Abstract: The coffee maker for brewing powder coffee contained in a cartridge comprises a brewing chamber adapted to receive the cartridge, at least one punching member for punching the cartridge and a pump for feeding brewing water into the brewing chamber. In order to avoid that the prepared coffee shows froth at its surface, the coffee maker comprises means for restricting the amount of water fed by the pump into the brewing chamber per unit of time. This means ensures that the brewing water flows through the cartridge essentially unpressurized.

Abstract: A capsule for preparing drinks by passing a liquid through a powdered substance (9) contained in a chamber (8) made in the capsule (1). The chamber (8) is delimited on at least one side by at least one filter element (7) having a plurality of through-holes (12) extending from a first face (13) of the filter element (7) facing the inside of the chamber (8), to a second face (14) of the filter element (7). At least at the first face (13), the through-holes (12) have inlet sections (15) extending according to a main trajectory of extension and each having a length, measured along the main trajectory of extension, greater than their width, measured transversally to the main trajectory of extension.
