Pneumatic Pressure Source

Ideal compressor with constant pressure difference


Pneumatic Sources


The Pneumatic Pressure Source block represents an ideal compressor that maintains a specified pressure difference regardless of the flow rate. Use this block when pressure of an actual device is practically independent of the source flow rate, for example, in factory network outlets or large capacity receivers. The compressor adds no heat. Block connections A and B correspond to the pneumatic inlet and outlet ports, respectively.

A positive pressure difference results in the pressure at port B being higher than the pressure at port A.


Pressure difference

Specify the pressure difference across the source. The default value is 0.


The block has the following ports:


Pneumatic conserving port associated with the source inlet.


Pneumatic conserving port associated with the source outlet.
