Abstract

La présente invention concerne un instrument d'écriture hautement fiable de fabrication simple, conçu de manière à ce que lorsque l'on arrête d'écrire, l'encre qu'il contient ne peut être expulsée excessivement dans un corps de stylo (5). Cet instrument d'écriture comprend une petite cavité d'arrêt (11) contenant de l'air hermétique, formée entre une cavité d'encre et le corps du stylo (5). Des noyaux de relais résistants (14, 21) associés à la cavité d'encre et au corps du stylo sont introduits respectivement dans un passage d'alimentation associé à la cavité d'encre (12) établissant une voie de communication entre la cavité d'arrêt et la cavité d'encre (2), et dans un passage associé au corps du stylo (13) établissant une voie de communication entre la cavité d'arrêt et le corps du stylo (5). Ce dispositif est conçu de sorte que la pression négative produite par le passage de l'encre permet à l'air contenu dans la cavité d'arrêt (11) de subir une détente pour que, une fois l'écriture achevée, la compression de l'air ramène vers l'arrière une petite quantité d'encre depuis le corps du stylo (5).
