ABSTRACT:
A gasoline pump includes a cyclone air separator by which air is removed from the gasoline being pumped. The air is vented to the atmosphere through a vent chamber. The cyclone separator includes a scavenging tube for capturing the air bubbles and is coupled to an orifice between the separator and the vent chamber. The scavenging tube and orifice have diameters selected to capture substantially all of the air bubbles and a float valve couples the vent chamber to the pump inlet to return entrained gasoline to the pump. A damped output control valve regulates the internal pump pressure so the cone of air bubbles formed in the cyclone separator remains relatively constant and is efficiently captured by the scavenger tube.
