Patents by Inventor Christophe Avdjian

Christophe Avdjian has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10094483
    Abstract: The disclosed embodiments include check valves capable of improved dynamic performance (e.g., closing and opening times). The check valves may include an annular disc having an opening. The annular disc may be lightweight and present a reduced surface area to the flow, thus increasing the closure speed of the check valve as well as the opening speed of the check valve. Other components, such as a spacer component, may be reconfigured to modify the check valve for increased performance in a variety of applications, including low flow volume, medium flow volume, and high flow volume applications.

  • Patent number: 9958078
    Abstract: A valve including a flow control assembly having an adaptive, floating closure member is provided. In one embodiment, a ball valve includes a floating closure member having a shoulder enclosed within a recess of the valve body. The recess is larger than the shoulder of the closure member and allows axial movement of the closure member with respect to the valve body and along a flow path through the valve. Additional valve systems, devices, and methods are also disclosed.

  • Patent number: 9915359
    Abstract: A valve including a double piston effect seat assembly with unidirectional lip seals is provided. In one embodiment, a valve includes a ball disposed in a cavity of a hollow valve body. The ball includes a flow port and is rotatable to control flow through the valve. The valve also includes a seat assembly having a seat in contact with the ball, a ring positioned on an opposite side of the seat from the ball, and unidirectional lip seals. The seat assembly is a double piston seat assembly, with the double piston effect provided by the arrangement of the seat, the ring, and the unidirectional lip seals. Additional valve systems, devices, and methods are also disclosed.

  • Patent number: 8985136
    Abstract: A component with sealing grooves for receiving facial seals and with protective arrangements to protect such seals is provided. In one embodiment, the component is a ball valve including a flow control assembly with two closure members having outer surfaces with sealing grooves and protective ridges. The protective ridges facilitate separation of the two closure members from two connectors of a fluid conduit during installation of the body between the two connectors. Additional systems, devices, and methods are also disclosed.

  • Patent number: 8794253
    Abstract: A valve having a flow control assembly with a bore having particle-deflecting features is provided. In one embodiment, the bore of a flow control assembly of a valve includes a contour shaped to deflect particles in a fluid stream through the valve toward the center of the fluid stream and away from a sealing surface of the flow control assembly. The bore may also, in some embodiments, create a Venturi effect that cleans sealing surfaces by drawing particles away from the sealing surfaces. Additional valve systems, devices, and methods are also disclosed.
