A Stirling engine power generation system comprises a first gas fired Stirling engine driving a scroll compressor to provide heat to a second Stirling engine powered generator. The second Stirling engine is partially submersed in a heat transfer medium that is heated by heat transfer fluid compressed by the Stirling scroll compressor and excess heat from gas firing. The invention further comprises a cam drive system with spherical cam followers, and multiple electrical generators.

Method of conversion of heat into fluid power includes pumping of the working liquid into a hydropneumatic accumulator with gas compression, subsequent gas expansion with displacement of the working liquid from the other accumulator as well as supply of heat to the gas by transferring the gas through the hotter heat exchanger and removal of heat from the gas by transferring the gas through another, colder heat exchanger performed so that the average temperature of the gas during expansion is higher than that during compression, wherein the gas is transferred between different accumulators through said heat exchangers.The device for conversion of heat into fluid power includes at least two accumulators, the means for liquid supply and intake as well as the means for heating and cooling containing at least two flow-type gas heat exchangers installed with the possibility of gas transfer through them between gas reservoirs of different accumulators.The efficiency and rate of heat conversion into fluid power are increased. Reliability and high power density are ensured.

A gear pump (1) comprises a pump housing (2), wherein a working chamber (6) is formed in the pump housing (2). A first gearwheel (11) and a second gearwheel (12) are arranged meshing with each other in the working chamber (6). The first gearwheel (11) has a number of first teeth (13) and the second gearwheel (12) has a number of second teeth (14). A first tooth flank (13a, 14a) and a second tooth flank (13b, 14b) are formed on each of the teeth (13, 14). When the gearwheels (11, 12) mesh, the first tooth flanks (13a) of the first teeth (13) are meshed with the first tooth flanks (14a) of the second teeth (14). A coating (15) is arranged on each of the first tooth flanks (13a, 14a). The coating (15) and the first tooth flank (13a, 14a) are positively connected to each other.

A system of captive oxygen fuel reactor to efficiently generate electricity from hydrocarbon fuel utilizes a flow of oxygen and a flow of hydrogen from an electrolysis unit and a flow of carbon monoxide in order to complete a fuel oxidizer reaction within a heat exchanger unit. The fuel oxidizer reaction emits a flow of steam and a flow of carbon dioxide from the heat exchanger unit re-direct them through a steam rotary piston motor unit, a carbon dioxide rotary piston motor unit, a steam carousel motor unit, a carbon dioxide carousel motor unit, and a duel drum motor unit to generate electrical current. The exhaust gases within the system are properly discharged and stored within respective storage containers for the use of the system or other possible requirements.
摘要:
The power output of a free piston Stirling engine mounted in a free casing configuration is controlled by having a spring drivingly linking the displacer to the casing and controllably varying the amplitude of reciprocation of the casing. A variable casing reciprocation restraint is linked to the casing for applying a variable restraining force to the casing. The restraining force is increased for decreasing the displacer amplitude of reciprocation and thereby decreasing the power output from the Stirling engine and the restraining force is decreased for increasing the displacer amplitude of reciprocation and thereby increasing the power output from the Stirling engine.
摘要:
The power output of a free piston Stirling engine is matched to a gas compressor which it drives and its stroke amplitude is made relatively constant as a function of power by connecting a gas spring to the drive linkage from the engine to the compressor. The gas spring is connected to the compressor through a passageway in which a valve is interposed. The valve is linked to the drive linkage so it is opened when the stroke amplitude exceeds a selected limit. This allows compressed gas to enter the spring, increase its spring constant, thus opposing stroke increase and reducing the phase lead of the displacer ahead of the piston to reduce power output and match it to a reduced load power demand.

A heat exchanger and associated method are provided that may eliminate or reduce the need for an external mechanical or electrical power source to drive the fan by utilization, instead, of a Stirling engine. A heat exchanger includes a plurality of coils configured to carry a primary fluid. The heat exchanger also includes a fan including a plurality of fan blades configured to force a secondary fluid across the plurality of coils to facilitate heat transfer between the primary and secondary fluids. The heat exchanger also includes a Stirling engine operably connected to the fan and configured to cause rotation of the fan blades. A corresponding method is also provided.
