てなるギヤポンプ又はモータ。 A bush or a side plate is provided on the side surface of the gear, and a high pressure area and a low pressure area are defined on the outside of the bush or side plate, which is the opposite side of the gear. In a gear pump or motor, an intermediate pressure area is defined in a portion corresponding to a rotational position where the pressure of The pressure area and the tooth groove side of the gear are communicated through two pressure transmission paths, and the opening end of one pressure transmission path on the gear side is connected to the low pressure side where the tooth groove pressure changes from low pressure to high pressure. The other pressure transmission path is made to communicate with the high pressure side while maintaining the throttling function, and the tooth groove position where the other pressure transmission path opens is communicated with the discharge port. A gear pump or motor with an open speed slot.
