Constant pressure flow source in SimHydraulics

I've built an hydraulic circuit for one aircraft components. However, we're not able to locate a proper input block which can provide constant pressure flow, while flow changes with load.

You have two options with hydraulics models: constant pressure and constant flow. These blocks can be found under Simscape > Foundation Library > Hydraulic > Hydraulic Sources. This library also has flow rate and pressure sources that can be externally controlled with Simulink signals.

If you use constant pressure, the flow rate will depend on the load of your hydraulic system.

If you use constant flow rate, this source will provide whatever pressure is necessary to maintain that flow rate through it.

Hi Sebastian What can be done if I wish to implement a load curve of the pump, which can neither be represented by constant pressure or constant volume?
