Machine for filling vessels with two products

A machine for filling vessels comprising at least two tanks for the storage of two filling products, and at least one filling station comprising a filling nozzle and a volumetric metering system, said volumetric metering system comprising

• a cylinder, defining a metering chamber, provided with a suction and discharge piston driven by first actuation device, and provided in the lower portion with a first suction opening connected by a first suction duct to a first storage tank, with a second inlet opening connected by a second suction duct to the second tank, and with a discharge opening connected by a discharge duct to the filling nozzle;
• and
• valve systems able to be driven by second actuation device in order to selectively put the metering chamber in fluid communication with one or more of the first tank, the second tank and the filling nozzle,
• said valve systems including a first valve system and a second valve system mounted respectively in the first suction duct and the second suction duct, and a third valve system arranged on the filling nozzle,
• each valve system being driven individually for opening and for closing by second individual pneumatic and/or electrical actuation device connected to a parametrisable control unit of the machine,
• said suction and discharge piston being driven by electric or pneumatic actuation device connected to said control unit.
