  • Patent number: 4467892
    Abstract: Microlubrication system to divide and distribute a flow of lubricant automatically to one or more machines needing lubrication. Fail-safe, accurate distribution is provided by diverting flow of lubricant from the distribution system most of the time, allowing lubricant to be distributed only at intervals. When the lubricant is being distributed, it flows at a high enough rate to allow accurate metering and division of flow, but the overall delivery rate is low enough to prevent wasting the lubricant. The system is preferably provided with fail-safe means to ensure lubrication or to shut off the machines to be lubricated in the event lubrication fails and cannot be quickly restored.
