  • Self-acting self-circulating fluid system without external pressure source and use in bearing system
    Patent number: 8453665
    Abstract: The invention includes a method for continually circulating a fluid in a system, in the absence of an external pumping mechanism, by providing a fluid, an active space capable of generating a higher pressure zone and causing a contiguous lower pressure zone, a passive space, and a porous medium disposed between the active space and the passive space, and generating a pressure differential relationship between the active space and the passive space causing the fluid to circulate freely in both directions between the active space and the passive space, across the porous medium, without the aid of an external pumping system, such that the fluid circulation defines a self-acting self-circulating fluid system, and to the system created thereby.
