Abstract

Machine avec régulateur et soupape de limitation de pression commandés par une soupape pilote. La machine, par exemple une pompe à pistons radiaux, est réglée par les pistons 11 et 12. La pompe refoule dans la tubulure 13, avec une dérivation 14 vers le piston 11, puis dans la tubulure 15 avec une dérivation en 16 vers la soupape 18 de régulation de pression commandée par la tubulure 19, et en 17 vers une soupape 21 de limitation de pression menant à une tubulure basse pression 22. La dérivation 23 comporte un étranglement 23. La tubulure 24 mène à une soupape pilote 25. Les soupapes 18, 21 et 25 sont poussées respectivement par les ressorts 29,27 et 31. Le repère 26 désigne une tubulure de commande, 33 est un réservoir de décharge.
