Abstract
A Stirling engine is provided in which the burner has an annular shape and is disposed in an outside lower portion of the heater. The burner has a plurality of fuel delivery holes and a plurality of air supplying holes which open through an inner circumferential surface of the burner. The arrangement permits the Stirling engine to use a fuel line under a low pressure and to be easily used as a power source of a compressor for an air-conditioning and heating device for domestic use. Also, the arrangement permits the Stirling engine to be constructed without a fuel/air mixing device and to be used with a smaller blower. Furthermore, the arrangement permits the burner to be made from a variety of material, thereby reducing the manufacturing cost.
Claims8
A Stirling engine, comprising:
- an expansion chamber defined in an expansion cylinder by an expansion piston;
- a compression chamber defined in a compression cylinder by a compression piston and communicating with the expansion chamber via a heater, a regenerator, and a cooler;
- a combustion chamber in proximity to said expansion and compression cylinders;
- a burner located within said combustion chamber, said burner having a substantially annular shape defining an inner circumferential surface and at least one outer surface;
- said heater being circularly disposed in the center of said combustion chamber and radially interiorly of said inner circumferential surface of said burner;
- an air supply means delivering air to said burner;
- a fuel supply means delivering fuel to said burner;
- said burner including a plurality of fuel delivery holes receiving fuel from said fuel supply means, and a plurality of air supply holes receiving air from said air supply means,
- at least one of said pluralities of holes extending from said inner circumferential surface of said burner to an outer surface of said burner.
