FUEL VAPOR PROCESSING APPARATUS

摘要

A fuel vapor processing apparatus may include a canister and a valve device. The canister may include a canister case and may adsorb fuel vapor and allow desorption of fuel vapor. The valve device may include a valve housing defining a fuel vapor passage therein. A valve may be disposed within the valve housing and may control a flow of fuel vapor through the fuel vapor passage. The valve housing may be directly connected to the canister case, so that the fuel vapor passage communicates within the canister case.

1. A fuel vapor processing apparatus, comprising:
a canister comprising a canister case and configured to adsorb fuel vapor and to allow desorption of fuel vapor; a valve device configured to be connected to a fuel tank and comprising a valve housing having a fuel vapor passage defined therein; and a motor operated valve disposed and supported within the valve housing; wherein the motor operated valve comprises a valve seat and a valve member disposed in the fuel vapor passage, and an electric motor coupled to the valve member and configured to move the valve member to change a position of the valve member relative to the valve seat so that the fuel vapor passage is opened and closed according to a change of the position of the valve member; and wherein the valve housing is integrated with the canister case, so that the fuel vapor passage is in communication within the canister case to allow fuel vapor produced in the fuel tank to flow into the canister via the fuel vapor passage when the valve device is connected to the fuel tank.
