Abstract

L’appareil à percussions comporte un dispositif de régulation de pression (16) comprenant un cylindre de régulation (17) ; un canal de liaison (23) débouchant dans le cylindre de régulation (17) ; un tiroir de régulation de pression (18) monté mobile en translation dans le cylindre de régulation (17) et délimitant, avec le cylindre de régulation (17), un passage de liaison (24) ayant une section de passage qui varie en fonction de la position de régulation occupée par le tiroir de régulation de pression (18) ; un élément de sollicitation (26) configuré pour exercer une précontrainte sur le tiroir de régulation de pression (18) ; et un dispositif de réglage de précontrainte (27) configuré pour régler une précontrainte exercée par l’élément de sollicitation (26) sur le tiroir de régulation de pression (18).
