摘要： A motor controller includes a temperature sensor configured to detect a temperature of a motor. An intermittent operation circuit allows the motor to intermittently operate at a rotation speed up to a phase before the motor reaches a rated rotation speed when it is detected that the motor temperature is at a low temperature range. The intermittent operation circuit includes a position fixing circuit configured to allow a constant electric current to flow through stator coils and to fix the motor in a stopped state. The intermittent operation circuit further includes a forced commutation circuit that allows the motor to rotate at a rotation speed up to the start-up rotation. The position fixing circuit allows the constant electric current to have a greater value as the temperature detected by the temperature sensor is lower, and allows the position fixing circuit and the forced commutation circuit to operate alternately.

摘要： A fuel supply device includes a fuel pump, a pump case, a cap, an O-ring, and a connection assembly. The pump case includes a case main body configured to receive the fuel pump and a discharge port connector. The cap includes a suction port connector. The O-ring is interposed between a fuel discharge port of the fuel pump and discharge port connector. The connection assembly includes a plurality of engagement projections and a plurality of engagement pieces configured to mate and engage with the engagement projections. The fuel discharge port of the fuel pump is configured to reach the O-ring coupled to the discharge port connector of the pump case simultaneous with the engagement between the engagement projections and the engagement pieces when the fuel suction port of the fuel pump and the suction port connector of the cap are connected together.

摘要： A pressure regulating valve includes a casing, a holder, a fixed valve, a movable valve, a spring member, a diaphragm, and a filter. The filter is configured to filter fluid flowing from a flow inlet of the casing into a pressure chamber. The filter includes a filtering part for filtering fluid and a holding part including a frame part for holding an outer periphery of the filtering part. An alignment structure configured to align the holding part at a predetermined position is provided between the holding part of the filter and the holder, or between the holding part of the filter and the casing.

摘要： A fuel supply device includes a fuel pump, a sub-tank configured to store a fuel, a leakage passage configured to return a part of a pressurized fuel discharged from the fuel pump into the sub-tank, and a fuel filter disposed at a bottom part of the sub-tank . The fuel filter includes a filter member that is configured to filter the fuel to be suctioned into the fuel pump. A downstream end of the leakage passage includes a linear passage part linearly extending from a position above the filter member toward the filter member. The fuel supply device also includes a direction change wall part configured to change the flow direction of the pressurized fuel jetted from the linear passage part so as to prevent the pressurized fuel from directly impacting the filter member.
