摘要： A motor-driven fuel pump, wherein permanent magnets (30, 31) are disposed on both sides of a rotor (16), with respect to its centerline, which crosses perpendicularly to the direction of a load applied to an impeller (4) by a pressure distribution inside a pump flow path (7), and the axial center (31a) of the permanent magnet (31) is disposed offset from the axial center (30a) of the other permanent magnet (30) to the impeller (4) side so as to generate a torque on the rotor (16), whereby a load applied to bearings (17, 18) is reduced to make it difficult for a pump efficiency to lower and the bearings (17, 18) to wear.

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.
