ABSTRACT:
An improved dividing assembly, useful in dividing the high pressure gas system from the lubricating system in a regenerative type Stirling engine, is disclosed. The closed thermally cycled gas system of a Stirling engine may vary between 20-200 atmospheres which complicates sealing and separation problems between fluid systems in the engine. One interface between said fluid occurs at the piston rods which reciprocate between an oil flushed environment within the driven assembly and the pure high pressure gas environment of the thermal cycling assembling. The two systems must be separated and yet allow access of each system to said rods. A piston rod sealing assembly is employed which uses a bleed of high pressure gas to (a) assist in forcing a tighter wiping of the piston rod surfaces, and (b) to convey wiped oil as a mixture away from the sealing assembly. A separator assembly is employed to reclaim substantially pure gas from said mixture and return separated oil to the oil system. A control periodically returns separated oil; the float element of the control withstands high pressures of the fluids worked upon by use of a condensate confining zone within the float and an intercommunication between such zone and the float exterior so that upon the occurrence of a pressure differential between the float interior and exterior, oil residue may be ejected and placed with oil separated by other filter or demisting means.
