摘要： A first piston connected to a first shaft and a second piston connected to a second shaft are supported within a housing by using a first leaf-spring unit and a second leaf-spring unit, respectively. Therefore, axial movement of the first shaft or the second shaft can be allowed, while circumferential rotational movement and radial movement can be restricted. The first leaf-spring unit includes two leaf-spring groups that are disposed in a row around the first shaft in the direction of the axis of the first shaft; similarly, the second leaf-spring unit includes two leaf-spring groups that are disposed in a row around the second shaft in the direction of the axis of the second shaft. Therefore, inclinations of the first shaft and the second shaft can be decreased. This results in reduction in contact between the first and second shafts and a cylinder within the housing and friction due to the contact.
摘要翻译：连接到第一轴的第一活塞和连接到第二轴的第二活塞分别通过使用第一板簧单元和第二板簧单元来支撑在壳体内。因此，可以限制第一轴或第二轴的轴向运动，同时可以限制圆周旋转运动和径向运动。第一片弹簧单元包括两个板簧组，其在第一轴的轴线方向上围绕第一轴设置成一列; 类似地，第二板簧单元包括两个板簧组，其在第二轴的轴线方向上围绕第二轴设置成一列。因此，可以减小第一轴和第二轴的倾斜度。这导致第一和第二轴之间的接触减小以及壳体内的气缸和由于接触引起的摩擦。
