Abstract

PURPOSE:To make easier maintenance inspection at lower cost by changing flow by internal gear pump rotatable in both directions. CONSTITUTION:The gear pump body a is provided with the suction pipe a1 and the discharge pipes a2 and a3, and also the upper part of the motor axle 3 is fitted with the pinion 2. The inside of the pump housing 2 is rotatably provided with the internal gear 3 in which the pinion 2 is provided with the interposition of the motor axle 1 and gears into the internal gear 3 eccentrically. The discharge ports 7 and 8 are led to the suction pipe a1 and the discharge pipes a2 and a3 at an angle of approx. 120 deg. to the suction port 6. When the motor axle 1 is rotated clockwise, the pinion 2 and the gear 3 are turned in the same direction and thereby oil is sucked in by the port 6, pressurized gradually, and then discharged through the port 7 from the discharge pipe a2.
