Abstract | Provided is a fuel pump module configured so that an increase in the temperature of winding wires is suppressed and so that the efficiency of a fuel pump is increased. A fuel pump module is provided with: a motor section (60) having stator sections (61) which are formed by winding coils (61b) in winding grooves (61d) in stator cores (61a), the motor section (60) also having a rotor section (40) which is rotatably supported within the stator sections (61), the motor section (60) further having a yoke (10) which is formed in a cylindrical shape and which has the stator sections (61) secured to the inner peripheral surface of the yoke (10); and a pump section (50) for supplying fuel using an impeller (20) engaged with the rotor section (40) and driven and rotated. Through-hole flow passages (70) serving as fluid passages through which the fuel flows are provided in the winding grooves (61d) in the stator sections (61).
La présente invention se rapporte à un module de pompe à carburant conçu de sorte qu'une augmentation de la température de fils de bobinage soit supprimée et de sorte que l'efficacité d'une pompe à carburant soit améliorée. Un module de pompe à carburant est doté : d'une section moteur (60) possédant des sections stator (61) qui sont formées par des enroulements de bobinage (61b) dans des rainures de bobinage (61d) dans des noyaux (61a) de stator, la section moteur (60) comportant également une section rotor (40) qui est supportée rotative dans les sections stator (61), la section moteur (60) comportant en outre une culasse (10) qui a une forme cylindrique et qui a les sections stator (61) fixées à la surface périphérique intérieure de la culasse (10) ; et d'une section pompe (50) destinée à acheminer le carburant à l'aide d'un impulseur (20) en prise avec la section rotor (40) et entraîné et mis en rotation. Des passages d'écoulement (70) à trous traversants servant de passages de fluide par lesquels s'écoule le carburant sont disposés dans les rainures de bobinage (61d) dans les sections stator (61).
巻線の温度上昇を抑え、燃料ポンプの効率を高めた燃料ポンプモジュールを得る。ステータコア(61a)の巻線溝(61d)にコイル(61b)が巻回されたステータ部(61)と、このステータ部(61)内に回転自在に支持されたロータ部(40)と、円筒状に形成され内周面にステータ部(61)が固着されるヨーク(10)とを有するモータ部(60)、ロータ部(40)に係合して回転駆動されるインペラ(20)により燃料を送給するポンプ部(50)を備え、ステータ部(61)の巻線溝(61d)の中に、燃料を流通させる流体通路となる貫通孔流路(70)を設けるようにした。 |
