Zusammenfassung: | To provide a swash plate type axial piston pump motor in which a valve plate in slide contact with a cylinder block can be easily placed at a pump main body coaxial therewith.SOLUTION: A plurality of pistons 17 is arranged at a cylinder block 15 which is accommodated in a main body 1, and engaged with a rotating shaft 7 in a rotation direction so as to be freely reciprocal in an axial direction. A tip part of each of the pistons 17 comes in slide contact with a swash plate 14 to set a reciprocation amount of the piston 17. There is provided a valve plate 28 in which suction/discharge ports 29 and 30 for allowing the circulation of fluids while being in slide contact with the cylinder block 15 are formed. The main body 1 constitutes lid members 3 and 4 by spigot-joining them into an accommodation hole 5 of a housing 2 which accommodates the cylinder block 15 therein. The rotating shaft 7 is rotatably pivoted to the lid members 3 and 4 .The valve plate 28 is placed at the main body 1 coaxial with the rotating shaft 7 by spigot-joining an external periphery to the accommodation hole 5 which spigot-joins the lid member 4 thereto.SELECTED DRAWING: Figure 1
【課題】シリンダブロックと摺接する弁板を回転軸と同芯にポンプ本体へ簡単に配置する斜板式アキシャルピストンポンプ・モータを提供する。【解決手段】本体1内へ収装して回転軸7と回転方向に係合したシリンダブロック15には、軸方向へ往復動自在に複数のピストン17を配置する。各ピストン17の先端部が斜板14に摺接して各ピストン17の往復動量を設定する。シリンダブロック15と摺接して流体を流通する吸排ポート29、30を形成した弁板28を備える。本体1は内部にシリンダブロック15を収装したハウジング2の収装孔5に蓋部材3、4をインロー嵌合して構成する。回転軸7は蓋部材3、4へ回転自在に軸支する。弁板28は蓋部材4をインロー嵌合する収装孔5に外周をインロー嵌合して回転軸7と同芯に本体1へ配置した。【選択図】図1 |
