Abstract
The present invention is a muffler for pneumatic tools. The invention includes a hollow nozzle, with the exhaust port being reduced, and some orifices placed at the center thereof. A connector is assembled into the air inlet of the nozzle that allows it to be coupled to a pneumatic tool. A cover is mated externally onto the exhaust port of the nozzle to accommodate an orifice and air vent of the nozzle. Some exhaust holes are provided onto the surface of cover. A noise deadener is installed between the surface of the cover and orifice of nozzle. The air vents are placed at a reduced wall around an orifice of the nozzle, such that some fluid can flow through the unreduced cross-section, thus maintaining proper pressure and reducing the noise level for an improved performance.

- 1. Field of the Invention
- The present invention relates generally to a muffler for pneumatic tools, and more particularly to an innovative muffler which allows air vents to be mounted onto the reducing wall of a nozzle hole thereof.
- 2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
- The muffler in the present invention is commonly installed at the exhaust port of pneumatic tools (e.g. pneumatic handles and pneumatic grinders, etc) to reduce the exhaust noise and maintain air pressure for improved performance.
- The typical structure of
muffler 60 is depicted inFIG. 7 , wherein the area ofair inlet 61 is less thanexhaust port 62, and someauxiliary exhaust holes 63 are placed on the wall ofmuffler 60. However, when such a structure is used in actual applications, the fluid A discharged from the pneumatic tool will flow from thesmaller air inlet 61 to abigger exhaust port 62 via silencing cotton. Therefore, silencing cotton is one of the major factors for speed reduction of the flow field as well as excessive back pressure of the exhaust port of a pneumatic tool. This will impair the pneumatic efficiency (speed) of muffler and performance of the flow field, and also will increase noise in applications. - Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve efficacy.
- To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
- The unique muffler of the present invention has some
air vents 14 reduced aroundorifice 13 ofnozzle 10, as shown inFIG. 4 . Some fluid (W1) is still sprayed fromorifice 13. So, the speed of flow field can be maintained due to the reducing nozzle. With configuration ofair vents 14, the other fluid (W2) may flow through an unreduced cross-section, enabling the user to properly adjust the pressure and to reduce the blocking and back pressure of the flow field. Meanwhile, fluid W2 flowing throughair vent 14 can also be exhausted smoothly due to an accelerating effect generated by fluid W1 flowing throughorifice 13, making it possible to reduce noise levels and improve overall performance. - Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

FIG. 1 shows an assembled perspective view of the present invention. -
FIG. 2 shows an exploded perspective view of the present invention. -
FIG. 3 shows an exploded sectional view of the present invention. -
FIG. 4 shows an assembled sectional view of the present invention. -
FIG. 5 shows another cross-sectional view of another preferred embodiment of the present invention. -
FIG. 6 shows a chart of a test results of the present invention. -
FIG. 7 shows a sectional view of typical muffler structure of the prior art. - The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
-
FIGS. 1 , 2, 3, and 4 are preferred embodiments of the muffler of the present invention. - The present invention includes a
hollow nozzle 10, with theexhaust port 11 being reduced. Someorifices 13 are placed at the center. Theair inlet 12 is placed at the other end of the nozzle, with its cross-section being bigger than theexhaust port 11. Someair vents 14 of a predefined number are placed onto the reduced wall aroundorifice 13. The flow speed of gas flowing throughorifice 13 is faster than that flowing throughair vent 14. - A
connector 20 is assembled into an air inlet ofnozzle 10. Theconnector 20 has acoupling part 21, a screw in the preferred embodiment, that allows coupling into a preset exhaust position of existing pneumatic tools (e.g. pneumatic handle, pneumatic grinder, etc). - A
cover 30 is mated externally ontoexhaust port 11 ofnozzle 10 to accommodateorifice 13 andair vent 14 ofnozzle 10.Exhaust holes 32 of predefined shape and number are provided onto thesurface 31 ofcover 30. - A
noise deadener 40 may be made of silencing cotton. It is installed between thesurface 31 ofcover 30 andorifice 13 ofnozzle 10. - A
porous filtering component 50, such as tubular screen, is placed within theconnector 20 to achieve a noise deadening and filtering effect. -
FIG. 5 depicts another preferred embodiment of muffler of the present invention. The difference is that theconnector 20 b is pre-formed into air inlet ofnozzle 10. - Based upon above-specified structural design, the muffler of the present invention is operated as follows:
- Referring to
FIG. 4 , when the muffler is operated, fluid W1 flows from the pneumatic tool intoconnector 20, and then intonozzle 10 throughinternal filtering component 50. In such a case, some fluid W1 will be guided by the reduced space ofexhaust port 11 and sprayed fromorifice 13, then exhausted throughnoise deadener 40 andexhaust hole 32 ofcover 30. The other fluid W2 will be sprayed fromair vents 14 in an unreduced cross-section, and then exhausted throughnoise deadener 40 andexhaust hole 32 ofcover 30. - The actual test results regarding the muffler of the present invention are contained in a report shown in
FIG. 6 , wherein the pneumatic tool is a sandpaper grinder. This test is performed using #180 sandpaper. Different pneumatic tool samples with the muffler of the present invention are represented by 1, 2, and 3 at the top of the report, while the listed Dynabrade Spirit 59020 and Air VANTAGE 5 3/16 tools are prior art pneumatic tools of other brands. The test results listed in the report contain power (W), speed (rpm), air consumption (L/s) with load, noise level (dBA) and weight (Kg). It is thus understood that the muffler of the present invention could really reduce noise levels (dBA) of the pneumatic tool, but also maintain the power (W) and free speed, thereby improving operational performance in applications.
