ABSTRACT:
A generator system having an auxiliary forced cooling-oil lubrication system in which a second pump for the fluid is driven in a self sustaining cooling and lubricating cycle, despite the failure of a primary pump action. The second pump can be electrically or mechanically driven to cause a reserve portion of the cooling-oil lubricant to recycle from a secondary reservoir. This secondary reservoir reserves a fluid capacity not circulated by gravity feed in a primary fluid circulating path, which normally returns the fluid to a primary reservoir. A primary pump circulates the fluid through a primary portion of a heat exchanger with an oil-to-fuel heat exchange transfer to sustain the cooling and lubricating functions of the generator system and the failure mode, second pump sustains cooling operations of a permanent magnet generator, despite the failure of a primary pump or loss of fluid circulating in the primary circulation path.
