Abstract

Valve (1) comprising a hollow (3) body (2) and two opposite orifices (4) and (5) between an upper reservoir (8) and a filling container (9). The valve comprises a slide valve (15) for maintaining the vacuum in the upstream section (8) in the absence of a container (9) or in the downstream section (9) while the upstream volume connected to the orifice (4) is not yet under vacuum, a sliding plug (18) to allow filling without the pulverulent material passing through the pipe (19) being able to soil the valve. Application in particular the vacuum transfer of powders for sintered compounds. <IMAGE>
