    I'd be thinking that's not possible.

    I think.

    If there is a Black Hole located between the compressor and the discharge service valve

    If the relief valve is passing 100%, then any changes will occur within the compressor body, even though there still maybe compression at the scroll, If you are getting gas movement from the suction side external of the body, you must be getting gas flow through the discharge side external to the body, when running.

    Good point. I like your thinking. Now what if I said digital scroll with unloading ? Same answer right ?

    When a digital scroll unloads, compression itself basically stops (with the relief valve compression still could be occurring), but you still have a pressure difference within the system. So flow will still continue even when unloaded for a short period.

    I do believe on unloading, the upper scroll lifts upward stopping all pumping action.

    Thanks for that file cracker, I don't believe I've worked on a digital scroll before.

    When you say no discharge. Do you mean 0#?

    or discharge is equal to suction?
