PROBLEM TO BE SOLVED: To provide a device which can suddenly generate high-pressure steam of a desired pressure in a desired timing from superheated liquid, and stably drives an object with excellent reproducibility by means of the high-pressure steam, further, does not require large-scaled equipment such as boiler and steam compressor due to ejection of the high-pressure steam, has a small size, therefore, is portable, has a simple structure, can simply produce high-pressure steam of a predetermined pressure and can perform injection repeatedly.SOLUTION: A high-pressure steam actuator comprises: a pressure-resistant container for charging liquid and tightly closing the liquid; a heating part for heating the liquid in the pressure-resistant container until the liquid gets to a superheated liquid having a temperature higher than the boiling temperature; an opening and closing part for opening the tightly closed state of the superheated liquid produced in the pressure-resistant container at once; and an ejection port which ejects high-pressure steam produced by opening the tightly closed state at once and vaporizing the superheated liquid by means of the opening and closing part. |
