Abstract

L'invention concerne une pompe à pistons 2 partiellement immergée. La pompe est caractérisée par le fait que chaque ensemble chemise 3 et piston 2, constamment écartés par un ressort 16, forme un tout mobile maintenu coincé entre une rotule femelle 18, comportant l'orifice de refoulement 15, 21, 23 et un excentrique 6 calé sur l'arbre de commande 5. Le fond borgne 8 de la chemise 3 présente un conduit d'aspiration 10 latéral constamment immergé dans le fluide hydraulique et débouchant sous le siège d'un clapet 12. Application aux pompes de dispositifs hydrauliques.
