Check Valve 2
Check valve with continuous variable
The Check Valve 2 (or Check Valve II) component allows fluid flow in one direction, from port A to port B.
This model uses a continuous-variable to model the change from open to closed. In the open-state the valve has a resistance given by Ropen. In the closed-state the valve has a conductance given by Gclose.
The boolean parameters Use volume A and Use volume B, when true, add optional volumes VA and VB to ports A and B, respectively. See Port Volumes for details.
If two orifices or valves are connected, enabling a volume at the common port reduces the stiffness of the system and improves the solvability.
