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...

AI Technical Summary

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 apparatus and method disclosed herein allow users to effectively reduce the noise and vibration of the air storage tank caused by the air entering the tank.

[0011]In an exemplary embodiment of the present invention, an air compressor assembly includes an air compressor and an air storage tank suitable for storing pressurized air and having an intake port in an upper surface of the air storage tank. A noise reduction member is disposed between the compressor and the air storage tank and is capable of reducing noise generated by the delivery of pressurized air from the compressor to the air storage tank. The noise reduction member captures the high velocity bursts of pressurized air and discharges the air at a slower velocity and thereby more continuous flow.

[0012]Advantages include at least the following: less vibration of the tank caused by the pulses of air coming out of the compressor, resulting in less noise. The pulsing of air is caused by the stop-and-go push of air from the compressor. Reducing air storage tank vibration and noise, makes the operation of the compressor more comfortable and a more positive experience for the user. In addition, environmental noise produced by the air tank is reduced.

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.

Specifically, air storage tanks receiving pressurized air from a compressor generate significant vibrations.

The shockwaves in turn, generate noise outside of the tank.

This noise includes ringing and rattling caused by the bursts of high velocity air as the air passes from the compressor through the connecting tube and hits the inner walls of the storage tank.
