Hydraulic Pressure Source

Ideal source of hydraulic energy, characterized by pressure


Hydraulic Sources


The Hydraulic Pressure Source block represents an ideal source of hydraulic energy that is powerful enough to maintain specified pressure at its outlet regardless of the flow rate consumed by the system. Block connections T and P correspond to the hydraulic inlet and outlet ports, respectively, and connection S represents a control signal port. The pressure differential across the source

where pP, pT are the gauge pressures at the source ports, is directly proportional to the signal at the control port S. The entire variety of Simulink® signal sources can be used to generate desired pressure variation profile.

The block positive direction is from port P to port T. This means that the flow rate is positive if it flows from P to T. The power generated by the source is negative if the source delivers energy to port P.

Dialog Box and Parameters

The block has no parameters.


The block has the following ports:


Hydraulic conserving port associated with the source inlet.


Hydraulic conserving port associated with the source outlet.


Control signal port.
