  • Backup seals in rotary pumps
    Patent number: 10294952
    Abstract: Arrangements for promoting the restriction of fluid flow along a shaft via providing a deformable ring member in an annulus between the shaft and housing. In an initial general condition, the deformable ring member permits free fluid flow in a general direction along the shaft while in a second, constricted condition, the deformable ring closes or blocks a gap or clearance normally conducive to free fluid flow to thereby restrict fluid flow. An actuation medium, which can take any of a very wide variety of forms, preferably promotes constriction of the deformable ring member directly or indirectly.
    Type: Grant
    Filed: February 14, 2014
    Date of Patent: May 21, 2019
    Assignee: CURTISS-WRIGHT ELECTRO-MECHANICAL CORPORATION
