3. Positive Displacement
Classification
Positive Displacement
Rotary
Single Rotor
Vane

4. How It Works Rotor with multiple slides or “vanes”
Rotation creates centrifugal force, forcing vanes out
Eccentricity results in unbalanced load
Unbalanced load responsible for change in volume
Volume decreases, increasing pressure
Increased pressure forces oil out
