Shaft seal device

摘要

A shaft sealing device using seal rings having a hook shaped portion defining an inner radial lip to engage and seal the shaft. The rings are positioned symmetrically with respect to a spacer to define a sealing liquid chamber between the shaft, the spacer and the lip portion. The spacer has liquid seal passages formed therein to introduce sealing liquid. The axial length of the lip portion is shorter than the axial hight of outer peripheral surface of the seal ring and the inner peripheral surface is tapered inwardly with respect to the axis of the shaft.
