Abstract
A lubrication system for the intermittent lubrication of a lubrication target, comprises a lubrication emitter having structure for generating a series of lubrication liquid droplets and carrying the droplets along a travel path by a propellent gas stream issuing from the emitter, a lubrication target located in a spaced relationship from the emitter within the travel path and a moving barrier located proximate the emitter between the emitter and target and in a non-contact relationship with the emitter. The barrier generates an intermittent disturbance to the propellent gas stream whereby the carrying of the droplets by the propellent gas stream is prevented during the time interval of the disturbance. Carrying of the droplets by the propellent gas stream occurs during the time interval in which the disturbance ceases. The barrier can take the form of a disc or a shell surrounding the target. The solid surface of the disc or shell generates the disturbance, while one or more apertures in the solid surface interrupt the generation of the disturbance.
