<p>A mechanical seal (11) used to provide a fluid seal between a rotary member (19) such as a drive shaft and a stationary member (21) through which the rotary member passes. The mechanical seal (11) has a rotary portion (25) adapted to be mounted on the rotary member (19) for rotation therewith, and a stationary portion (23) adapted to be mounted on the stationary member. The stationary portion (23) includes a stationary sealing ring (43) having a sealing face (47). The rotary portion includes a housing (57) having a circular recess (61) therein concentric with the axis of rotation of the rotary member. A rotary sealing ring (61) is located in the circular recess (61) and is supported elastically therein and fixed against rotation relative to the housing (57). The rotary sealing ring (61) has a sealing face (65) which sealing contacts the sealing face (47) of the stationary sealing ring (43). The rotary sealing ring (61) is preferably supported in the circular recess by means of an elastic mount (64). A combination of a rotary sealing ring and an elastic mount therefor is also described and claimed.</p> |
