Abstract

Chalumeau comportant un mécanisme perfectionné d'avance de la baguette d'amorçage. Le mecanisme M comporte un piston 25 qui coulisse dans une chambre 13 sous l'action d'une impulsion de gaz arrivant par un conduit 19 d'un conduit principal de gaz, par l'intermédiaire d'une soupape. Le piston est ramené automatiquement en position de départ. Ce mécanisme est conçu de manière à éviter la présence d'oxygène à proximité de la flamme pendant la coupe. Application : chalumeaux découpeurs et décriqueurs.
