Mazda CX-5 Service & Repair Manual: Vacuum Pump [Skyactiv G 2.0]
Purpose, Function

Ensures vacuum required for braking force to compensate for the decrease in intake manifold vacuum applied to the power brake unit caused by the retard intake valve closing.
Construction
-
The vacuum pump is installed to the rear housing.
-
For smooth vane rotation, a single-vane type vacuum pump has been adopted which is equipped with an engine oil lubrication passage.
Operation
