A filling system includes filling elements, each of which has a channel formed in its housing. During filling, filling material, under a liquid valve's control, passes through the channel and exits through an opening and into a container held on a vertically displaceable container carrier. During pressure filling, the container carrier seals the container against the filling element. During cleaning and sterilization, rinsing caps seal each opening. Each filling element is associated with an extension that seals the outlet. Each extension has a filling-material through-passage that, when the extension is sealed against said outlet, extends the filling-material channel.

A device includes a rotary portion, which is mounted so as to rotate on a support structure around a rotation axis (X-X) between an angularly moved away condition and an angularly moved close condition relative to an outlet mouth. A shutter portion pivots relative to the rotary portion around a pivoting axis (Y-Y) lying on a plane that is transverse relative to the rotation axis (X-X). An actuating apparatus moves the rotary portion between the moved away condition and the moved close condition. The shutter portion is suited to pivot around the pivoting axis (Y-Y) from an open position, in which the shutter portion is spaced apart from the outlet mouth, to a closed position, in which the shutter portion lies against the outlet mouth, when the rotary portion shifts from the moved away condition to the moved close condition.

An injection device having an inlet, an outlet and a chamber extending between the inlet and the outlet. A piston divides the chamber into an upper chamber and a lower chamber. The piston is movable within the chamber and includes a body. The piston includes a shutter movable with respect to the body between a closed position, wherein the body and the shutter isolate the upper chamber from the lower chamber when the piston is moved in an injecting direction, and an open position, wherein the body and the shutter place the upper chamber in fluidic communication with the lower chamber when the piston is moved in a filling direction.

An apparatus for filling containers with a filling material includes a transport element that rotates in a transport direction, filling positions formed on the transport element, and a common carrier common to all positions and moving with the transport element. Each filling position has a filling element, a weighing cell secured to the carrier, a container carrier, and a functional element assigned to the filling position on the common carrier. The common carrier is adjustable to move by an adjustment unit either in or opposite to the transport direction. The adjustment unit corresponds to a distance between functional elements of filler positions that are adjacent to each other in the transport direction.

An apparatus for filling containers comprises a filling station, with a plurality of filling heads which are supplied by supply ducts supplying a filling fluid and are each provided with a dispensing nozzle. The apparatus has a number of collection cups for collecting washing fluids for washing the filling heads and the supply ducts, equal to the number of said filling heads.
