Claims (1)
ケースとポートブロツク３との間に、ポートブロ
ツク３側に係止して回転不能とする摺接プレート
を介装したものにおいて、該ポートブロツク３の
取付面側にリーク圧油排出溝を一体成形したこと
を特徴とするアキシヤルピストン機構。 In a device in which a sliding contact plate is interposed between the cylinder case of the hydraulic pump P and the hydraulic motor M and the port block 3 to lock onto the port block 3 side and prevent it from rotating, the mounting surface side of the port block 3 is interposed. An axial piston mechanism characterized by a leak pressure oil drainage groove integrally molded into the axial piston mechanism.
