Claim Text:
1. A vapor processing system comprising: a vapor source for producing a vapor; an outlet conduit connected to the vapor source for carrying the vapor from the vapor source, wherein downstream of the vapor source the outlet conduit separates into a vapor bypass conduit and a vapor feed conduit; a first vapor control valve disposed in the vapor bypass conduit; a first vacuum chamber connected to the vapor bypass conduit, and disposed downstream of the first vapor control valve; a second vacuum chamber connected to the vapor feed conduit; a controller operatively coupled to the first vapor control valve, wherein the controller is configured to control, via the first vapor control valve, the flow of vapor to the first vacuum chamber; and a pressure sensor operatively coupled to the controller and positioned to sense a pressure in the outlet conduit or the vapor feed conduit, wherein the controller is further configured to vary the position of the first vapor control valve based at least in part on pressure sensed by the pressure sensor so as to control the flow of vapor to the first vacuum chamber and the flow of vapor to the second vacuum chamber.
