Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Simple one-way valve, comparable to the electrical ideal diode model.
- from flowPort_a to flowPort_b: small pressure drop, linearly dependent on volumeFlow
- from flowPort_b to flowPort_a: small leakage flow, linearly dependent on pressure drop
