Hydraulic Constant Pressure Source

(To be removed) Ideal source of hydraulic energy, characterized by constant pressure

The Hydraulic library will be removed in a future release. Use the Isothermal Liquid library instead. (since R2020a)

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 p_P, p_T 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.

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.

Extended Capabilities

C/C++ Code Generation
Generate C and C++ code using Simulink® Coder™.

Version History

Introduced in R2011a

R2023a: To be removed

The Hydraulic library will be removed in a future release. Use the Isothermal Liquid library instead. Blocks in the Isothermal Liquid library provide increased accuracy, usability, and numerical performance.
