Fuel dispensing system with controlled vapor withdrawal |
摘要 |
A system for concurrently transferring a volatile liquid fuel from a source thereof into a fuel tank, while receiving vapors which are displaced from the tank during the inflow of the liquid fuel. Included in the system is a vacuum assist arrangement capable of imposing a vacuum condition on the vapor return line to avoid passage of vapors to the atmosphere. The liquid phase of the system includes a liquid flow regulator adapted to establish a desirable flow rate. Further, a vapor restrictor interposed in the vapor section of the system includes means to both throttle and regulate the vapor flow whereby to establish a favorable vapor:liquid ratio during normal operation.
