    摘要: An apparatus for checking leakage from a fuel vapor processing apparatus includes an interrupting device capable of interrupting communication between a canister and a fuel tank when a pressure within the canister is negative and a pressure within the fuel tank is positive. A first pressure detecting device can detect the pressure within the canister or its equivalent. A second pressure detecting device can detect the pressure within the fuel tank or its equivalent.

    摘要: A fuel vapor processor has a fuel tank, a canister, a recovery pipe, a fuel pump, a negative pressure generator, a pressure regulator, a fuel intake pipe and a fuel intake regulator. The vapor pipe leads the fuel vapor generated in the fuel tank into the canister for trapping the fuel vapor. The recovery pipe connects the fuel tank and the canister for recovering the fuel vapor trapped in the canister into the fuel tank. The fuel intake pipe directly connects the fuel pump provided in the fuel tank with the negative pressure generator for leading fuel to the negative pressure generator. The negative pressure generator generates negative pressure depending on an amount of fuel supplied to the negative pressure generator from the fuel pump. The fuel vapor trapped in the canister is recovered to the fuel tank through the recovery pipe due to the negative pressure. The pressure regulator is connected with the fuel pump for returning excess fuel discharged from the fuel pump into the fuel tank. The fuel intake regulator disposed on the fuel intake pipe controls the amount of the fuel supplied to the negative pressure generator from the fuel pump.

    摘要: A fuel vapor recovery system has a fuel tank, an adsorbent canister, a separator capable of separating fuel vapor from air, and a negative pressure supplier applying negative pressure to the adsorbent canister in order to remove the fuel vapor from the adsorbent canister. The separator has a housing and a separation membrane. The separation membrane divides an inner space of the housing into a receiving chamber and a permeation chamber and is configured to allow the fuel vapor to pass therethrough. The separator is connected with the fuel tank such that the fuel tank is fluidly connected with the receiving chamber. The negative pressure supplier is fluidly connected with the adsorbent canister via the permeation chamber. When the negative pressure supplier applies negative pressure to the adsorbent canister, purge gas flows from the adsorbent canister into the fuel tank via the permeation chamber.
