Title:
GEAR PUMP, FUEL FEEDING DEVICE USING GEAR PUMP, AND GEAR MOTOR
Document Type and Number:
Japanese Patent JP3820779
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a gear pump and a fuel feeding device which can realize a small size and a light weight, as well as can reduce the inner leakagein a simple structure, and can obtain a high efficiency and a high discharge pressure in a wide scope from a low rotation area to a high rotation area.
SOLUTION: A sealed casing 37; a driving gear 31 and a driven gear 32 which suck and discharge a fluid by engaging each other in the casing 37, and have a shaft respectively; a side plate 34 to hold the gears rotatable and slidable; and a sealing member 38 to partition and seal the pressure side connecting to a suction port at the antigear side of the side plate, and the pressure side connecting to a discharge port 35; are provided. And a sealing member 38 is provided in order to make the suction port 35 part, and the periphery of a driving gear shaft 31a, into a suction port pressure area, and the periphery of a driven gear shaft 32a into a discharge port pressure area.
