  • Actuator element of a hydraulic fluid-operated railway track lubricating system
    Patent number: 6464039
    Abstract: A retrofit for an actuator element in a railway track lubricating apparatus for applying lubricant to a rail of a railway track includes a housing with a chamber, an enclosure block, a spacer element for occupying the space in existing actuator elements, 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.
