バ。[Scope of Claim for Utility Model Registration] (1) In a variable pressure reservoir for controlling the internal pressure of a two-phase fluid loop, a cylindrical reservoir body with both ends closed has a force that is slidable in the axial direction of the reservoir body. A pressure plate is provided to form a fluid chamber and a pressurized chamber,
The fluid chamber and the two-phase fluid loop are communicated with each other, and one of an electromagnet and a permanent magnet is provided at an end on the pressurizing chamber side, and the other is provided on the pressurizing plate so that they can face each other. variable pressure reservoir. (2) In a variable pressure reservoir that controls the internal pressure of a two-phase fluid loop, a pressure plate that is slidable in the axial direction of the reservoir body is provided in the tubular reservoir body with both ends closed, and the fluid chamber and forming a pressure chamber, and communicating the fluid chamber with a two-phase fluid loop;
A variable pressure reservoir characterized in that an end on a pressurizing chamber side and a pressurizing plate are connected via a shape memory alloy spring.
