Abstract

PURPOSE: To reduce the axial length of the mechanical seal and improve the stability of the seal by arranging such that the wire material of a helical spring for urging a seal ring against the sealing end surface has a rectangular sectional profile.
CONSTITUTION: A helical spring 20 having a rectangular sectional profile is urging a seal ring 7 against a seal ring 4 via an urging ring 14 and a flange 9 to increase the contact pressure on the sealing end surface S. Since the spring 20 has a rectangular sectional profile, the axial length can be reduced compared to the construction using a round wire. In addition to the possibility of reducing the axial sealing distance, even when the spring 20 is elongated with wear of the sealing end surface S the urging force is not substantially reduced, so that it is possible to maintain stable sealing performance over a long period of time.
