摘要

The axial pneumatic motor has a piston working in a cylinder and connected to one or two parts. A distribution pipe passes through part of the piston and transfers air between opposite sides of the latter via passages extending upwards in the cylinder head. On the opposite side of the piston the air is discharged to atmosphere under the control of the governor, passing through the cylinder head and the discharge passage.
