Discharge Position
•
As the piston (1) starts to climb the next cam lobe (2), ports (passages) (3) in the distributor (4) and cylinder block
(5) begin to align with each other, thus starting the discharge cycle. This allows the hydraulic oil (under charge
pressure) to return to the pump as another piston takes over to continue the drive cycle.
