Abstract

Dispositif de lancement pneumatique pour tirer un projectile (2) à partir d'un tube de lancement (3) relié à un système d'air sous pression comportant au moins un réservoir à fluide sous pression secondaire (5), au moins un dispositif de réglage (13) servant à fixer la position du projectile (2) à tirer étant situé sur le tube de lancement (3) et une soupape (10) étant située entre le réservoir à fluide sous pression secondaire (5) et le tube de lancement (3). L'objet de la présente invention est de pouvoir régler de manière très précise et reproductible les vitesses de projection des projectiles (2) à l'aide d'un dispositif de ce type. A cet effet, selon une variante préférée, ledit dispositif de lancement (1) est ainsi conçu que le réservoir à fluide sous pression secondaire (5) se trouve en liaison fonctionnelle, par l'intermédiaire d'une soupape (20), avec un réservoir à fluide sous pression primaire, le réservoir à fluide sous pression primaire (6) devant présenter une haute pression et un grand volume et le réservoir à fluide sous pression secondaire (5) devant présenter une pression plus basse et un petit volume. L'ouverture de la soupape (10) précède le déclenchement du tir et le déclenchement du tir se fait seulement ensuite, par actionnement du dispositif de réglage (13).
