When a constant load is required from a port (constant consumer), the
volume flow controller (8) is actuated to a stable position.
This keeps both the pressure on the top face of the control ram (14) and
the position of the swash plate (17) constant. As long as the position of
the swash plate (17) remains unchanged, the pump delivers a constant
flow.
The following pressures now result on the volume flow controller (8):
the load pressure (signal) + spring force of the compression spring
(margin pressure) (21) on the left side.
Pump pressure on the right side.
The difference in pressure is the differential pressure corresponding to
the spring force of the compression spring (21).
