Fig Air engine assembly illustrated below

The engine operates through compressed air entering the cylinder via one of the connecting pipes shown as item 15. The other pipe serves to exhaust the cylinder after the power stroke. The cylinder oscillates in an arc and a hole through the cylinder wall lines up with the inlet and exhaust pipes at each 180° of rotation of the flywheel.

The spindles (Parts 4 and 18), grub screw (Part 5) and the pin (Part 11) would not normally be sectioned. A part section is illustrated at the bottom of the connecting rod in order to show its assembly with the crank pin (Part 11). The BS convention is shown for the spring (Part 16). The BS convention is also shown for cross knurling on the nut (Part 17).

Note. If the solutions to examples 3, 4, 5, and 6 had been required to be drawn in third angle projection, then the views would have been arranged as shown in Fig. 18.13.
