The power source heat engine uses an enclosed working gas arranged between two temperature ranges and has three heat exchangers (1A-C) each with a single connection via a pipe (4A-C) to a working cylinder (2). Each heat exchanger is connected by a valve (5...

A Stirling engine, wherein when a linear motor reciprocatingly move a piston in a cylinder, a displacer also reciprocatingly moves in the cylinder storing the displacer. By this, working mixture moves between a compression space and an expansion space. Tho...

Through stroke control whereby the stroke of a piston 1 is detected and controlled to be equal to a target stroke, the piston 1 is prevented from colliding with a displacer 2, and the refrigerating performance of a Stirling refrigerator 40 is enhanced. Dif...

The two-stroke hot gas motor has a double outer piston (2) with an axial movement in the cylinder body (1). A double inner piston (3) moves axially within the outer piston. The cylinder has two outer limit walls, and a center dividing wall to give two equa...

A Stirling engine comprising a casing (2), a displacer (4) arranged in the casing (2) so as to slide, an expansion chamber (71) and an operation chamber (81) into which, and from which, an operation gas flows with the operation of the displacer (4), and a ...

The invention provides a heating device for an external combustion engine, which is capable of improving stabilization of combustion in a control state with a relatively small quantity of heat and the property of an exhaust gas, and realizing long-time ope...

A passive oscillation-damper (15) is connected to the unit (10) liable to oscillate and is formed of a spring-weight system (17,16) oscillating in counter-phase with the unit. A drive mechanism (18)acts upon the weight of the oscillation damper in the osci...

Energy converter systems as based on free-piston Stirling engine for conversion of supplied thermal energy into a linear movement for supplying directly to a linear generator for conversion into electrical energy, suffer from the relatively high costs and ...

The invention relates to an energy converter (1) comprising a free-piston Stirling engine (2) and a linear generator (3) that is directly coupled thereto and comprises at least two coils (11, 12, 13, 14). The voltage is induced in said coils. A circuit dev...
