摘要： A fuel vapor leak detecting apparatus, includes: a valve which is in a vapor purge system including a canister that is communicated with a fuel tank and an internal combustion engine, and which controllably closes the vapor purge system; a pressurizing section which introduces atmospheric air into the vapor purge system to pressurize the vapor purge system; and an internal-pressure measuring section which detects an internal pressure of the vapor purge system. The pressurizing section supplies the air for a predetermined time in a state where the vapor purge system is closed. When the internal pressure measured by the internal-pressure measuring section at the air supply is equal to or lower than a preset criterion pressure, it is judged that leak occurs.

摘要： PURPOSE:To restrict occurrence of vaporization of fuel in a type where arc-like passage grooves are formed on the inner side surface of suction side and dis charge side facing plates disposed surrounding an impeller rotated by a motor by forming the passage groove on the discharge side deeper than the passage groove on the suction side. CONSTITUTION:An impeller 14 of a pump part 100 is installed at one end of a drive shaft 5 fixed at an armature 4 of a motor part 200, and a suction side and a discharge side facing plate 113, 115 are disposed surrounding the impeller 14 close to each side surface of this impeller 14. Arc-like passage grooves 113a, 115a are formed at a facing positions in the facing plates 113, 115 along th outer circumference of the impeller 14, where the depth of the passage groove 113a in the suction side facing plate 113 is set smaller than the conventional ones, while the passage groove 115a in the discharge side facing plate 115 is set deeper. A suction port 11b and a discharge port 115b are formed at one end of the passage grooves 113a, 115b respectively through the facing plates 113, 115 at position facing each other.
