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： A pump apparatus includes a housing. A rotor is eccentrically accommodated in the housing. A motor rotates the rotor in the housing. A vane is substantially radially movable relative to the rotor. The vane has a radially outer end that is slidable relative to an inner circumferential periphery of the housing as the rotor and the vane rotates for increasing or decreasing pressure of gas. A pressure sensor detects pressure of the gas. A control unit that evaluates whether an adherence abnormality, in which the vane adheres to the rotor, occurs in accordance with both a detection signal of the pressure sensor and electricity supplied to the motor when the motor rotates the rotor. When the control unit determines the adherence abnormality to be caused, the control unit operates the motor to remove the vane from the rotor.

摘要： A detector for detecting evaporated fuel leakage from a fuel tank is connected to the fuel tank through a canister for absorbing evaporated fuel. When an engine is not in operation, air in the fuel tank is sucked by a pump installed in the detector. If the pressure in the fuel tank decreases to a predetermined level, it is determined that the evaporated fuel leakage is within a permissible range. An orifice passage, formed in the detector, connecting a tank passage to a sensor passage communicating with a sensor chamber where a pressure sensor is disposed is slanted relative to the tank passage to shorten the passage distance up to the pressure sensor. Further, the orifice passage is connected to the sensor passage at an obtuse angle to reduce a pressure loss in the passages. Thus, the leakage of the evaporated fuel is surely detected while making the detector compact.
