A fluid energy transfer device, including a chamber for receiving a fluid, at least a portion of the chamber comprising a movable portion relative to another portion of the chamber, the movable portion being adapted to change the volume of the chamber from a first volume to a second volume by movement of the movable portion. The device further includes a bender actuator attached to the movable portion, wherein the bender actuator is at least one of (i) connected directly to the movable portion and (ii) linked to the movable portion, to form a bender-movable portion assembly, wherein the bender is effectively not connected and effectively not linked to any other component of the device other than the movable portion, and wherein the bender-movable portion assembly is adapted to move substantially only due to oscillation of the bender at a drive frequency.
