Abstract

L'invention concerne un convertisseur hydraulique d'énergie, comprenant une came 6 et un bloc cylindres 8 dont les alésages 30 contiennent un piston 38 présentant un poussoir de came 42. Chacun des alésages 30 comprend un moyen limitateur 44, constitué par une bague élastique. Ce moyen limitateur 44 peut s'engager dans une cavité de la surface en retard afin d'empêcher le poussoir de came 42 de venir en contact avec la came 6 aussi longtemps qu'une force résultante de poussée du piston est inférieure une valeur critique. Applications : moteur et pompes à pistons radiaux.The invention relates to a hydraulic energy converter, comprising a cam 6 and a cylinder block 8, the bores 30 of which contain a piston 38 having a cam plunger 42. Each of the bores 30 comprises a limiting means 44, constituted by an elastic ring. . This limiting means 44 may engage in a cavity of the lagging surface to prevent cam pusher 42 from contacting cam 6 as long as a resulting piston pushing force is below a critical value. Applications: radial piston engine and pumps.
