Abstract

La présente invention concerne une pompe volumétrique 100 pour matière visqueuse comprenant au moins un moyen de dosage 19, ledit au moins un moyen de dosage 19 comprenant un piston de dosage 3 mobile dans une chemise 17, ledit au moins un moyen de dosage 19 ayant une phase de pré-compression intervenant entre une phase d’admission et une phase de refoulement, ladite phase de pré-compression étant réalisée par une course C dudit piston de dosage 3, ladite course C permettant d’équilibrer les pressions internes de ladite pompe volumétrique 100 pour obtenir un débit de sortie le plus élevé et le plus régulier possible. Figure d’abrégé : Fig. 1The present invention relates to a positive displacement pump 100 for viscous materials comprising at least one metering means 19, said at least one metering means 19 comprising a metering piston 3 movable within a sleeve 17, said at least one metering means 19 having a pre-compression phase occurring between an intake phase and a discharge phase, said pre-compression phase being achieved by a stroke C of said metering piston 3, said stroke C enabling the internal pressures of said positive displacement pump 100 to be balanced to obtain the highest and most consistent possible outlet flow rate.
