Abstract

L'invention concerne une pompe hydraulique à deux vitesses. Elle se rapporte à une pompe hydraulique à deux vitesses comprenant deux pistons 82, 100 qui sont coaxiaux et placés l'un dans l'autre, la section efficace du piston 82 à basse pression étant beaucoup plus grande que celle du piston 100 à haute pression. Des clapets de retenue sont sous forme de modules interchangeables, comprenant une bille et un ressort placés dans une cavité délimitée par un cylindre amovible. Application aux outils de sertissage de câbles.The invention relates to a two-speed hydraulic pump. It relates to a two-speed hydraulic pump comprising two pistons 82, 100 which are coaxial and placed one inside the other, the effective section of the piston 82 at low pressure being much greater than that of the piston 100 at high pressure. . Check valves are in the form of interchangeable modules, comprising a ball and a spring placed in a cavity delimited by a removable cylinder. Application to cable crimping tools.
