ABSTRACT:
The automatic machine for the production of coffee and infusions according to this invention comprises a filter-carrying element having on the base a movable filter for the filtration of the infusion of coffee, into which element there can be sealingly inserted a piston equipped with means for the delivery of hot water under pressure supplied from a metering unit, in which the piston is carried by a transverse bar extending between two parallel side members of the machine and equipped with a pair of connecting rods adjacent to the lateral members and associated with elastic means for exerting tension on the piston and connected eccentrically to respective discs which can be rotatably actuated by a geared motor, there being present means for friction blocking of the piston in a lowered position in the filter-carrying element, these means determining the irreversible transmission of the movement from the motor to the piston, means being also present for the automatic expulsion of the exhausted infusion substance and for cleaning of the surfaces in contact with it.
