Seal with floating insert decoupling radial biasing forces
A recently granted patent (Publication Number: US12000486B2) discloses a unique seal design comprising an annular jacket with a body featuring a first lip and a second lip defining an annular recess. Within this recess, a circumferential spring is positioned adjacent to one of the lips, along with a floating circumferential insert. This design allows for the decoupling of radial biasing forces on the first and second lips, ensuring effective sealing. Additionally, a void is present between the floating circumferential insert and a second circumferential insert within the annular recess, enhancing the functionality of the seal.
Furthermore, the patent describes a seal assembly involving this innovative seal design, positioned between two members. The assembly includes the annular jacket with the unique lip configuration, the circumferential spring, and the floating circumferential insert. Notably, the radial biasing forces on the first and second lips are decoupled, providing efficient sealing capabilities. The presence of a void between the floating circumferential insert and a second circumferential insert within the annular recess further enhances the performance of the seal assembly. This patented technology offers a novel approach to sealing mechanisms, ensuring effective performance and reliability in various applications.
