PURPOSE:To obtain such an engine as generating power through the process in which vapour is steadily generated by heating a part of the sealed vessel containing a fixed amount of working fluid, while on the other hand cooling the vapour periodically and allowing increase and decrease of the vapour pressure alternately. CONSTITUTION:The cylinder chamber 2 heat-insulated from the outside is directly connected to the pressure chamber 1 of which upper half is always cooled from outside and lower half is always heated, and a piston 3 is set in the chamber 2. Working fluid (liquid phase) 4 is sealed in the pressure chamber 1, and the thermal shutter 5 which is made of heat-insulating material and serves to allow the cooling part of the pressure chamber 1 to be exposed to and shielded from steam is slidably set in the pressure chamber 1. When the thermal shutter 5 is at the highest position during operation, the high-pressure steam heated in the heating part is introduced into the cylinder chamber 2, and the piston 3 is operated up and down. On the contrary, when the thermal shutter 5 lowers, and steam is cooled in the cooling part, the piston 3 lowers, and thus power is generated by the repetition of the similar operation. |
