A filling apparatus of flexible containers with a dense fluid, such as cream, yoghurt, honey, fruit juice, medicines and similar comprises vacuum devices, gas supply devices, filling devices and a valve. The valve comprises a main body, an obturator, a needle and a needle operating mechanism able to move the needle in translation. The obturator duct is connected to the vacuum and gas supply devices, to remove any residues of fluid aspirated.

1. An apparatus for filling flexible containers with a dense fluid such as cream, yoghurt, honey, fruit juice, and medicines, comprising: a vacuum device able to generate a vacuum by suction;a gas supply device, able to supply a pressurised gas;a filling device, able to supply a dense fluid;a valve
1. An apparatus for filling flexible containers with a dense fluid such as cream, yoghurt, honey, fruit juice, and medicines, comprising: a vacuum device able to generate a vacuum by suction;a gas supply device, able to supply a pressurised gas;a filling device, able to supply a dense fluid;a valve comprising: a) a main tubular body having a main inner compartment, connected to the filling device, and a main duct able to engage a straw of the container; b) an obturator sliding in the main body between a forward position in which it closes off communication between the main duct and the main compartment and a retracted position, in which it allows communication, in which the obturator has an inner obturator duct and an obturator hole; c) a needle slidable in the obturator duct between a retracted, closed position in which it closes the obturator hole and a forward open position, in which the obturator hole is open; d) needle operating means able to move the needle in translation; wherein the obturator duct is connected to the vacuum device and the gas supply device, to remove any residues of fluid aspirate; and wherein the valve comprises an obturator security device able to constantly bias the obturator from the retracted position to the forward position, and a needle return mechanism able to constantly bias the needle from the forward, open position to the retracted, closed position. 2. Apparatus according to claim 1, wherein the needle operating means comprises a double-acting cylinder piston group. 3. Apparatus according to claim 1, wherein the obturator security device comprises an obturator spring. 4. Apparatus according to claim 3, wherein the spring is engaged with the obturator at the end opposite that facing the main duct and at the other end abuts against an annular boss which projects inwards from the main body. 5. Apparatus according to claim 1, wherein the needle projects from the obturator through the obturator hole and has an enlarged head shaped so as to close the obturator hole when abutting with the obturator and smaller than the main duct so as to form a passage when inserted in it. 6. Apparatus according to claim 1, wherein the needle return mechanism comprises a needle spring. 7. Apparatus according to claim 6, wherein the needle return mechanism comprises a cup attached to the needle and wherein the needle spring can be compressed between the obturator and the cup. 8. Apparatus according to claim 1, wherein the obturator is made in polymeric material. 9. Apparatus according to claim 1, wherein the valve is free of sealing bands between the obturator and the needle or between the obturator and the main body. 10. An apparatus for filling flexible containers with a dense fluid such as cream, yoghurt, honey, fruit juice, medicines and similar, comprising: a vacuum device able to generate a vacuum by suction;a gas supply device able to supply a pressurised gas;a filling device able to supply a dense fluid;a valve comprising: a) a main tubular body having a main inner compartment, connected to the filling device, and a main duct able to engage a straw of the container; b) an obturator slidable in the main body between a forward position in which it closes off communication between the main duct and the main compartment and a retracted position, in which it allows communication, in which the obturator has an inner obturator duct and an obturator hole; c) a needle slidable in the obturator duct between a retracted, closed position in which it closes the obturator hole and a forward open position, in which the obturator hole is open; wherein the obturator duct is connected to the vacuum devices and the gas supply device, to remove any residues of fluid aspirated; and wherein the obturator is made in polymeric material and the valve is free of sealing bands between the obturator and the needle or between the obturator and the main body.
