摘要:
A device (1) has: a cartridge seat (10) arranged to receive an ingredient cartridge (2) for extraction; a beverage outlet (35) connected to this cartridge seat for dispensing beverage during extraction; and a liquid injection arrangement (50, 60, 61, 70, 80, 81) comprising a pump (60) for pressurizing and circulating liquid from a source (50) via the cartridge seat into the beverage outlet. The liquid injection arrangement further comprises a valve (80′) between the pump and the cartridge seat. The liquid injection arrangement is configured to release via the valve (80′) pressure from this pressurized liquid in the injection arrangement and maintain liquid in the injection arrangement from the pump (60) to the cartridge seat (10) after the pump is stopped, so as to inhibit dripping from the beverage outlet (35).
