Title (EN) VARIABLE DISPLACEMENT VANE PUMP
(FR) POMPE À PALETTES À DÉBIT VARIABLE
(JA) 可変容量形ベーンポンプ
Abstract:
(EN) This vane pump (100) is provided with: a rotor (20), a plurality of vanes (30), a cam ring (40), a pump chamber (41), an adapter ring (50), a pump body (60), a body-side lateral plate (70), and a body-side port (73), wherein the body-side lateral plate (70) has an expansion region (76a), a contraction region (76b), and a first pressure-receiving surface (77) that receives the pressure introduced through the body-side port (73) so as to oppose the cam ring (40), while the first pressure-receiving surface (77) is formed in such a manner as to be biased toward the contraction region (76b) side with respect to the rotary shaft of the rotor (20).
(FR) Cette pompe à palettes (100) est pourvue : d'un rotor (20), d'une pluralité de palettes (30), d'un anneau de came (40), d'une chambre de pompe (41), d'un anneau adaptateur (50), d'un corps de pompe (60), d'une plaque latérale côté corps (70) et d'un orifice côté corps (73), la plaque latérale côté corps (70) possédant une zone d'expansion (76a), une zone de contraction (76b) et une première surface de réception de pression (77) qui reçoit la pression introduite à travers l'orifice côté corps (73) de façon à s'opposer à l'anneau de came (40), tandis que la première surface de réception de pression (77) est formée de manière à être sollicitée vers le côté de la zone de contraction (76b) par rapport à l'arbre rotatif du rotor (20).
(JA) ベーンポンプ(100)は、ロータ(20)と、複数のベーン(30)と、カムリング(40)と、ポンプ室(41)と、アダプタリング(50)と、ポンプボディ(60)と、ボディ側サイドプレート(70)と、ボディ側ポート(73)と、を備え、ボディ側サイドプレート(70)は、拡張領域(76a)と、縮小領域(76b)と、ボディ側ポート(73)を通じて導かれる圧力をカムリング(40)に向けて受ける第1受圧面(77)と、を有し、第1受圧面(77)は、ロータ(20)の回転軸に対して縮小領域(76b)側に偏って形成される。
