Abstract:
A lubricating system comprising an assembly of first and second groups of air-operated lubricant injectors with an air pressure regulator interposed between the groups, each injector being operable in response to delivery thereto of operating air to deliver a charge of lubricant, the injectors in each group being held in assembly in engagement with one another, each injector having a lubricant passage extending therethrough, the lubricant passages in the injectors being in end-to-end communication one with another and constituting a lubricant manifold extending through each group for receiving lubricant and charging said injectors, each injector also having a first air passage extending therethrough, the first air passages in the injectors being in end-to-end communication with one another and constituting a first air manifold extending through each group for receiving operating air and delivering it for operating the injectors, each injector having a second air passage for air for aerifying the charge of lubricant delivered thereby for delivery of the lubricant charge and aerifying air for spraying the lubricant on a point of lubrication, the second air passages in the first group of injectors being in end-to-end communication with one another and constituting a first aerifying air manifold extending through the first group, the second air passages in the second group of injectors being in end-to-end communication with one another and constituting a second aerifying air manifold extending through the second group, the first aerifying air manifold being in communication with the second aerifying air manifold via said air pressure regulator for reduced aerifying air pressure in the second aerifying air manifold.
