Change the minimum displacement of a variable-displacement pressured-compensated pump

Hello,
I am using a variable-displacement pressured-compensated pump in my hydraulic system. The MathWorks Help says: The displacement can be changed from its maximum value down to zero. Is there a way to change the minimum displacement from zero to another value smaller than its maximum displacement? For expample: The datasheet provides a p-Q-Diagram of a variable-displacement pressured-compensated pump with a maximium displacement of 35 L/min at minimum pressure and a minimum displacement of 5 L/min at maximum pressure.
Thank you very much for your help
Best regards,
Sebastian

Hi Sebastian,
This is a limitation of the Variable-Displacement Pressure-Compensated Pump in the Hydrualic domain. The Pressure-Compensated Pump (IL) in the Isothermal Liquid library has an option to set a nonzero Minimum displacement. You can interface the Isothermal Liquid block with the Hydraulic domain network using an Interface (H-IL) block, or upgrade the entire model to the new Isothermal Liquid domain using the hydraulicToIsothermalLiquid function.
Regards,
Jocie
