A method and an apparatus for making beverages, such as coffee, soup, tea, or the like, wherein a starting product, such as ground coffee, is supplied to a cavity and is enclosed therein by a piston. After this, through an opening provided in the piston, a quantity of fluid, in this case water, originating from a water system is pressed into said cavity. Hereafter, the fluid, after extraction of the starting product contained in the chamber, in this case filling chamber, is discharged through an opening near the end opposite the piston, the control of this process taking place electronically. The method is characterized in that use is made of an apparatus having at least two filling chambers of different size and mounted on a movable holder and that the various steps are performed during a single cycle of the holder.

Apparatus for making a batch of beverage such as coffee by liquid extraction from a charge of starting product such as ground coffee, comprising: a shaft; a housing having a part which is mounted for rotation about said shaft; said housing part containing at least two chambers of mutually differing volumetric capacity; each chamber being defined by an end wall and a peripheral sidewall having a circumferential edge at an end opposite to that where said end wall is located; means defining an axial opening through said end wall; a respective piston axially slidably disposed in each said chamber and connected with a respective supply tube which penetrates the respective said end wall through the respective said axial opening; each said supply tube having an internal longitudinal bore; means defining an opening through each piston for communicating the respective said chamber, beyond the respective said piston, with the respective said supply tube bore; a liquid supply system arranged for selective connection with each said supply tube bore for forcibly supplying a charge of liquid to the respective chamber; a respective removable cover for each chamber, which can be closed against the respective said circumferential edge for choosing the respective chamber; means defining a respective outlet opening from each chamber on an axially opposite side of the respective said piston from the respective said supply tube, each said outlet opening being arranged to be selectively opened during a time when the respective said chamber is closed by the respective said cover; means for closing and opening each said chamber using the respective said cover, depending upon angular positioning of said housing part about said shaft; means for thrusting and retracting each said piston relative to the respective said chamber, depending upon angular positioning of said housing part about said shaft; whereby, for making a batch of beverage, said housing part may be rotated so as to bring a respective said chamber of selected volumetric capacity to a charging station, at which that chamber, with the respective said cover removed, is filled with a charge of starting product, whereupon the respective cover is closed and extraction liquid introduced through the respective supply inlet bore into contact with the starting product, a resulting batch of beverage drained from the respective chamber through the respective outlet opening, and said housing part rotated to bring the respective said chamber to a discharging station, at which that chamber, with the respective said cover again removed is emptied of its charge of now-spent starting product, at least in part by being pushed out by the respective said piston.
