SYSTEM FOR RECOVERING FLUID VAPOR FROM AN OIL TANK OF AN OIL CAR AND AN OIL STORAGE TANK OF A GASOLINE STATION

摘要

PURPOSE: A fluid vapor recovery system of an oil car is provided to prevent loss of fuel and environmental pollution by recovering fluid vapor from an oil tank of the oil car as well as an oil storage tank of a gasoline station in supplying fuel from the oil car to the gasoline station or vice versa. CONSTITUTION: A vent hole(25) of an oil storage tank(21) is connected to a vent hole(33) of an oil car tank(31) by a connecting hose(35) in feeding fuel from the oil storage tank to the oil car tank through a fuel supply hose(23), and fluid vapor is discharged from the oil car tank through the connecting hose to the oil storage tank by increasing internal pressure of the oil car tank. The vent hole of the oil car tank is connected to a vent hole(45) of a gasoline station oil reservoir tank(41) by a connecting hose(47) in supplying fuel from the oil car tank to the gasoline station oil reservoir tank, and fluid vapor is supplied from the gasoline station oil reservoir tank to the oil car tank by increasing pressure of the gasoline station oil reservoir tank.
