- 互いに平行な回転軸を中心として回転自在に設けられて噛合する第1ギヤおよび第2ギヤと、前記第1ギヤおよび前記第2ギヤを壁面部に歯先および両側面を摺接させた状態で保持する配設空間を有したケーシングとからなり、前記ケーシングに、前記第1ギヤおよび前記第2ギヤの回転に応じて流体が吸い込まれる吸込室および流体が吐出される吐出室が形成されてなるギヤポンプにおいて、
前記ケーシングの前記壁面部は、前記第1ギヤの前記回転軸を中心とする円弧状に形成されて前記第1ギヤの歯先を摺接させる第1仕切面と、前記第2ギヤの前記回転軸を中心とする円弧状に形成されて前記第2ギヤの歯先を摺接される第2仕切面と、前記吸込室側において前記第1仕切面と前記第2仕切面とを繋ぐ吸込側内周面と、前記吐出室側において前記第1仕切面と前記第2仕切面とを繋ぐ吐出側内周面と、前記第1ギヤおよび前記第2ギヤの前記両側面のうち一方の側面が摺接される第1側面と、前記両側面のうち他方の側面が摺接される第2側面とを有し、
前記仕切面と前記吐出側内周面との接続部に、前記仕切面と前記吐出側内周面との間に跨って前記第1側面側から前記第2側面側に向かって前記吐出室側に傾斜したテーパ面により形成されて、前記接続部の前記仕切面側近傍に位置する前記ギヤの歯間と前記壁面部とにより囲まれた歯先空間を前記ギヤの回転に応じて前記吐出室に徐々に連通させる流体連通部を有し、
前記テーパ面は、前記第1側面内において前記仕切面を区画する円弧線と前記吐出側内周面を区画する線分との交点を点P1とし、前記円弧線上において点P1から前記ギヤの前記回転軸を中心として当該ギヤの反回転方向に角度θだけ移動させた点を点P2とし、前記円弧線上における点P2での接線と前記線分との交点を点P3とし、前記仕切面と前記吐出側内周面と前記第2側面とが交差する交点を点P4としたとき、前記接続部を点P2、点P3および点P4を通る平面で切除した際に形成される点P2、点P3および点P4を頂点に持つ略三角形状の面取り部からなり、
前記角度θは、前記ギヤの歯のピッチ角度αの半分以上の角度からなることを特徴とするギヤポンプ。
