FIELD: personal use articles.
SUBSTANCE: invention related to improvements in beverage preparation devices. The brewing module for beverage preparation contains a movable element (9) with a socket (15) for ingredients for preparation of the above beverages, forming a brewing chamber and designed so that to enable movement from the ingredient charging position into the brewing position; while in the said brewing position, the said socket (15) is positioned between the hot water supply device (41) and the beverage output tip (35) that are mutually opposed; the said supply device (41) contains an actuator element (43, 47) of cylinder piston type whereto the first tube (48) supplying water under pressure is connected that controls the locking movement of the supply device towards the said socket (15) into the brewing position; the said cylinder piston actuator element includes an external cylinder (43) and a piston (47) skidding in the said external cylinder (43); the piston (47) of the said cylinder piston actuator element is connected to the pipeline (57) supplying water under pressure and includes a hot water supply chamber (55) with at least one hole (53B) for hot water supply onto the brewing chamber closing surface (53A) positioned on the first side of the said piston (47); the piston (47) contains a body (47C) and forms a pressure surface (47A) exposed to water supplied into the cylinder (43) of the cylinder piston actuator element; the said pressure surface (47A) is positioned on the second side of the said piston that is opposed to the above first side; mounted on the piston 47) is a valve (61) for closing the hole (53B) serving for supply of hot water onto the brewing chamber closing surface (53A); the valve is opened under the action of hot water in the hot water supply chamber (55) thus establishing fluid medium communication between the hot water supply chamber (55) and the hot water supply hole (53B).
EFFECT: improvement of beverage preparation brewing module.
