Abstract

Cette pompe, du genre pompe à plongeur, comprend un organe 12 tel qu'un piston, soumis à l'action d'un ressort et monté mobile, qui sépare une chambre à ressort 13 de la chambre de refoulement 6 de la pompe Ce piston est soumis, du côté opposé au ressort, à la pression qui règne dans la chambre de refoulement, et il est déplaçable à l'encontre de l'action du ressort pour une pression déterminée à l'intérieur de la chambre de refoulement. Le ressort est avantageusement réalisé sous la forme d'un ressort pneumatique. L'invention s'applique notamment à la technique du soutènement hydraulique.
