CA 2346428

The invention concerns a novel method for producing discharge chambers, in particular for flat silent projectors. Said method consists in inserting a pumping rod (3) used for emptying and filling the discharge chamber into an opening (2) thereof, thereby obtaining in simple manner, through an intermediate component, optimal adjustment as well as optimal tightness between the inner angular walls of the opening (2) and the round outer part of the pumping rod (3).

L'invention concerne un nouveau procédé mis en oeuvre dans la production d'enceintes à décharge, en particulier pour projecteurs plats silencieux. Selon ledit procédé, une tige de pompage (3) utilisée pour vider et remplir l'enceinte à décharge est insérée dans une ouverture (2) de celle-ci. On obtient, de façon simple, grâce à une pièce intermédiaire (4), un ajustage optimal et une étanchéité également optimale entre les parois intérieures angulaires de l'ouverture (2) et la partie extérieure ronde de la tige de pompage (3).
