Title (EN) VANE PUMP
(FR) POMPE À AILETTES
(JA) ベーンポンプ
Abstract:
(EN) A vane pump 100 comprises a rotationally driven rotor 2, vanes 3 that are slideably inserted into the rotor 2, pump chambers 6 that are defined by spaces between neighboring vanes 3, inlet ports 14, 15 that guide operating fluid into the pump chambers 6, an intake pressure chamber 13 that is in communication with the inlet ports 14, 15 and stores the operating fluid, and an intake passage 12 that is connected to the intake pressure chamber 13 and has an intake aperture end 12a that provides an opening in an outer surface of a pump body 10. The intake pressure chamber 13 is lower than the intake aperture end 12a of the intake passage 12 while the vane pump 100 is mounted.
(FR) L'invention concerne une pompe 100 à ailettes comprenant un rotor entraîné en rotation 2, des ailettes 3 introduites par coulissement dans le rotor 2, des chambres 6 de pompe définies par des espaces séparant des ailettes voisines 3, des orifices d'entrée 14, 15 guidant un fluide de service dans les chambres 6 de pompe, une chambre de pression d'admission 13 en communication avec les orifices d'entrée 14, 15 et contenant le fluide de service, et un passage 12 d'admission communiquant avec la chambre de pression d'admission 13 et comportant une extrémité 12a d'ouverture d'admission qui fournit une ouverture dans une surface extérieure d'un corps 10 de pompe. La chambre de pression d'admission 13 est située à un niveau plus bas que l'extrémité 12a d'ouverture d'admission du passage 12 d'admission lorsque la pompe 100 à ailettes est montée.
(JA) ベーンポンプ100は、回転駆動されるロータ2と、ロータ2に摺動自在に挿入されるベーン3と、隣り合うベーン3の間に画成されるポンプ室6と、ポンプ室6へ作動油を導く吸込ポート14,15と、吸込ポート14,15に連通し、作動油が貯留される吸込圧室13と、吸込圧室13に接続され、ポンプボディ10の外面に開口する吸込開口端12aを有する吸込通路12と、を備える。ベーンポンプ100が搭載された状態で、吸込圧室13は、吸込通路12の吸込開口端12aよりも下方に設けられる。
