Claims (1)
、両歯車の噛み合い部では歯列間に閉じ込み室が
形成される歯車ポンプにおいて、前記閉じ込み室
の容積最大値及び最小値をそれぞれＶｍａｘ及び
Ｖｍｉｎとすると、｛（Ｖｍａｘ−Ｖｍｉｎ）／
Ｖｍｉｎ｝×１００≦２％となるように前記駆動
歯車及び被駆動歯車の各部の寸法を設定すること
を特徴とする歯車ポンプ。 In a gear pump having a driving gear and a driven gear that mesh with each other, and in which a confinement chamber is formed between tooth rows at the meshing portion of both gears, the maximum and minimum volumes of the confinement chamber are defined as Vmax and Vmin, respectively. Then, {(Vmax-Vmin)/
A gear pump characterized in that the dimensions of each part of the driving gear and the driven gear are set so that Vmin}×100≦2%.
