Abstract

See full text

A control device for the closing and opening of the extraction chamber (5) of a coffeemaking machine of the espresso type. The extraction chamber (5) comprises two parts (3, 4) movable relative to each other by an electric motor (6) to open or close the extraction chamber (5). The device comprises: elements for measuring the intensity of the supply current of the motor (6) at least during the closing phase of the extraction chamber (5); elements for detecting a drop in the derivative relative to the current supply time below a predetermined threshold, permitting detecting the optimum closed position for the extraction chamber (5), so as to stop the movement of the movable parts (3, 4) when this position is reached.
