Does this actually work?

Perhaps I don't understand double solenoid valves.

I thought that the double solenoid valve takes a pulse on one coil to move the valve one way and a pulse on the other coil to move the valve back. Put another way, the valve "stays put" until actively kicked the other way. I think of them as a kind of "latching relay" only for air.

If my understanding is correct, then I don't think what you described above will work. The valve will always be in state A or state B (except for a few milliseconds as it transistions). So, the cylinder will always be driven to one state or the other.

Perhaps what you intend to say was you used 2 single solenoid valves. In this case, you can activate one solenoid or the other and get the behavior you describe.

By the way, if I understand you correctly, when neither solenoid is activated, the cylinder stops putting force on the output shaft. BUT the shaft is not locked. Because the both sides of the cylinder piston are open to the atmosphere.

Am I missing something?

Joe J.

P.S. Would it be legal to get a sort of "squishy" lock condition by using the check valves to keep the air from escaping? Perhaps not if the pressure regulator was not allowed to bleed off any excess pressure generated. Thoughts?
