摘要： Multiphase electromagnetic machines, such as free-piston engines or compressors, may require, or supply, a pulsed power profile from or to a DC bus, respectively. The pulsed power profile may include relatively large fluctuations in instantaneous power. Sourcing, sinking, or otherwise exchanging power with an AC grid, via an inverter, may be accomplished by using an energy storage device and a DC-DC converter coupled to a DC bus. The energy storage device may aid in smoothing the pulsed power profile, while the DC-DC converter may aid in reducing fluctuations in voltage across a DC bus due to energy storage in the energy storage device.

摘要： This Invention relates generally to the free-piston type internal combustion engine, using air by compressing the air, moving the compressed air outward onto the flywheel vane 244, therefor moving the flywheel 240 in a rotary motion. Transferring energy from the flywheel 240 directly to the drive shaft 246. The piston 138 move fore and aft, within the cylinder 112, from the combustion chamber 1 118 to the combustion chamber 2 128. The piston arm 1 148, attached to the piston 138 at one end, the air piston 1 172 at the other end, resulting in the fore and aft movement of the air piston 1 172. The piston arm 2 154, attached to the piston 138 at one end, the air piston 2 178 at the other end, resulting in the fore and aft movement of the air piston 2 178. The air piston 1 172 move fore on the outward stroke and aft on the inward stroke compressing the air, the compressed air is pushing and pulling the flywheel vane 244 in a rotary motion. The air piston 2 178 move fore on the outward stroke and aft on the inward stroke compressing the air, the compressed air is pushing and pulling the flywheel vane 244 in a rotary motion. Using compressed air movement to push and pull the flywheel vane 244, attached to the flywheel 240 in a rotary motion. The flywheel 240, attached to the drive shaft 246, rotating the drive shaft 246.

摘要： Apparatus for generating hot combustion gases and steam including a piston block with a piston reciprocally mounted in a bore therethrough having solenoids and sensors for selectively introducing hydraulic fluid into the bore on the first side of the piston to move the piston. Inlets and sensors for selectively introducing air and fuel into the combustion chamber comprising a portion of the bore and to initiate combustion are also provided. The hydraulic fluid used to move the piston is introduced into the bore in a discharge chamber in the bore on the second side of the piston, vaporized and exhausted into a well through an exhaust valve. The exhaust valve is biased toward the closed position by a pneumatic cylinder which resists the force of combustion. Charging of the combustion chamber and the direction of piston movement are controlled by proximity sensors which sense the position of reciprocating control rods and activate a hydraulic spool valve for switching the flow of hydraulic fluid to move the piston.

摘要： A gas generator in the form of a self-starting two cycle free piston internal combustion engine which generates hot exhaust gases and steam as required by the load. A reciprocating piston assembly comprised of three-coupled pistons compresses air in a combustion cylinder to the point of fuel ignition, pumps scavenging air, and compresses and stores a volume of air for recycling the generator. A novel valve arrangement responsive to gas consumption activates the cycling of the piston assembly.
