Rotary compressors use a rotating vane to compress air from an intake valve. As the rotating vane turns, gas is drawn into the cylinder through a one-way valve (Figure 3-16). The rotor turns, which causes the gas to be compressed as the oval-shaped cylinder becomes smaller. The compressed gas is then forced out of the compressor through another one-way outflow valve. Low-pressure rotary compressors are used in ventilators such as the Bennett MA-1. Piston compressors use the action of a motor-driven piston to compress atmospheric air. The piston is seated within a cylinder casing and is sealed to it with a carbon or Teflon ring. Figure 3-14 illustrates the operational principle of a typical piston air compressor used to power a mechanical ventilator.
