuation of the piston/valve assembly for dispensing the fluid in the cartridge as required for the particular application.
