ABSTRACT:
A leaf spring diffuser for use in an aeration tank of a water treatment system. An amplitude-limiting stop is mounted on each vibrating extremity of the diffuser leaf spring to project into the diffuser air chamber. Each stop engages the diffuser body to prevent the leaf spring from being subjected to an excess bending moment which would otherwise deform the leaf spring and promote clogging of the diffuser parts.
