LIQUID DISPENSING UNIT AND SYSTEM

摘要

LIQUID DISPENSING UNIT AND SYSTEM There is disclosed a system and dispensing units for the controlled and metered dispensing of one or more liquid products. The basic system employs a pressure source for pressurization of the liquid product and the pressurized dispensing of the liquid product from the dispensing units. In addition to the basic illustrated system, there are disclosed novel dispensing units which enable the dispensing of a uniform or proportioned amount of liquid upon each instance of operation. Further, these units are constructed so as to permit the dispensing of several different liquids simultaneously from the same unit, or the selected dispensing of an individual liquid.
