Claims

[Scope of utility model registration request]

A cylindrical body is provided with a closing member such as a cover, gears are installed inside this body, and the shafts of these gears are inserted into bearings press-fitted into the closing member. In the gear pump or motor, a seal block is interposed between the outer circumference of the side plate and the inner circumferential surface of the body, and a loading area is formed on the outer surface of the seal block. It consists of a plate part that supports the block, and a support part that tightly contacts the inner peripheral surface of the body on the low pressure chamber side, which is the opposite side of the seal block, and at least at the boundary between the plate part and the support part. A gear pump or motor with a constricted part to reduce rigidity.
