Description
Claims (1)
- 噛合する一対の歯車と、これら歯車の両側方に配置され、且つ歯車の側面に摺動する摺動面を有する側板とを具備した歯車ポンプ又はモータであって、
少なくとも一方の前記歯車が、その側面に、前記側板の摺動面と略平行をなす摺動領域と、前記側板の摺動面と平行をなさず且つ当該摺動面との間に作動流体がくさび膜効果により粘性で引き込まれて流れ込み油膜圧力が発生し得るくさび状をなす隙間を形成する非摺動領域とを形成したものであり、前記非摺動領域を前記側面の外縁部全域に亘って形成するものとし、
前記歯車の回転動作に伴って前記くさび状をなす隙間にくさび膜効果による油膜圧力が発生するように構成した歯車ポンプ又はモータ。
