Summary:PROBLEM TO BE SOLVED: To accommodate a check valve in a pump outlet in a cover of an internal gear pump while saving a space, in a skid control type hydraulic vehicle brake system.SOLUTION: An internal gear pump includes a pinion 9 eccentrically positioned in a ring gear 11 and engaged with the ring gear, and a cover 4 for sealing an installation space 28. A pump outlet 29 of the internal gear pump lis led through the cover, and includes a check valve 38 to allow a liquid from the internal gear pump to flow, and to inhibit backflow of the liquid from the pump outlet to the internal gear pump. A filter 31 is disposed in a pressure field 20 of the cover 4. 【課題】スキッド制御式の液圧車両ブレーキシステムにおいて、逆止弁を、インターナルギヤポンプのカバーの中のポンプ出口に、省スペースで収納する。【解決手段】リングギヤ１１の中に偏心で配置され、これと噛み合うピニオン９、及び、組み込みスペース２８を密閉するカバー４を具備するインターナルギヤポンプであって、インターナルギヤポンプのポンプ出口２９がカバーの中に通っており、インターナルギヤポンプからの液体流を通し、ポンプ出口からインターナルギヤポンプへの逆流を阻止する逆止弁３８を具備する。また、カバー４において圧力フィールド２０の中にフィルタ３１を設ける。【選択図】図１
