Abstract: A valve assembly is disclosed, which includes a valve body defining a valve chamber and a moveable member. The moveable member has a valve element at its first end and an armature at its second end. The moveable member is moveable in an axial direction to selectively open and close the valve. The entire moveable member is spaced from the walls of the valve body when the valve is open or partially open. A flexible membrane forms a seal against the moveable member and the valve body to divide the valve chamber into a flow chamber in which the valve seat and valve element are located and a pressure compensation chamber within which the armature is entirely enclosed. A first fluid port is fluidly connected to the pressure compensation chamber via one or more bores in a pressure compensation flow path with at least one opening extending into the pressure compensation chamber at an axial position between the armature and the flexible membrane.

Abstract: When in use, the sealed cartridge (1) containing a certain amount of a substance intended for the preparation of a bewerage by dissolution or extraction with a liquid, is placed inside a liquid collector member comprised of a frusto-conical beaker (9). The assembly thus formed is placed inside a housing (21) of a "spoon" of a coffee machine. The top of the cartridge (1) is perforated by a perforator and injector member which injects a liquid under pressure inside the cartridge (1). The lower membrane (2) of the cartridge undergoes a deformation under the effect of the pressure thus generated and is pressed against perforator tips (13) at the bottom of the beaker (9). The liquid flows into the housing (21) and can be collected in cups. The invention makes it possible to optimize the contact time of the substance contained inside the cartridge with the liquid supplied for its dissolution or its extraction.
