Claims

[Claims for Utility Model Registration] (1) First and second bodies separably coupled to each other so as to constitute a valve body chamber by a recess formed in at least one opposing surface; a plate-shaped electrostrictive element having at least one end sandwiched between the main body and the second main body and positioned within the valve body chamber; an inlet flow path and an exhaust flow path that penetrate the first and second bodies and are opened by forming valve seats at positions corresponding to the valve body; and the first or second main body. A valve using an electrostrictive element, characterized in that the valve includes an outlet flow path that penetrates the main body of the valve body and opens into the valve body chamber. (2) A utility model according to claim 1, characterized in that a plurality of the valve bodies are fixed to one end of the electrostrictive element, and the other end is held between the first and second bodies. A valve using an electrostrictive element. (3) Utility model registration claim 1, characterized in that a plurality of the valve bodies are fixed to substantially the center of the electrostrictive element, and both ends are sandwiched between the first and second bodies. A valve using the electrostrictive element described in . (4) A coil spring is provided between the electrostrictive element and a peripheral portion of the exhaust flow path to bias the valve body fixed to the electrostrictive element in a direction to bring the valve body fixed to the electrostrictive element into close contact with the valve seat of the inlet flow path. A valve using an electrostrictive element according to claim 1 of the utility model registration claim, characterized in that: (5) The electric device according to claim 1 of the utility model registration, characterized in that a magnet for attracting the electrostrictive element to the side of the exhaust flow path is disposed around the exhaust flow path. A valve using a strain element.
