Regenerative pneumatic propulsion apparatus

A pneumatically powered vehicle structured with a chassis having fixed thereto a regenerative pneumatic propulsion system for rotating at least one drive wheel of the vehicle, the propulsion system of the vehicle comprising:

• at least one pneumatic powered motor fixed to an end of an axle assembly of the propulsion system;
• the axle assembly structure having an elongated and hollow configuration, with an outer wall structure establishing an interior volume, the axle assembly further arranged with a rotatable tubular drive member having portions thereof disposed within the outer wall structure and operatively coupled for rotating by the pneumatic powered motor causing a rotating of the tubular drive member and at least one drive wheel of the vehicle coupled thereto for propelling of the vehicle;
• the axle assembly further arranged with a plurality of filtered air intake ports to enable filtered ambient air to enter the interior volume of the axle assembly;
• a plurality of radial compressor units mounted to the axle assembly and disposed about and operatively coupled to the tubular drive member of the axle assembly so that as the tubular drive member rotates, each compressor unit may be enabled causing a drawing of filtered air from the interior volume of the axle assembly and a producing of pressurized air at an air outlet port of the radial compressor unit;
• at least one pneumatic reservoir tank structured to accept the pressurized air from the air outlet ports of radial compressor units, so as to increase a volume of pressurized air available in the reservoir tank;
• at least one pneumatic valve placed in-line with a coupling between the reservoir tank and the pneumatic powered motors, which is controllable for delivering to each pneumatic powered motor a selected and adjustable flow of pressurized air from a reservoir tank, thereby enabling a controlled propelling of the vehicle.
