Bladder surge suppressor

An attachment assembly for attaching an elastomeric bladder disposed in a container to the container and fixing rotational movement of the elastomeric bladder, wherein the container includes an opening and the attachment assembly comprises:

• a first attachment member having a unitary one-piece construction with a central opening configured to accommodate placement of a first portion of a valve stem therethrough that extends from the elastomeric bladder, wherein the first attachment member is configured to be disposed within the container against the bladder or valve stem, wherein the first attachment member has an outer diameter section adjacent a top-most surface of the first attachment member that is sized smaller than the container opening, and wherein at least a portion of the first attachment member outer diameter section is configured for placement within the container opening;
• and
• a second attachment member having a unitary one-piece construction with a central opening configured to accommodate placement of a second portion of the valve stem therethrough extending axially from the first attachment member central opening, the second attachment member having a top-most surface with an outside diameter configured for placement outside of the container and having an outer diameter sized greater than an inside diameter of the container opening, the second attachment member having a bottom-most surface configured to connect with the first attachment member only along the first attachment member top-most surface through the container opening;
• wherein one or both of the first attachment member central opening and second attachment member central opening includes a sidewall having a flat surface section configured to register with a flat surface section of the valve stem first portion or second portion to fix rotational movement of the bladder relative to one or both of the first attachment member and second attachment member.

An attachment assembly for use with an elastomeric bladder to attach and contain the elastomeric bladder within a fluid or gas container, the attachment member assembly comprising:

• a first attachment member having a central opening that is sized to accommodate placement of a valve stem of the elastomeric bladder therein, the first attachment member configured to be disposed within the container, and having a planar top-most surface and having a bottom-most surface that is opposite the top-most surface and that is configured to contact at least a portion of the bladder or bladder valve stem, wherein the first attachment member includes a first outside diameter section extending axially a partial distance from the top-most surface to a second outside diameter section that extends axially to the bottom-most surface, wherein the first outside diameter section has an outer diameter that is sized differently than an outer diameter of the second outer diameter section;
• and
• a second attachment member having a central opening that is sized to accommodate placement of a portion of the valve stem extending from the first attachment member therein and having a planar bottom-most surface configured to connect with the first attachment member along only the first attachment member top-most surface, and having a top-most surface that is opposite the bottom-most surface of the second attachment member, wherein the second attachment member includes a first outside diameter section that extends axially a partial distance from the second attachment member top-most surface to a second outside diameter section that extends axially towards the second attachment member bottom-most surface, wherein the second attachment member first outside diameter section has an outer diameter that is sized differently than an outer diameter of the second attachment member second outside diameter section;
• wherein one or both of the first attachment member central opening and second attachment member central opening includes a surface feature that is configured to register and abut with a surface feature of the valve stem to fix rotational movement of the bladder structurally by interplay between the abutting surfaces features relative to one or both of the first attachment member and second attachment member.
