Abstract

La présente invention concerne une structure de lubrification de bague d'étanchéité dans un dispositif de transfert de revêtement comprenant : une vanne (1), et un clapet de non-retour d'entrée de revêtement (2), un clapet de non-retour de sortie de revêtement (3), et une tige de piston de poussée (11) disposée dans la vanne (1). Une chambre interne de la vanne (1) communique, de façon unidirectionnelle et respectivement, avec le clapet de non-retour d'entrée de revêtement (2) et le clapet de non-retour de sortie de revêtement (3). Une extrémité de la tige de piston de poussée (11) est rendue étanche par une bague d'étanchéité et est disposée dans la chambre interne de la vanne (1) de façon à pouvoir se déplacer vers la gauche ou vers la droite. L'autre extrémité de la tige de piston de poussée (11) s'étend hors de la vanne (1) et est reliée à un dispositif d'entraînement de la tige de piston de poussée (11). Une chambre de stockage d'huile lubrifiante (13) est disposée dans la vanne pour stocker un lubrifiant. L'huile dans la chambre de stockage d'huile lubrifiante (13) s'écoule par l'intermédiaire d'un trou traversant (14) vers la périphérie de la tige de piston de poussée (11) entre une bague d'étanchéité avant (12) et une bague d'étanchéité arrière (15). Un trou d'injection d'huile est prévu au niveau de la chambre de stockage d'huile (13), communique avec l'extérieur pendant l'injection d'huile, et est fermé à l'extérieur lorsque l'huile n'est pas injectée.
