Abstract: The invention relates to an appliance including an infusion chamber having an opening for receiving a fill, a closure part for said chamber, a water container connected to the chamber, pressurizing means for delivering air into the container, and control means suitable for causing a certain volume of water to be delivered from said container into said chamber, said pressurizing means being connected to a compression chamber that is arranged between said pressurizing means and said container and that includes inlet and outlet isolation means. According to the invention, with the water container full and the outlet isolation means including the control means, the control means is suitable for causing the compressed air to expand suddenly in the container and to flow with a curve of decreasing pressure. The invention is applicable to appliances for household use.

Abstract: The invention relates to an appliance comprising a water tank, a housing including a chamber having an opening for receiving a fill of brew preparation, a chamber closure part having an outflow orifice and mounted to move between an open position and a closed position; means connected to the tank to act during a brewing cycle to deliver a certain volume of water raised to a brewing temperature, from said tank to said chamber. According to the invention, the appliance essentially consists in a portable structure comprising a head containing at least one chamber, a body including at least handle means making it possible, during the brewing cycle, to place the outflow orifice facing down towards a cup.
