ABSTRACT:
Three operating chambers, each having an electric heating element therein and simultaneously operated solenoid inlet and outlet valves, are arranged to operate in sequence, each operating chamber having a power piston in communication therewith that engages the driving end of a separate fulcrumed power arm. The three power arms are arranged to jointly rotate a crank shaft through three crank arms, to produce power for operating generators and the like. At the start of an operating cycle for each operating chamber, it is filled with cold starting liquid from a refrigeration unit. The electric heater element is activated for a precise time period to heat and expand the liquid to operate the power piston, and thereafter the inlet and outlet valves are operated to drain the heated liquid and replace it with cold. A control circuit driven from the crankshaft operates the heater elements and the solenoid valves in a precise timed sequence, to ensure maximum efficiency and smooth power output.
