Embodiment Construction

[0188]Reference is now made to FIG. 1, which is a cross-sectional view of one embodiment of the reaction drive system of the present invention. A cylindrical fluid-filled cavity 2 is delimited by a housing 4 and a circular diaphragm 6 . The periphery of the diaphragm 6 is held between an O-ring 8 and an O-ring 10 which are clamped within the housing 4 by a threaded clamping ring 11 . A stand off 12 is rigidly connected to the center of the diaphragm 6 and the other end of the stand off 12 is rigidly connected to the center of a bender-actuator disk 14 . These component connections may utilize bonding, soldering, or other types of low profile joining processes. In most embodiments of the invention, the flex disk 14 does not have any other mechanical connection other than to the spacer block 12, so that its perimeter is free of any mechanical constraints. However, in other embodiments, there may be a mechanical connection as long as the connection does not substantially interf...

Abstract

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.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 60 / 638,195, filed December 23, 2004, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to apparatus and methods for transferring energy to a volume of fluid, and more particularly to the field of linear pumps, linear compressors and other fluidic devices. Background technique [0004] To transfer energy to a fluid within a defined chamber, methods have been employed in the prior art including positive displacement, eg by mechanical agitation or agitation using traveling or standing waves, application of centrifugal force and addition of thermal energy. The transfer of mechanical energy to fluids by means of these methods has a wide range of applications including, for example, compression, pumping, mixing, spraying, synthetic jetting, fluid metering, sampling, air testing of biological weapons...
