  • Patent number: 12209653
    Abstract: A system for a decentralized emergency lubrication system including a dispenser assembly, a pressure supply assembly, a gearbox assembly, and an electronic assembly. Self-contained packaged oil delivery dispensers that generate its own pressure supply independent of a pump. It is possible to design systems of these packaged oil delivery systems which are strategically placed in a gearbox housing to provide the optimal amount of lubrication during a loss of lubrication (LOL) event. The benefit of dispensers driven LoL solution is that the technology is decentralized in nature, meaning that the supply of pressure does not rely on a single pump or the plumbing of nozzles to a pump. Dispensers offer system redundancy as well as the option to place satellite units strategically mounted in a gearbox housing.
