Seal system with cylinder, seal assembly, washer, and shaft
A recently granted patent (Publication Number: US11940049B1) discloses a seal system designed for use in cylinders, comprising a cylinder with a seal assembly located in its bore. The seal assembly includes a seal element, a locking ring, and an energizer. The seal element features a unique spring cavity formed by inside and outside flanges and a center channel section, with a sealing lip projection extending from the inside flange. The system also includes washers and a shaft that project through the seal element, forming an interference fit. Additional features such as recesses, spaced rings, and memory lips enhance the functionality of the seal system.
Furthermore, the patent describes variations of the seal system, including different configurations of washers, additional sealing elements, and the use of grease in the spring cavity. The design allows for effective sealing between components, with the energizer providing the necessary force to maintain the integrity of the seal. The unitary formation of components like the retaining disc and flange section streamlines the manufacturing process, while the inclusion of canted coil springs ensures consistent performance. Overall, the patented seal system offers a comprehensive solution for maintaining a secure and reliable seal in cylinder applications, with various embodiments catering to specific requirements and enhancing overall functionality.
