Swirling device for stirling cycle engines
 A burner for a stirling cycle engine which includes an air inlet port, an exhaust port and a combustion chamber between the inlet port and the exhaust port, the combustion chamber having an inlet provided with a swirl producing device including a pair of spaced apart, substantially parallel plates respectively formed with central apertures respectively having centers which are substantially aligned with each other, a plurality of spiral guide vanes disposed between the parallel plates. Each of the guide vanes has a curvature in which a tangent line at a point on the guide vane makes with a straight line passing through the point and the center of the central aperture an angle which is substantially constant and between 30.degree. and 80.degree. so that each two adjacent guide vanes define an inlet passage which is gradually decreased in area toward the central aperture. The inlet passage is communicated at an end adjacent to the central apertures with the combustion chamber and at the other end with the inlet port.
