Abstract
A sealing assembly includes a first sealing member disposed on a fixed body and a second sealing member disposed on a rotating body while facing the first sealing member, such that when the second sealing member rotates, the first sealing member and the second sealing member work in conjunction with each other to generate flow of fluid in a reverse direction and form a fluid barrier, thereby preventing leakage of the fluid.
