摘要： A partition partitions off a motor chamber and a pump chamber, through which a cooling water flows, a substantially cylindrical-cup shaped rotor is arranged in the pump chamber, a circuit board is disposed in the motor chamber to be in parallel to an annular-shaped end surface of the rotor, a magnetism detecting element is mounted on that portion of the circuit board, which faces a magnet portion of the rotor, and exothermic electronic parts are mounted on the remaining portion of the circuit board. The magnetism detecting element and the exothermic electronic parts, respectively, are arranged in opposite positions in a substantially annular-shaped area of the circuit board, which faces the annular-shaped end surface of the rotor, and a thickness of an annular-shaped wall portion of the partition facing the annular-shaped end surface of the rotor is made thin in a portion adjacent to the exothermic electronic parts on condition that an annular-shaped surface of the annular-shaped wall portion on a side of the annular-shaped end surface of the rotor is a non-inclined flat surface.

摘要： A pump device includes a pump housing including a fluid chamber for inhaling a fluid flowing through the fluid chamber via an intake port and discharging the fluid to an outside via a discharge port, a motor housing including a stator, and a shaft whose one end projects into the pump housing and to which an impeller is assembled and whose the other end is rotatably supported by a first bearing portion within the motor housing. The pump device also includes a rotor assembled to the shaft and facing the stator, and a bearing plate disposed between the pump housing and the motor housing and including a second bearing portion rotatably supporting the shaft. The bearing plate is formed by a first fluid passage for leading the fluid to the bearing plate.
摘要翻译：泵装置包括：泵壳体，包括流体室，用于经由进气口吸入流过流体室的流体，并且经由排出口将流体排出到外部;马达壳体，包括定子;以及轴，其一端突出进入泵壳体并且组装有叶轮并且其另一端由马达壳体内的第一轴承部分可旋转地支撑。泵装置还包括组装到轴上并面向定子的转子和设置在泵壳体和马达壳体之间并包括可旋转地支撑轴的第二轴承部分的支承板。轴承板由用于将流体引导到轴承板的第一流体通道形成。
