Hydraulic Pump/Regulator
Introduction
The pump/regulator consists of two variable displacement
type axial piston pumps (P1 and P2) supplying pressurised
oil to operate machine functions, plus a gear type pilot pump
(Pp) to provide pilot circuit pressure for operator control of
machine functions.
Pumps P1 and P2 each incorporate a regulator which
adjusts the output flow rate according to system demand.
