ABSTRACT:
A system for recirculating sealing liquid back into the liquid seal portion of a Stirling engine is disclosed. The system uses two pumping devices alternatively coupled to an accumulation reservoir to receive escaped liquid and to return it to the liquid seal. As sealing liquid accumulates, it is selectively pumped into one pumping device, while the other is discharging previously accumulated liquid. The system is then switched so that the operation of the two pumping devices is reversed.
