DETAILED DESCRIPTION OF THE INVENTION

[0015] A general concept of the invention is to introduce turbulences and vortices based on pattern that reverse and twirl the flow of gas in segments to dissipate energy before flow exiting and released to the atmosphere. This concept will be further explained with references to FIGS. 1A-1C and 2A-2D.

[0016] FIG. 1A According to the invention illustrates a prospective view of an exemplary sound reducing device in accordance with embodiment of the invention. Gas flow inside the sound reducing device is split to at least into two flows as illustrated in the cross sectional view FIG. 1B. The split gas is facilitated by protruding separating channel 130 at point U to further increase the flow inside the channel. The reintegration of the gas flowing in separating channel 130 toward gas flow 120 shall be in reverse manner and that is due to that point V is higher than the exiting point W. This opposing of gas flow 130 to 120 is a mean to produce turbulence. The overall flow 110 exiting out toward lower pressure 500.

[0017] FIG. 1C illustrates a prospective view of an exemplary sound reducing device 100 comprises a plurality of separating channels 130 to induce turbulences to substantially reduce pressure at a certain area and substantially maximize the utilization of sound reducing device.

[0018] FIG. 2A illustrates a prospective view of an another exemplary sound reducing device in accordance with embodiment of the invention. Gas flow inside the sound reducing device is split to at least into two flows as illustrated in the cross sectional view FIG. 2B. The split gas is facilitated by protruding separating channel 230 at point X to further increase the flow inside the channel. The reintegration of gas flowing in separating channel 230 toward gas flow 220 shall be in reverse manner as illustrated in FIG. 2B to induce turbulence as well as in rotational spiral flow to induce vortex, which is another mean to drop the pressure. The rotational twirl flow is due to point Z opening is substantially tangential to the wall of exemplary sound reducing device 200 as illustrated in FIG. 2B. The overall flow 210 exiting out toward lower pressure 500.

[0019] FIG. 2C illustrates a prospective view of an exemplary sound reducing device with the outlet of separating channel 230 very close to the sound reducing device 200 main wall for tangential reintegration of gas relative to the main flow 210 to induce vortex to further drop the pressure. Separating channel 260 has tangential outlet opening similar to separating channel 230 with exception 260 is in opposing tangential direction point L relative to point Z. The opposing vortices will further drop the pressure by converting vortex to turbulence before exiting toward lower pressure exit 500.

[0020] FIG. 2D illustrates a prospective view of an exemplary sound reducing device 200 comprises a plurality of separating channels 230 and 260 to induce turbulences and vortices to substantially reduce pressure at a certain area and substantially maximize the utilization of sound reducing device.

[0021] FIG. 3 illustrates a block diagram of an exemplary motion system 900 in accordance with another embodiment of the invention. The exemplary sound reducing device 600 can be used with gas operated system, such as air operated double diaphragm pump 700. Such a motion system 900 typically comprises an energy source 800 with byproduct of natural gas or other types of gas or compressed air from a compressors. Supplied to such equipment as air operated double diaphragm pump 700, which in turn is coupled through mechanical, chemical, or infused with sound reducing device 600, and released directly to environment 500. To further reduce noise, sound reducing device 600 shall be coupled to sound muffler to further drop sound noise effect before released to surrounding environment.

[0022] In summary, the sound reducing device described herein has the advantages of providing sound reduction without icing, and without substantially choking gas flow out of a pump that would drop the overall efficiency of the system upon releasing compressed gas to the atmosphere. Further, although the exemplary embodiment of the invention has been described with reference to a cylindrical round shape with protruding separating channels, it shall be understood, other shapes and inward separating channels may be used there of, such as a cuboid shape, with internal non protruding channels from the body.

[0023] In the foregoing specification, the invention has been described within reference to specific embodiment thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
