A lubricator (1) includes a coaxial compartment (3) with a shaped seat (4) upon which a sliding shutter (5) consisting of a front shaped plug (6) and an intermediate stem (7) with a back beat (8) associated with a first stop pin (9), operates; in the rear threaded end (10) of the compartment (3) a security dowel (11) with a front beat (12) associated with a second stop pin (13), screws on. A counter spring (15) engages Itself between pins (9) and (13). The stem (7) of the shutter and the dowel (11) present peripheral helical grooves (14, 14') with a spiral developing in the opposite direction as to the threading (10) of the compartment (3) and the threading of the dowel (11) itself.
La présente concerne un lubrificateur (1) qui comprend un logement coaxial (3) muni d'une embase formée (4) sur laquelle repose un obturateur à glissière (5), composé d'une cheville frontale façonnée (6) et d'une tige intermédiaire (7) et d'une butée postérieure (8) jumelée à une première goupille de blocage (9); sur l'extrémité filetée (10) du logement (3), il y a un goujon de sécurité (11) qui se visse, assorti d'une butée antérieure (12) et d'une deuxième goupille de blocage (13). Un contre-ressort (15) s'engage entre les goupilles (9) et (13). La tige (7) de l'obturateur et le goujon de sécurité (11) comportent des rainures hélicoïdales (14, 14'), dont la spirale va dans la direction opposée au filetage (10) du logement (3) et du filetage du goujon (11) proprement dit.
