Abstract

Cette pompe est du type de celles comportant au moins un plongeur coulissant dans le corps de pompe. Dans la pompe selon l'invention, il est prévu dans le corps de pompe 1 ou dans une pièce 3 solidaire de ce dernier, un espace annulaire 6 ouvert en direction du plongeur 2, apte à être rempli d'un liquide d'étanchéité ayant une viscosité supérieure à celle du fluide déplacé par la pompe, alimenté par un conduit 23 qui débouche dans un cylindre où coulisse un piston 26 délimitant une chambre 27 séparée du conduit d'alimentation, qui communique par un canal 28 avec la chambre de refoulement 29 de la pompe.
