Abstract

L'invention est relative à une pompe à piston 9 muni d'un clapet dans le piston. Ce clapet 20 est disposé sur un tronçon de conduit radial 19, qui est ménagé dans le piston et qui débouche dans une rainure 16 du cylindre. Une application est la réalisation d'une pompe ayant un prix de revient faible.
