Abstract

Un instrument pneumatique comprend une structure cylindrique (1) dans laquelle est placée un amortisseur pneumatique, lequel se compose de trois cylindres coaxiaux (32, 33, 34) interconnctés ayant des diamètres d1<d2<d3. Le premier cylindre (32) est creux et il est relié par une soupape de démarrage (21) au conduit pneumatique (24). Le second cylindre (33) forme, par sa face terminale (37) et la paroi interne de la structure (1), la première chambre de puissance (38). Le troisième cylindre (34) forme, par sa face terminale (40) et la paroi interne de la structure (1), la seconde chambre de puissance (41), et il vient au contact d'une poignée (4) au niveau de son autre face terminale (42). Un canal relie les première et seconde chambres de puissance (38, 41) lors du déplacement de la poignée (4) dans le sens de la pointe (9). Le premier cylindre (32) est doté de trois orifices (35, 39, 47) reliant les chambres de puissance (38, 41) au conduit pneumatique (24).
