  • Sealing structure for sliding parts of powder particle conveying valves
    Patent number: 4155562
    Abstract: A sealing structure including a packing for sealing a sliding part of a valve, such as a rotary or reciprocating valve. The sealing structure is used for connecting together devices having a pressure differential between them and in particular for devices conveying powder particles. The packing of the sealing structure is formed by jointing together a member having a solid lubricating property and a member of substantial mechanical strength.
