ACTUATOR ELEMENT OF A HYDRAULIC FLUID-OPERATED RAILWAY TRACK LUBRICATING SYSTEM
Document Type and Number:
WIPO Patent Application WO2002020327
Kind Code:
A9
Abstract:
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).
