PURPOSE: To make working gas possible to secure isothermal expansion-isovolumetric cooling-isothermal compression-isovolumetric heating, etc., inside a single cylinder as well as to aim at the compact construction of an engine, by composing a rotary type Stirling engine so as to install a pair of rotors rotating while meeting and parting with each other inside a completely round type cylinder.
CONSTITUTION: A pair of rotors 2X and 2Y rotating while meeting and parting with each other along a cylinder's inner wall through a link mechanism L are housed inside a completely round type cylinder 1. The link mechanism L consists of each of paired guide rods 3X and 3Y, operating rods 4X and 4Y and connecting rods 5X and 5Y. And, a heater 11 such as burner or the like is installed in the outside of the cylinder 1 at expansion areas A-B where the volume of a working chamber lying between these rotors 2X and 2Y grows large by degrees, while a cooler 12 whose condenser tube is embedded is installed to the outside of the cylinder 1 at compression areas C-D. In addition, a heating end 14 is installed to the outside of the cylinder 1 at cooling areas B-C while a heat transmitter 13 consisting of heat pipes, etc., where a heat radiation end 15 is set up each in a heat contacting state is installed to the outside of the cylinder 1 at heating areas D-A, respectively.
