Negative flow control
By changing the pilot pressure Pi, the
pump tilting angle (delivery flow) is
regulated arbitrarily, as shown in the
figure.
This regulator is of the negative flow
control in which the delivery flow Q
decreases as the pilot pressure Pi rises.
With this mechanism, when the pilot
pressure corresponding to the flow
required for the work is commanded, the
pump discharges the required flow only,
and so it does not consume the power
uselessly.
REGULATOR
Regulator consists of the negative flow control, total horse power control and power shift control
function.
