  • Valve with a level gauge for a liquefied carbon dioxide container
    Patent number: 4580450
    Abstract: The invention relates to a valve with a level gauge for a elongated liquidfied carbon dioxide container, comprising a body, and a level gauge having at least one articulating or flexible part between a float and a rod connected on the float to move an indicating member by a detecting member fixed thereon. The flexible part allows the float to contact the inner periphery of the container, wherein the inner periphery of the container shares a part of the weight of the float, cancelling the bending moment which is produced by the weight of the float and acting on the rod.
