Title (EN) VANE PUMP
(FR) POMPE À PALETTES
(JA) ベーンポンプ
Abstract:
(EN) A vane pump 100 is provided with: a high-pressure chamber 12 formed in a groove shape in a bottom part of a pump-accommodating concavity 10a, a working fluid being guided to the high-pressure chamber 12 through a first discharge port 9a and a second discharge port 9b; and a high-pressure passage 19 having an opening 19a that opens into the high-pressure chamber 12, the high-pressure passage 19 guiding working oil out of the high-pressure chamber 12. The first discharge port 9a or the second discharge port 9b is disposed so as to face the opening 19a of the high-pressure passage 19, and the flow channel cross-sectional area of the high-pressure chamber 12 is less than the total flow channel cross-sectional area of the first discharge port 9a and the second discharge port 9b.
(FR) L'invention concerne une pompe à palettes (100) qui comprend : une chambre à haute pression (12) réalisée sous forme de rainure dans une partie inférieure d'une concavité de logement de pompe (10a), un fluide de travail guidé vers la chambre à haute pression (12) à travers un premier orifice d'évacuation (9a) et un second orifice d'évacuation (9b) ; et un passage à haute pression (19) comportant une ouverture (19a) qui s'ouvre dans la chambre à haute-pression (12), le passage à haute pression (19) guidant l'huile de travail hors de la chambre à haute pression (12). Le premier orifice d'évacuation (9a) ou le second orifice d'évacuation (9b) est disposé de façon à faire face à l'ouverture (19a) du passage à haute pression (19), et l'aire transversale de canal d'écoulement de la chambre à haute pression (12) est inférieure à l'aire transversale totale de canal d'écoulement du premier orifice d'évacuation (9a) et du second orifice d'évacuation (9b).
(JA) ベーンポンプ100は、ポンプ収容凹部10aの底部に溝状に形成され、第1吐出ポート9a及び第2吐出ポート9bを通じて作動流体が導かれる高圧室12と、高圧室12に開口する開口部19aを有し作動油を高圧室12の外部へ導く高圧通路19と、を備え、第1吐出ポート9a及び第2吐出ポート9bのうちの一つは、高圧通路19の開口部19aに対向するように配置され、高圧室12の流路断面積は、第1吐出ポート9a及び第2吐出ポート9bの流路断面積の合計よりも小さい。
