Modular lubricating system and injector

摘要

A lubricating system for delivering charges of lubricant and air for aerifying the lubricant to multiple points of lubrication. The system comprises a series of air-operated lubricant injectors each of which is operable in response to delivery thereto of operating air to deliver a charge of lubricant. The injectors are organized in a row in engagement with one another. Each injector has a lubricant passage extending through it, the lubricant passages in the injectors being in end-to-end communication with one another to form a lubricant manifold extending through the row for receiving lubricant and charging the injectors. Each injector also has first and second air passages therein, the first air passages being in end-to-end communication with one another and forming a first air manifold for receiving injector operating air and delivering it for operating the injectors, and the second air passages also being in end-to-end communication with one another and forming a second air manifold for receiving air for aerifying the charge of lubricant delivered by the injectors.
