Abstract

L'invention concerne les ensembles de pompage à surcompression. Elle se rapporte à un ensemble de pompage qui comprend un dispositif d'injection qui transmet un courant de fluide à pression relativement faible mais avec un débit très précis. Le dispositif d'injection fonctionne à basse pression et pose peu de problèmes. Il alimente un dispositif d'accumulation qui permet l'alimentation d'une pompe à haute pression, commandée en fonction d'un parametre de la masse de fluide du dispositif d'accumulation. Application à la formation d'un courant de fluide très régulier, pour ensemble d'analyse par chromatographie en phase liquide.
