Abstract

Cette perforatrice est du type comprenant un marteau muni d'un corps 10 et dont le percuteur 15 frappe la tige ou le train de tiges de forage, et dans lequel le corps 10 du marteau est muni d'un ressort à fluide composé d'un piston annulaire 16 coulissant dans une chambre cylindrique 17 contenant un fluide sous pression et solidaire du corps 10, ce ressort exerçant une pression sur un épaulement 34 solidaire de la tige 11. Suivant l'invention, la chambre cylindrique 17 contient un liquide hydraulique et est reliée hydrauliquement à un élément élastiquement compressible 25.
