Benefits of technology

[0010]This application relates to an apparatus and method for reducing the noise of a compressed fluid, such as air entering a storage tank. The appar

Problems solved by technology

However, check valves can suffer from corrosion due to contact with the condensate.
One long unresolved problem with such air compressor assemblies is that they tend to generate significant noise when compressed air is discharged from the compressor to the air storage tank.
Vibrations and noise make the operation of the compressor less comfortable.

second embodiment

[0038]In the present invention, shown in FIG. 3, the muffler 40 can be welded directly to the air storage tank 14. The muffler 40 includes a tubular body 42 having an inlet 44 at a first end and an outlet 46 at a second end opposing the first end. The inlet 44 has a greater diameter than the outlet 46. The muffler 40 is integrally connected to the air storage tank 14. For example, as shown in FIG. 3, the tubular body 42 is welded with weld bead 56 at the intake port 18 on an inner wall of the air storage tank 14. The outlet 46 of muffler 40 restricts the flow of air being delivered from the compressor 12 to the air storage tank 14.

[0039]Alternatively, the upper outer surface of the muffler can be a threaded surface that is threaded onto an inner threaded surface of the weld flange. Also, the upper inner surface of the muffler can be a threaded surface that is threaded onto an outer threaded surface of the weld flange 34.

[0040]As shown in FIG. 3, the outlet 46 in the second end of th...

fourth embodiment

[0047]In FIG. 9, the muffler 920 serves as the air discharge tube for pressurized air being delivered from the compressor 912 to the air storage tank 914. The muffler cavity 923 extends from the compressor to the check valve 930 serving as the restricting member. Pressurized air is discharged from the muffler / check valve combination through the outlet 926 and enters the air storage tank 914.

[0048]More than one muffler of the present invention can be used in series along the path between the compressor and the air storage tank.

[0049]The muffler can also protect the check valve from corrosion caused by condensate in the air storage tank. Tilting of the compressor, for example, during movement from one location to another location, could allow water or other condensate to enter into air compressor. The check valve serves to check the flow of fluid from the air storage tank to the compressor. However, if the check valve comes in contact with water or other liquid condensate, over time, ...

Abstract

A noise reduction device including a tubular body having an open first end, a second end opposite the first end, and a cavity located between the first end and the second end. The second end of the tubular body being disposed opposite the first end. The second end has at least one opening with a diameter smaller than the diameter of the opening in the first end.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority under 35 U.S.C. §119 to the U.S. Provisional Application Ser. No. 61 / 350,226 filed on Jun. 1, 2010, which is herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates in general to the field of air compressors and particularly to an apparatus and method for reducing the noise of compressed air entering into an air storage tank in a compressor assembly.[0004]2. Description of the Related Art[0005]A compressor assembly normally provides a source of compressible fluid which is temporarily stored in a pressurized fluid tank. Typically, an electric motor or a combustion engine is connected to a compressor unit to activate the compressor. The compressor unit typically includes a piston assembly, or compressor pump, which compresses the fluid and forces it into the fluid pressure tank for temporary storage.[0006]Likewise, a...
