Air compressor apparatus including noise-reducing means

A noise-reducing enclosure for packaging air compressors and similar devices which comprises:

• a front wall, a rear wall, two opposite side walls and a bottom surface defining an interior open region;
• a top lid member of suitable size and construction to close the top of said interior open region;
• two interior baffle plates joined to said bottom surface and arranged so as to divide the entire interior open region into only three chambers, including an air inlet chamber at one end, an air outlet chamber at the opposite end and an air compressor chamber therebetween, said air inlet chamber being in flow communication with an inlet aperture open to the atmosphere and disposed in said bottom surface and having a flow exit adjacent said top lid member, said air outlet chamber having a flow entrance adjacent said top lid member and is in flow communication with an exit aperture open to the atmosphere and disposed in said bottom surface, said flow exit and said flow entrance defining an air flow path across the top portion of said air compressor chamber;
• and
• air circulation means disposed in said air flow path adjacent said flow entrance and above the corresponding baffle plate for drawing air from said air inlet chamber and through said air compressor chamber.

An air compressor apparatus including noise-reducing means for converting ambient air into compressed air, said air compressor apparatus comprising:

• an air compressor having an inlet for ambient air and an outlet for compressed air;
• and
• a noise-reducing enclosure surrounding said air compressor and comprising:
• an air compressor chamber wherein said air compressor is positioned, said air compressor chamber having a lower portion for receipt of said air compressor and an upper open portion thereabove;
• an air inlet chamber located adjacent one end of said air compressor chamber and having an inlet aperture open to the atmosphere at its lowermost end and a first flow communication aperture adjacent its uppermost end for flow communication with the interior of said air compressor chamber;
• an air outlet chamber located adjacent the other opposite end of said air compressor chamber and having an outlet aperture open to the atmosphere at its lowermost end and a second flow communication aperture adjacent its uppermost end for flow communication with the interior of said air compressor chamber, said first and second flow communication apertures in said uppermost ends creating a direct air flow path from inlet aperture to outlet aperture which passes through said upper open portion of said air compressor chamber above said air compressor;
• and
• fan means disposed in said direct air flow path between said air compressor chamber and said air outlet chamber for drawing air out of said air compressor chamber.
