Examples disclosed herein relate to a dispensing device including a syrup unit which transmits via one or more orifices one or more syrups and water to a dispensing block, a syrup source coupled to the syrup unit which provides the one or more syrups to the syrup unit, a water source which provides water to the syrup unit, and a cf valve coupled to a first orifice upstream of a solenoid valve where the cf valve provides a first range of pressures to the solenoid valve and where the first orifice is coupled to the dispensing block.

A device for mixing and metering of at least two gases, comprising two bodies that can be displaced relative to each other, wherein margins of the bodies are in contact with one another and between these margins at least two rectangular openings for one gas each can be formed, wherein a displacement of the bodies relative to each other automatically causes an increase of one opening and a decrease of the other opening, wherein the resulting total cross-section of the openings remains constantly the same here. Moreover, the device comprises a control element which is arranged adjacent to the two bodies and in contact therewith, wherein the control element can be translationally displaced in a continuous manner between a closed position and an open position in order to close or to open the openings.

A device for pastillating a flowable product, in particular a melt. The device has a revolving belt and a drop former, and the drop former deposits product drops on an upper run of the belt. The product drops, in the course of transportation on the upper run of the belt, solidify to form pastilles, and an arrangement for wetting the belt with a liquid release agent is provided upstream of that region in which the product drops are deposited on the belt. The release agent prevents or reduces the adhesion of the product drops to the belt, and a proportional metering pump is provided for continuously mixing the release agent from at least two liquid components during the operation of the device.

A valve assembly and fluid arrangement for continuous delivery of volumetrically proportioned gases or like fluids includes a valve assembly and a volumetric fluid storage bank, which has first and second sets of fluid storage chambers. The valve assembly alternately supplies a consumer with a blend of gases from the first set of fluid storage chambers while charging the second set of fluid storage chambers from pressurized gas sources, and, upon a threshold depletion of gases from the first set of chambers, supply the consumer with a blend of gases from the second set of fluid storage chambers while charging the first set of fluid storage chambers from the gas sources. Upon the threshold depletion of gases from the second set of chambers, the valve assembly again supplies mixed gases from the first set of chambers while charging the second set of chambers, and the process repeats.

Systems, apparatus and methods are described herein for dispensing a carbonated beverage. In some embodiments, an apparatus includes a first cylinder that defines an interior region that can contain a volume of carbonated water and a first piston separating the interior region. A second cylinder is coupled to the first cylinder and defines an interior region and a second piston separating the interior region and operatively coupled to the first piston. The interior region of the second cylinder can contain a volume of beverage concentrate. A flywheel assembly is operatively coupled to the first cylinder and to the first piston and can control a predetermined ratio of a volume of carbonated water from the first cylinder and a volume of beverage concentrate from the second cylinder to be dispensed when a force is exerted on the piston by a flow of carbonated water through the first cylinder.
