Abstract: A method of operating a vapor recovery system that recovers vapors expelled from a vehicle during refueling at a fuel dispensing point and returns the vapors to an underground storage tank through a vapor flow path that is in fluid communication with an air to liquid regulator valve and a vapor pump. The method includes dispensing fuel into the vehicle through the fuel dispensing point, regulating an amount of vapor that is recovered through the fuel dispensing point with the air to liquid regulator valve in proportion to the fuel dispensed into the vehicle, detecting a parameter of the vapor recovery system, and maintaining a substantially constant pressure level in a first portion of the vapor return path that is disposed between the vapor pump and the air to liquid regulator valve.

Abstract: 599862 A vapour recovery system recovers vapours expelled from a vehicle during refuelling at a fuel dispensing point and returns the vapours to an underground storage tank through a vapour flow path that is in fluid communication with an air to liquid regulator valve and a vapour pump. The air to liquid regulator valve (500) regulates the amount of vapour that is recovered through the fuel dispensing point in proportion to the fuel dispensed into the vehicle, and a controller (270) monitors a parameter of the vapour recovery system such as, for example, the pressure within a first portion of the vapour flow path (220) between the inlet side of the vapour pump (250) and the air to liquid regulator valve, and maintains a substantially constant pressure level in the first portion of the vapour flow path. As the amount of fuel that is dispensed by the fuel nozzle (210) increases, the amount of vapour laden air that is drawn into the combined inlet portion of the vapour return passages by the vapour pump increases. This increased load on the vapour pump causes the vapour pump to begin to slow down as more torque is required but the current supplied to the motor (252) remains constant. In response to the reduction in speed, the control system increases the amount of current provided to the motor, thereby increasing the amount of torque that is produced. As such, the vapour pump is able to maintain the desired vacuum level within the combined inlet portion of the vapour return passages even though the amount of vapour being drawn through the vapour pump has increased. The control system similarly reduces the amount of current that is supplied to the motor when the load on the vapour pump is reduced.
