Hi everybody! I'm working on a technical manual of a French heat pump and I can't understand the meaning of lanceur in the following sentence:

" [...] Les circulateurs se mettent en fonctionnement pour permettre le dégazage de l'installation. Si ce n'est pas le cas, après avoir retiré le bouchon du lanceur à l'aide d'un tournevis à large lame, dégommer le circulateur".

Any idea? Everything I found on dictionaries seems not suitable for this context.

  • "un lanceur" is usually an equipment which is only used for the start of an engine or another device. You could call it a "starter" I guess (in English, because this name does exist in French and doesn't mean the same thing).
