Re: Mulit-postioning with pnuematics this year?
With two incoming constant pressures the volume has little factor. The two pressure will create forces that will either equalize somewhere or the force of one will overcome the other.
The previous system I used Close and opened on the exhaust of the double solenoid such that when it was open the cyclinder would extend or retract but when it closed why extending or retracting the cyclinder would continue to compress until the forces equalized out. It didn't depend on volumes although reducing the volume will create the system to react quicker.
