Noncombustion engine

A noncombustion engine comprising, a flywheel rotatably mounted on its axis;

• a fluid expansion chamber mounted proximate said flywheel;
• a power piston reciprocally mounted in said chamber, the outer end of said piston being in contact with the peripheral portion of said flywheel;
• pressure reduction means connected by a release port, to said expansion chamber for expanding and cooling said fluid;
• a contraction chamber connected via a check valve to said pressure reduction means, spaced from said expansion chamber;
• a recovery piston reciprocally mounted in said chamber, the outer end of said piston being in contact with another peripheral portion of said flywheel;
• means for feeding fluid at a first pressure and temperature into said expansion chamber;
• means for heating said input fluid to an elevated temperature such that the pressure in said expansion chamber increases to force said power piston out of said expansion chamber against said flywheel rotating the same;
• means for opening said release port;
• means for driving said piston back into said expansion chamber to expel and charge said fluid into said pressure reduction means for cooling and reducing the pressure thereof;
• means for charging the so-cooled, reduced-pressure fluid into said contraction chamber to drive said recovery piston outwardly against said flywheel;
• means for further cooling and contracting the fluid within said chamber and means to drive said recovery piston back into said contraction chamber to drive said cooled fluid into said expansion chamber to recommence the power cycle and drive said flywheel.

A method for developing noncombustion engine power comprising;

• feeding a fluid at a first temperature and pressure into an expansion chamber having a reciprocably mounted power piston therein;
• heating the fluid in said expansion chamber to an elevated second temperature and pressure to drive said power piston out of said chamber against a rotatably mounted flywheel to rotate the same;
• opening a fluid release port in said chamber;
• driving said power piston back into said chamber to expel said fluid from said expansion chamber;
• closing said release port, expanding and cooling said fluid;
• feeding said fluid into a contraction chamber having a reciprocably mounted recovery piston therein to fill said chamber and drive said recovery piston out thereof, further cooling said fluid in said contraction chamber;
• driving said recovery piston back into said chamber to expel said fluid from said contraction chamber and drive said fluid into said expansion chamber to recommence the power cycle and thus drive said flywheel.
