Abstract

L’invention concerne une sonde de reniflage (3) pour détecteur de fuites (1) pour le contrôle de l’étanchéité d’un objet à tester par gaz traceur, la sonde de reniflage (3) comportant un embout (14) comprenant un orifice d’entrée (15) et un orifice de sortie (16), caractérisée en ce que l’embout (14) comporte une cavité de retenue (18) ayant une ouverture située face à l’orifice d’entrée (15), une chambre (19) communiquant avec l’orifice de sortie (16), la chambre (19) étant configurée pour recevoir un filtre (20) pour filtrer les gaz pompés traversant la chambre (19), et au moins un orifice latéral (22) ménagé dans une paroi latérale de la cavité de retenue (18) pour mettre en communication la cavité de retenue (18) avec la chambre (19). La présente invention concerne également un détecteur de fuites. Figure d’abrégé : 2The invention relates to a sniffer probe (3) for a leak detector (1) for checking the tightness of an object to be tested by tracer gas, the sniffer probe (3) comprising a tip (14) comprising a inlet port (15) and an outlet port (16), characterized in that the end piece (14) comprises a retaining cavity (18) having an opening located opposite the inlet port (15), a chamber (19) communicating with the outlet port (16), the chamber (19) being configured to receive a filter (20) for filtering the gases pumped through the chamber (19), and at least one side port (22 ) formed in a side wall of the retaining cavity (18) to put the retaining cavity (18) in communication with the chamber (19). The present invention also relates to a leak detector. Abstract figure: 2
