A device for selectively dispensing and mixing a plurality of beverages, having separately for each beverage a storage unit a pump unit and a dispensing unit, the units for each beverage are connected in series by pipe conduits, the dispensing units being combined to a bundle to dispense and mix the beverages in selected quantities and combinations in a receptacle, such as a drinking-glass, in order to prevent admittance of air both into the storage units and the dispensing units, and to prevent after-dripping and incorrect dispensing. Each storage unit comprises an intermediate storage unit provided between a storage container and a respective pump unit and arranged to receive a volume of beverage larger than the volume dispensable on each operation by the pump unit via the dispensing unit. Each dispensing unit comprises a dispensing nozzle of resilient material and actuable by the pressure from the pump unit only.
A device for selectively dispensing and mixing a plurality of beverages, having separately for each beverage a storage unit, a pump unit and a dispensing unit, said units for each beverage being connected in series by pipe conduits, each storage unit comprising an intermediate storage unit provided between a storage container and a respective pump unit and arranged to receive a volume of beverage larger than the volume dispensable on each operation by the pump unit via said dispensing unit, and said dispensing units being combined so as to provide a bundle to dispense and mix the beverages in selected quantities and combinations into a receptacle, wherein each intermediate storage unit comprises at least one inlet housing for communication with a respective storage container, and a storage vessel for communication with said inlet housing and with the respective pump unit and means for venting said inlet housing and said storage vessel to ambient gas, and wherein each dispensing unit comprises a dispensing nozzle of resilient material and actuable by the pressure from said pump unit only.
A device for selectively dispensing and mixing a plurality of beverages, having separately for each beverage a storage unit, a pump unit and a dispensing unit, said units for each beverage being connected in series by pipe conduits, the dispensing units being combined so as to provide a bundle to dispense and mix the beverages in selected quantities and combinations into a receptacle, wherein each storage unit comprises an intermediate storage unit provided between a storage container and a respective pump unit and arranged to receive a volume of beverage larger than the volume dispensable on each operation by the pump unit via said dispensing unit, wherein each dispensing unit comprises a dispensing nozzle of resilient material and openable by the pressure from said pump unit only;
A device for selectively dispensing and mixing a plurality of beverages, having separately for each beverage a storage unit, a pump unit and a dispensing unit, said units for each beverage being connected in series by pipe conduits, each storage unit comprising an intermediate storage unit provided between a storage container and a respective pump unit and arranged to receive a volume of beverage larger than the volume dispensable on each operation by the pump unit via said dispensing unit, and said dispensing units being combined so as to provide a bundle to dispense and mix the beverages in selected quantities and combinations into a receptacle, wherein each pump unit comprises a pump valve assembly of plug-in type including a housing having a cylindrical bore, whereby an inlet port, a pumping port and an outlet port extend into the cylindrical bore, and including a valve body insertable into said bore, said valve body having a first check valve arranged between the pump port and the inlet port and having a second check valve arranged between the outlet port and inlet port.
