under the condition of low pressure, the U-shaped Y-shaped sealing ring is sealed only by the interference deformation of the lip. Due to the small contact area, the friction force is relatively low. As the pressure increases, the elastic deformation of the lip increases, with the increase of tension, compression and bending stress, the radial pressure of the U-ring automatically increases, and the length of contact with the sealing surface continuously increases until the entire axial length of the U-ring contacts with the sealing surface, thus ensuring good sealing performance under high pressure. U-shaped Y-shaped seal ring is the most commonly used oil seal in hydraulic cylinder, and is a typical lip seal, which can obtain good seal whether used for piston or piston rod.
