Abstract:
A device (1) for receiving an ingredient cartridge (2) and extracting the ingredient by passing heated liquid through the cartridge, has a cartridge seat (10) and a liquid injection arrangement (50, 60, 61, 70, 80, 81) for injecting heated liquid into the cartridge seat. The cartridge seat comprises a first cartridge support (20) and a second cartridge support (30) facing the first support. The first and second cartridge supports are arranged to be movable relative to one another from an open position for insertion or removal of a cartridge into the seat to a closed position for passing heated liquid through such a cartridge. At least one support (20) of the cartridge supports (20, 30) is hydraulically actuatable and movable into the closed position by the liquid injection arrangement. The liquid injection arrangement is configured to: pressurize and circulate unheated liquid to the at least one support (20) for actuating and moving said at least one support (20) by the circulating unheated pressurized liquid; and guide this circulating unheated pressurized liquid under pressure from the at least one support (20) via a heater (70) into the cartridge seat (10) for extracting the ingredient contained in the cartridge (2).
