Abstract: A machine (1) for preparing a beverage comprises: an ingredient processing module (10) for processing at least one ingredient, in particular an ingredient supplied within a capsule (2) into the module; a sensing arrangement (70, 70?) for sensing a user-request by a user-actuation of the sensing arrangement; and a control unit (60) containing different control programs for controlling the ingredient processing module executable on corresponding user-requests. The sensing arrangement (70, 70?) and the control unit (60) are so arranged that each of said different user-requestable control programs is executed on a generally identical user-actuation of the sensing arrangement (70, 70).

Abstract: A pump (800) for a beverage preparation machine (1) has: a pump inlet (810); a pump outlet (820); a liquid driver (815, 816) for pressurising and circulating a liquid from the pump inlet to the pump outlet; and a downstream pump conduit (870, 871, 872) connecting in fluid communication the liquid driver to the pump outlet. The downstream pump conduit comprises a liquid dampener (860) for dampening upstream the pump outlet vibrations in such liquid which are generated by the liquid driver so as to circulate via the pump outlet dampened pressurised liquid from the liquid driver.
