DCFirst Claim
1. An apparatus comprising:
- a tank configured to contain air at an elevated pressure;
an air compressor operative to supply compressed air for storage in said tank;
a motor with an output shaft;
a fan mounted on said output shaft;
a drive assembly configured to interconnect said motor operatively with said compressor;
a base structure configured to support said compressor, said motor and said drive assembly on said tank; and
a shroud configured to cover said compressor, said motor, said drive assembly and said base structure on said tank;
said shroud having a cooling air inlet port, a cooling air outlet port, and a plurality of internal wall portions configured to direct cooling air to flow over said motor and said compressor upon flowing through said cover from said inlet port to said outlet port under the influence of said fan;
said shroud further having a lower section configured as a skirt extending around the periphery of said base structure, and further having an upper section configured as a cover which extends over said compressor, said motor and said drive assembly when said upper section is received over said lower section in an installed position;
said lower section of said shroud being fixed to said base structure by a plurality of fasteners that are spaced apart about said periphery of said base structure, and said upper section of said shroud being configured to be fastened to said lower section by a solitary fastener accessible from above said upper section.

Abstract
An apparatus comprises a tank, an air compressor, and a motor with an output shaft. A fan is mounted on the output shaft. A drive assembly interconnects the motor operatively with the compressor. The apparatus further includes a base structure and a shroud. The base structure is configured to support the compressor, the motor and the drive assembly on the tank. The shroud is configured to cover the compressor, the motor, the drive assembly and the base structure on the tank. The shroud has a cooling air inlet port and a cooling air outlet port. A plurality of internal wall portions of the shroud are configured to direct cooling air to flow over the motor and the compressor upon flowing through the cover from the inlet port to the outlet port under the influence of the fan.
