AIR MOTOR Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: proposed air motor can be used as power plant for pollution free vehicles. Proposed air motor is made in form of piston expansion machine containing in line cylinder block with head, pistons mechanically connected with output shaft, distributing mechanism with rotary cylindrical spool installed in head bore and communicating cylinder expansion chambers with intake channels made in head and connected to compressed air source, and exhaust pipeline. Blind metering chambers with radial channels made in spool body communicate periodically in turn with intake channels and with intake ports made in head from side of expansion chamber coaxially with intake channels. Discharge ports connected with discharge pipeline are made in cylinder wall in zone of bottom dead center.

EFFECT: improved reliability, simple design.
