Abstract:
A beverage machine (300) comprises a pump (106) for pumping water (104) from a water tank (102) through a heater (108) and a hollow injection needle (200) into a beverage capsule (202), a pressurization device (302) comprising a cavity (304), a water line (116) connecting an outlet of the pump (106) to said cavity (304), a pressurization device valve (316) between the pump (106) and said pressurization device (302), a gas line (312) connecting the pressurization device (302) to said hollow injection needle (200), and a discharge valve (314), such that the pressurization device (302) receives a volume of water (104) from the pump (106) to compress a volume of gas (310) held in the cavity (304) of said pressurization device (302), and such that said compressed volume of gas (310) is discharged through the hollow injection needle (200) when the discharge valve (314) is opened.
