That device (which could be more accurately termed a solenoid
valve) is the means via which the ECU controls the manifold vacuum that gets applied to the lower port of the bypass-valve actuator (which is itself often called a bypass valve).
The upper port of said actuator also receives vacuum from the neck of the supercharger. Which should, btw, be a pretty clear indication right there that the operation of said actuator is anything but a straight-line (i.e., linear) affair.
So, is it some kind of trivial pursuit to seek information regarding the bypass valve and the logic behind when/if it gets opened or closed? Maybe, except am believing it plays a major role in determining boost pressures, and boost pressure is, after all, a matter of such significant interest that it has its own, prominently positioned gauge.

Greetings The ByPass valve contains the entry point and exit point of air (pressure), Which one is going to where ? To test the sealing and correctness of the bypass valve, I connected the bottom line in a low pressure of 4psi (0.3 bar) And he opened the leg completely, How can I fix the...

Am still wondering, though, why the pictured device has three ports. Am also wondering why the bracket that attaches said actuator to the supercharger body has slotted holes ...
