STAGE
The valve head of the first stage forms the top part
of the cylinder. The intake valve is fitted on the top
of the piston. The pressure valve is mounted between
valve head and cylinder.
Note that the valves are operated by the flow of
the air. On the suction stroke, the intake
valves open and the air flows into the cylinders.
At the start of the compression stroke the intake
valve closes and the air opens the pressure valve,
see Fig. 10.
