形成したことを特徴とするギアポンプ。 In a gear pump equipped with a bearing in which each gear shaft of a pair of gears is rotatably supported internally and each end face slides on the side surface of the gear, a groove bottom is formed on the periphery of the end face of each bearing facing the suction port. The radius is substantially equal to the tooth bottom radius of the gear, and the sum of the groove lengths connecting the groove ends of two mutually adjacent bearings with a straight line is substantially equal to the sum of the pitch circle diameter of the gear and the gear outer diameter. A gear pump characterized in that equal grooves are formed, and the shape of the opening of the gear portion of the suction port is formed in a rectangular shape that is wider than the tooth width of the gear by the groove width on both sides of the gear.
