  • Sealing disc for vacuum closure
    Patent number: 11092244
    Abstract: A sealing disc for vacuum closure suitable for using in reciprocating movement to an open position or a closed position to open or seal a valve port of an all-metal valve is disclosed. A sealing plate of the sealing disc is formed with a first sealing surface. When the sealing disc is in the closed position, the first sealing surface directly abuts against the valve port of the all-metal vacuum valve.

  • Valve device
    Patent number: 11079028
    Abstract: A sleeve member of a movable unit has a first pressure receiving surface and a second pressure receiving surface. The first pressure receiving surface receives a first fluid pressure in an axial direction opposite to a biasing force of a spring, when a valve member closes a seat opening portion. The second pressure receiving surface receives a second fluid pressure in the same axial direction to a direction of the biasing force of the spring, when the valve member closes the seat opening portion. A first surface area and a second surface area are made to be equal to each other. Each of the first and the second surface areas is an area of a projected portion on a virtual plane perpendicular to the axial direction. Each of the projected portions is obtained when each of the first and the second pressure receiving surfaces is projected to the virtual plane.

  • Fluid valve assembly including fluid driven sealing
    Patent number: 11054043
    Abstract: A fluid valve includes a valve body and a plug. The body includes a chamber and ports that communicate with the chamber. The plug rotates within the chamber, and includes a seal disposed in an annular groove provided on the plug surface. An elastic member is disposed in the groove, and biases the seal against an inner surface of the chamber. When the plug is oriented relative to the body so that the groove is aligned with a port, the seal segregates the chamber into a first chamber that borders an outer surface of the seal and a second chamber that borders an inner surface of the seal, and provides a fluid-tight seal between the first chamber and the second chamber. In addition, the seal inner and outer diameters vary based on a fluid pressure difference across the seal.
