The invention relates to a device for injecting a fluid, in particular a cryogenic fluid, the device comprising a fluid feed head and a fluid dispenser body, detachably mounted on said feed head, said feed head comprising a groove for circulating the fluid fed to said body, said groove being closed when the body is mounted on the feed head and said groove being open when the feed head and the body are detached from one another.

Device for injecting a cryogenic fluid through the base of a mixer

The invention relates to equipment for producing cool packs containing an amount of carbon-dioxide snow, which includes: a set of at least two cells, each of which is capable of receiving and supporting a shell to be filled; a feeding tube connected, at the upstream portion thereof, to a liquid CO2 source; a set of at least two injection manifolds, each injection manifold being located opposite a cell in which a casing to be filled is to be positioned, and each manifold being connected, at the upstream portion thereof, to the feeding tube, wherein each manifold comprises an injection port at at least one location along the length thereof, the equipment being characterized in that: i) the end of each manifold opposite the feeding tube is formed as a sealed end provided in the form of a substantially rounded tip; j) each injection port located on a manifold is a provided as a threaded opening having a given diameter D and is capable of receiving an injection nozzle by means of screwing; k) said equipment comprises at least two injection nozzles, each injection nozzle being provided in the form of a part that is cylindrical over at least a portion of the length thereof, said cylinder being a hollow cylinder, the threaded outer diameter of which is equal to the diameter D of at least one of the threaded openings of at least one of the manifolds, and the inner diameter d of which is less than D.

Equipment for producing cooling packs consisting of a shell made of a porous material containing an amount of carbon-dioxide snow enclosed and retained inside the casing

The injection device according to the invention, intended to be attached to the wall of the bottom of a container containing a product to be cooled in bulk, includes a hollow cylindrical body in which a valve forced by a spring is inserted, a throughchannel appreciably parallel to said valve intended to be fed by pressurized cryogenic fluid, one end of said through-channel being connected to the cryogenic fluid feed system and the opposite end opening into the seat of the valve.
