Abstract
PURPOSE: To float a seal ring in a receiving boxy by a pressure fluid by providing the lower concave spherical surface of the receiving box positioned at the low pressure side to the sealed pressure acting on the seal ring having a convex spherical surface with a pressure port.
CONSTITUTION: A force based on atmospheric pressure acts on a seal ring 2 having a convex spherical surface at the atmospheric pressure side A to press the ring against the sealing side B, but the seal ring 2 comes upward because the pressure distribution as shown in the drawing is generated in a pressure port 8 mounted on a receiving box 3 having a concave spherical surface and gaps 9a, 9b between the spherical surfaces. The high-pressure liquid supplied to the pressure port 8 is high- pressure much more than the atmospheric pressure Pa, so that an upward resultant force of the pressure distribution can be greater than a downward pressing force by high atmospheric pressure Pa. The seal ring 2 is developed in terms of follow-up against a solid rotary shaft 1 by floating in the receiving box 3.
