Abstract: Aerosol intended for dispensing several components for the production of a multi-component material comprising a dispensing assembly, a main container and one or more separate auxiliary containers for components to be dispensed, piston pumps, control part, piston chamber and non-return ball check valve.

Abstract: An apparatus including a mixing chamber for mixing together pressurized gaseous and liquid constituents, the mixing chamber including a lower region and an upper region; separate feed connections for the pressurized constituents of a mixture to be formed; a discharge connection for discharging a formed mixture to a chamber, wherein at least one of the separate feed connections includes passages in a wall of the mixing chamber; a spring located in the lower region of the mixing chamber biased against a pressure element located in the upper region of the mixing chamber, wherein the pressure element and an inner wall of the upper region of the mixing chamber define an annular space around the pressure element, wherein the passages comprise a porous part in the wall of the mixing chamber that open into the annular space around the pressure element in the upper region of the mixing chamber, and comprises an inlet for a pressurized gaseous constituent; and wherein the lower region of the mixing chamber comprises an

Abstract: A mixing chamber for mixing a gaseous component with a liquid component is disclosed. The mixing chamber is characterized by separate inlet connections for the respective components and an outlet for the mixture to a space at a lower pressure. The propellant inlet comprises a plurality of narrow channels positioned to create a turbulent flow in the mixing chamber to facilitate mixing of the components. Also disclosed is a method for forming narrow channels in a body or object by forming grooves in one of two interconnecting surfaces of the parts to thereby define the narrow channels when the parts are put together to form the body or object.
