A retrofit for an actuator element (16) in a railway track lubricating apparatus (10) for applying lubricant to a rail (12) includes a housing with a chamber, an enclosure block, a spacer element for occupying the space in existing actuator elements (16), a T-shaped plunger with a base adjacent a coil spring, and an actuator stem movable in a bore in the top of the housing, and wherein the stem is supported by and in sealed communication with a bushing that is placed within the cavity of the bore. A hydraulic fluid inlet opening is located at the bottom of the housing and a hydraulic fluid outlet opening is located at the top of the housing. A second embodiment provides an actuator element (16) for use in new lubricating systems whereby the actuator element (16) is mounted onto the rail (12) and does not involve a spacer element in the chamber of the actuator element (16).

La présente invention concerne un accessoire pour actionneur (16) de lubrificateur (10) de voie de chemin de fer (12). Cet accessoire se compose d'un carter définissant une chambre, un bloc enceinte, un intercalaire comblant le volume entre les éléments existants (16) de l'actionneur, un piston en T dont une base fait suite à un ressort à boudin, et une tige d'actionneur mobile dans un alésage en tête de carter. Cette tige repose en mode étanche dans une chemise cylindrique montée dans la lumière d'alésage. Un orifice d'admission du fluide hydraulique est situé au bas eu carter, l'orifice de sortie se situant en tête de carter. Un deuxième mode de réalisation de l'invention concerne un élément d'actionneur (16) pour systèmes de lubrification neufs, auquel cas l'élément actionneur (16) se monte sur le rail (12) sans qu'il y ait besoin d'intercalaire dans la chambre de l'élément actionneur (16).
