Patent ID: 7492052

Claim:
An electrical generator for use in conjunction with a heat exchange system having an evaporator and a condenser adapted for operating on a working fluid, the evaporator having an evaporator intake port for receiving working fluid in a liquid state and an evaporator outflow port for transmission of working fluid in a gaseous state and the condenser having a condenser intake port for receiving working fluid in a gaseous state and a condenser outflow port for transmission of fluid in a liquid state, the generator comprising: a control circuit comprising an electrical storage module and a timing module; a moderator comprising a moderator cylinder having a moderator chamber and first, second and third moderator ports in fluid communication with the moderator chamber, the first moderator port also being in fluid communication with the evaporator outflow port and the third moderator port also being in fluid communication with the condenser intake port, a moderator coil surrounding at least a portion of the moderator cylinder, the moderator coil being in electrical communication with the control circuit, and a moderator piston comprising a magnetic body slidably disposed in the moderator chamber, the moderator piston being capable of translating between a first position wherein the first moderator port and the second moderator port are in fluid communication and a second position wherein the third moderator port and the second moderator port are in fluid communication, a working spool, comprising a working spool cylinder having a working spool chamber and first, second and third working spool ports, the first working spool port being in fluid communication with the second moderator port, the second working spool port being in fluid communication with the condenser outflow port, and the third working spool port being in fluid communication with the evaporator inlet, a working spool coil surrounding at least a portion of the working spool cylinder, the working spool coil being in electrical communication with the control circuit, a working spool piston comprising a magnetic body slidably disposed in the working spool chamber, the working spool piston dividing the working spool chamber into a condenser side volume in fluid communication with the first working spool port and an evaporator side volume in fluid communication with the second working spool port, the working spool piston being capable of translating between a first position in which the second working spool port is in fluid communication with the condenser side volume and a second position wherein the second working spool port is closed, wherein the first working spool port is configured and positioned so that when pressurized fluid is received through the first port, the pressurized fluid causes the working spool piston to translate from the first position to the second position.
