Title
(EN) A SUPPRESSOR FOR A GUN
(FR) SILENCIEUX POUR ARME À FEU
Abstract
(EN)
A suppressor for a firearm comprises an inner chamber providing a gases inner flow path and an outer chamber providing a parallel gases outer flow path. The suppressor is configured so that gases pressure between the inner chamber and the outer chamber is balanced along the length of the inner and outer chambers so that gases exhaust from the inner and outer chambers at substantially the same time.
(FR)
L'invention concerne un silencieux destiné à une arme à feu qui comprend une chambre interne fournissant un trajet d'écoulement interne de gaz et une chambre externe fournissant un trajet d'écoulement externe de gaz parallèles. Le silencieux est conçu de telle sorte que la pression de gaz entre la chambre interne et la chambre externe est équilibrée le long de la longueur des chambres interne et externe de telle sorte que les gaz s'échappent des chambres interne et externe sensiblement en même temps.
