摘要

TITLE OF THE INVENTION: DEVICE FOR RESOLVING DOUBT OF DEPRESSURIZATION OF A GREASER The device (10) for removing doubt of depressurization of a lubricator comprises: - a reception housing (28) of a head (12) of the lubricator configured to prevent movements of the head of the lubricator parallel to an axis (32),- a needle (18) having one end (26) bearing on a valve (13) of the lubricator,- a means (14) for setting the needle in motion towards the receiving housing, parallel to the axis and- an opening (27) for the exhaust of a gas coming from the non-return valve. In some embodiments, the receiving housing (28) comprises two parallel rails for guiding and retaining the head (12) of the lubricator (11) and a stop (38) at one end of the guide rails. In some embodiments, the device comprises an internal moving part (19) of which one face (40), provided with a seal (25) in the form of a closed curve, opens into the receiving housing (28).
