| 31. | The inlet valve is wide open.
|
| 32. | The inlet valves are pulled open with an eccentric-driven trips, the rapid closure is damped using a dashpot.
|
| 33. | The inlet valve allows flow from the inlet line to the piston chamber, but not in the reverse direction.
|
| 34. | After all the water is out, close the drain valve and open the inlet valve coming from the boiler.
|
| 35. | Next, install the inlet valves.
|
| 36. | The squirts of fuel are very exact positioned ( two jets on the backside on each inlet valve ).
|
| 37. | As before the engine is arranged to have interchangeable exhaust and inlet valves on opposing sides of the engine.
|
| 38. | At the end of each line is an inlet valve with a spring-loaded closure gate and a power switch.
|
| 39. | The opening inlet valve can then at typical compression ratios fill 10 % of the cylinder before beginning downward travel.
|
| 40. | Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.
