Improvements in and relating to Compressed-air Motors Especially Adapted for Driving or Propelling Vehicles

2070. Ainley, H. F., Wood, C., and Fair, W. F. Jan.25. Motor road vehicles, compressed-air engines for. A large number of reservoirs 3 of highly-compressed air are connected through reducing-valves with an expansion chamber 5 which is pivoted at one end 6, 7. A copper pipe 9 leads from the axis of the trunnions to a heating-chamber 13 communicating with the cylinder jacket 8. Carbon blocks are burnt in the cylinder jacket and warm the cylinder and pipe 9, which zig-zags in the chamber 13 and is then coiled round the cylinder 4 before joining the valve-chest. To stop the vehicle, pumps are put into action which charge reservoirs 15 communicating with the expansion-chamber 5.
