Claims (7)
前記コンプレッサインペラに回転軸を介して駆動力を伝達するよう構成されたモータと、
前記コンプレッサインペラの背面と隙間を介して対向するとともに前記回転軸を囲繞する背面側ケーシングと、
前記回転軸を回転可能に支持するように前記背面側ケーシングと前記回転軸との間に設けられた軸受と、
を備え、
前記背面側ケーシングは、前記コンプレッサインペラの前記背面に向かって突出する少なくとも一つの突起部を含む、
前記すくなくとも一つの突起部は、前記隙間の流路抵抗を増大し、前記隙間を前記コンプレッサインペラの径方向における内側へ流れる漏れ流れの進行を抑制する、電動過給機。 A compressor impeller,
A motor configured to transmit driving force to the compressor impeller via a rotation shaft,
A back side casing that faces the back side of the compressor impeller via a gap and surrounds the rotating shaft;
A bearing provided between the rear side casing and the rotating shaft so as to rotatably support the rotating shaft,
Equipped with
The rear side casing includes at least one protrusion protruding toward the rear side of the compressor impeller,
The electric supercharger , wherein the at least one protrusion increases the flow path resistance of the gap and suppresses the progress of the leakage flow that flows through the gap inward in the radial direction of the compressor impeller .
前記突起部の先端は、前記凹部の内側に位置する、請求項１に記載の電動過給機。 The back surface of the compressor impeller includes a recess,
The electric supercharger according to claim 1, wherein a tip of the protrusion is located inside the recess.
