摘要： A housing of a fuel vapor leak check module is arranged close to a canister by inserting a canister port into the canister. A distance between the canister and the leak check module is reduced. A centerline of the canister port is approximately parallel to a centerline of an atmospheric vent port. A brushless motor of which axial length is relatively short drives a pump so that the housing is formed stepwise at the side opposite to the canister. A connector is disposed on the housing accommodating the pump to reduce a dead space.

摘要： A fuel vapor leakage check module has a canister port which is provided so that the port can be opened to the air and is connected to the interior of a fuel tank through a canister for absorbing fuel vapor produced in the fuel tank. A pump depressurizes or pressurizes the interior of the fuel tank through the canister port. A connecting passage which is coaxially provided in the canister port, is connected to the canister port. The connecting passage is depressurized or pressurized by the pump. A standard orifice is coaxially provided in the connecting passage and reduces the passage area of the connecting passage.

摘要： The present invention relates to a 3-position rotational actuator which obtains three stable points by two pairs of field poles, in which the magnetic flux to a rotor due to one pair of field poles of a stator for maintaining the rotor at the first stable point is substantially equal to the magnetic flux to the rotor due to the other pair of field poles of the stator for rotating the rotor from the first stable point. The magnetic flux density of the other pair of field poles of the stator applied to the rotor is set to be smaller than the magnetic flux density of the one pair of field poles of the stator. Therefore, the detention torque can be maintained to the same degree and the drive torque can be improved.
