Hydraulic Constant Pressure Source

Ideal source of hydraulic energy, characterized by constant pressure


Hydraulic Sources


The Hydraulic Constant Pressure Source block represents an ideal source of hydraulic energy that is powerful enough to maintain the specified pressure differential between its inlet and outlet regardless of the flow rate through the source.

The Pressure parameter specifies the pressure differential across the source


where pP, pT are the gauge pressures at the source ports.

Block connections T and P correspond to the hydraulic inlet and outlet ports, respectively. The block positive direction is from port P to port T.



Specifies the pressure difference between the source inlet and outlet. The default value is 1e6 Pa.


The block has the following ports:


Hydraulic conserving port associated with the source inlet.


Hydraulic conserving port associated with the source outlet.
