ポンピングチヤンバの容積最大位置を閉込みの基
準にしてロータの回転方向前方に吐出ポートを、
回転方向後方に吸入ポートを配置した歯数差が１
枚の内接歯車ポンプにおいて、ケーシング側に設
けられる最大容積ポンピングチヤンバの閉切り部
を吐出ポート側に拡張し、この拡張閉切り部と基
準閉込み部においてアウターロータ外周の支持面
であるケーシング内周面に設けた凹部とを油路で
連絡したことを特徴とする内接歯車ポンプ。 The discharge port is located at the front in the rotational direction of the rotor, with the maximum volume position of the pumping chamber created between the inner rotor and outer rotor as the reference for confinement.
The difference in the number of teeth is 1 with the suction port located at the rear in the rotational direction.
In this type of internal gear pump, the closed section of the maximum volume pumping chamber provided on the casing side is expanded toward the discharge port side, and the casing, which is the supporting surface of the outer periphery of the outer rotor, is connected to the extended closed section and the reference closed section. An internal gear pump characterized in that an oil passage communicates with a recess provided on an inner circumferential surface.
