Abstract:
A rotary liquid piston engine which converts the enthalpy of a two-phase fluid into rotary motion,said engine comprising a bi-phase fluid expanding assembly having an intake and an exit,bearings and axles mounting said assembly to a frame such that said expanding assembly can rotate with respect to a body forcepiping means providing a delivery of a bi-phase fluid to the intake of the assembly and removing it from the exit,coupled shafts and gearing which allow the motion of the assembly to do work, said bi-phase fluid expanding assembly consisting of: a rigid cylinder containing a plurality of cavities continuous from the fluid intake to the exit, said cavities being positioned and shaped such that said body force creates a sequence of potential energy minimums along each cavity, the liquid component of the bi-phase fluid being confined to the potential minimums of the body force consequently confining the vapor component between said cavities,said cavities being positioned and shaped such that, when rotated with respect to the body force the potential minimums move towards the exit,the volume between liquid pistons increases with motion towards the exit decreasing the pressure, an unbalanced pressure on the cavity walls results in torque being generated about the axis, and the fixed liquid component moves in the cavities, expands and allows the performance of work through said coupled shafts and gearing.
