Abstract: The present document presents a system and a method for packaging powders in containers (S) through a hopper (T) and a first tube (TC) connected to the hopper (T). Air is sucked both in the area of the first tube and in the area of the hopper. The powder is then drawn directly from inside the hopper thus keeping the flow rate and the degree of compacting of the system constant. Moreover, the powder sucked inside the first tube is thus compacted and can be conveyed compacted towards the outlet. In this way it is possible to control the dosing of the product exiting from the system with high precision.

Abstract: Fuel vapor is prevented from leaking to the outside during refueling, and even when an air space is formed in an upper portion of a fuel filler pipe, a diagnosis of leakage of fuel vapor can be performed with good accuracy. During refueling, fuel vapor is guided from a fuel tank 1 to a canister 3, and is absorbed by the canister 3. A change in the internal pressure of a fuel vapor path including the fuel tank 1, a fuel vapor pipe 4, and the canister 3 is detected by a pressure sensor 8, thereby performing a diagnosis of leakage of fuel vapor. An upper space 16 in the fuel tank 1 and an upper space 17 in a fuel filler pipe 2 communicate with each other through an airflow resistance pipe 12, and in order to restrict flow of fuel vapor from the fuel tank 1 through the airflow resistance pipe 12 into the fuel filler pipe 2 during refueling, the airflow resistance pipe 12 includes an orifice 13.

Abstract: A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow (using a vapor flow sensor) on a nozzle-by-nozzle basis. The disclosed methods and apparatus provide for the determination of A/L ratios for individual nozzles using a reduced number of vapor flow sensors.
