Abstract:
1. 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, provided with one suction and discharge piston driven by a first electric or pneumatic actuation device, and having a lower portion where is defined a metering chamber and providing with a first suction opening connected by a first suction duct to a first storage tank filled with a first filling product, with a second inlet suction opening connected by a second suction duct to the second tank filled with a second filling product, 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 or electrical actuation device connected to a parametrisable control unit of the machine, each valve system being formed of a clack valve mounted at the free end of a rod of a jack in order to displace said clack valve between a sealing position and an opening position, said suction and discharge piston being driven individually from each valve system by the first actuation device connected to said control unit and being displaced downward in the metering chamber in order to fill a vessel placed under the filling nozzle with a first quantity of the first filling product and with a second quantity of the second filling product, the volumetric metering system comprises a plate, forming the lower portion of the cylinder, the suction ducts and the discharge duct being formed in the plate, the plate being mounted on the cylinder and forms the lower portion of the cylinder with a recess coming according to the axis of the cylinder, the suction ducts and the discharge duct exiting on the lateral wall of the recess, and on which are mounted the jacks and the dispensing nozzle, said plate being assembled at the bottom walls of the concentric tanks in such a way that some vertical portions of the ducts come to connect to the openings of the bottom walls.
