A liquid direct injection assembly includes a direct injection supply kit to mix liquid components into a mixture and deliver the mixture to a treatment device. The supply kit includes one or more liquid component containers that each include an elongated flexible bladder and a discharge nozzle to discharge a corresponding liquid component from the bladder. The supply kit also includes one or more metering bodies each defining a metering orifice to control a flow rate of the corresponding liquid component from the bladder. The liquid direct injection assembly also includes a container tray configured to removably support a liquid component container.

Device and method for filling pressurized gas tanks, particularly vehicle pressurized hydrogen tanks, the device comprising a liquefied gas source, a transfer circuit comprising two parallel transfer lines each having an upstream end linked to the liquefied gas source, at least two separate downstream ends intended to be each removably connected to a tank to be filled, each of the two transfer lines comprising: a pump, a vaporizer for evaporating the pumped fluid, a branch for bypassing the vaporizer and a distribution valve(s) set configured to control the flow of fluid pumped and distributed between the vaporizer and the branch line, the device further comprising a storage buffer(s), which storage buffer(s) is(are) connected in parallel to each of the two transfer lines via a set of valves.

A liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are contained in the chamber. The first conduit connects the chamber to an outlet port in the container where the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an existing flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.

A liquid dispensing system for dispensing two or more liquids of different composition, viscosity, solubility and/or miscibility at high filling speeds into a container through a unitary dispensing nozzle to improve homogeneous mixing of such liquids, while said nozzle is an integral piece free of any movable parts.

A preparation and dispensing system prepares and dispenses a personalized composition from N reserves (501-502) of active compounds (A1-A2), N being an integer greater than or equal to 1, which is accurate, quick, easy to implement, hygienic and economical. The system comprises a pneumatic-pressure generator (200) connected to a pressure distributor (300) comprising N pressure changeover switches (301-306), each one having at least one inlet (I1) connected to the pressure generator, one inlet (I2) connected to atmospheric pressure and an outlet (311-316) connected to an inlet of a reserve of active compound.
