Blade swingCylinderIt is small in size and lightest in weight, but requires high manufacturing precision, difficult to seal, large leakage, and the dynamic seal contact area is large, and the friction of the seal The resistance loss is large and the output efficiency is low, less than 80%. Therefore, its application is limited, and it is generally only used in situations where the installation position is restricted, such as the rotation of fixtures, opening and closing of valves, and table rotation.
