Abstract

PURPOSE:To simplify the assembling of a pressure plate into a bore of a pump or motor housing and to decrease leak through the clearance by making a piercing hole slightly larger than a lunate sealing member and by tapering the suction side thereof toward its end to some extent. CONSTITUTION:A bore 14 is covered with a mounting flange 12, after a pressure plate 23, an internal gear 13 and a pinion 16 have been sequentially incorporated into the bore 14, while the pressure plate 23 is passed through its piercing hole 27 by a lunate sealing member 15 in axially movable confiquration. Therefore, even the internal gear 13 and the side face of the pinion 16 are work, the pressure plate 23 can be made to follow them. Further, since the piercing hole 27 is slightly lager than the lunate sealing member 15 and the suction side thereof is tapered toward its end to extent, the assembling of the pressure plate 23 into the bore 14 is simplified and leak through a clearance between the piercing hole 27 and the lunate sealing member 15 can be decreased.
