# Hydraulic Constant Pressure Source

Ideal source of hydraulic energy, characterized by constant pressure

Hydraulic Sources

## Description

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

$p={p}_{P}-{p}_{T}$

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.

## Dialog Box and Parameters

Pressure

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

## Ports

The block has the following ports:

`T`

Hydraulic conserving port associated with the source inlet.

`P`

Hydraulic conserving port associated with the source outlet.
