ABSTRACT:
A vacuum assisted system for loading a liquid product containing vapor into a tank comprising apparatus for loading the liquid product under pressure into the tank, and a system for disposing of vapor recovered from the tank during loading. The system also includes conduit for interconnecting the tank and the vapor disposal, and a blower in the conduit for applying a predetermined vacuum to the tank. The loading apparatus pressure and the blower vacuum act to move vapor from the tank to the vapor disposal. A by-pass conduit is formed about and between the outlet and the inlet sides of the blower, and a valve is provided in the by-pass conduit which is responsive to the vacuum at the inlet side of the blower for progressively opening to permit by-pass flow of vapor from the outlet side to the inlet side of the blower. The valve provides maximum by-pass when the vacuum approaches a predetermined maximum level.
