摘要： A rotating pump includes an outer rotor and an inner rotor. The inner and outer rotors are rotated by a drive shaft between a first side plate and a second side plate to pump put fluid. The first side plate faces the inner and outer rotors and has a first surface and a second surface. The first surface is inclined to an axial direction of the drive shaft to create a wedge-shaped gap between itself and one of the inner and outer rotor. The second surface extends more parallel to a direction perpendicular to the axis direction of the drive shaft than the first surface does. The geometric configurations of the first and second surfaces serve to minimize the leakage of the brake fluid without sacrificing a reduction in resistance to sliding motion of the inner rotor and the outer rotor on the second side plate.

摘要： A rotary pump has a linear groove formed on an end surface of a second side plate of an outer rotor. Thereby, it becomes possible to generate a force for pushing back the outer rotor to a sealing member side, and thus it becomes possible to reduce load applied to the second side plate. As a result, contact resistance between the outer rotor and the second side plate becomes smaller, and smoother pumping operation becomes possible. Further, since the force for pushing back the outer rotor to the first sealing member side is generated in the linear groove, it is possible to reduce an amount of decrease in a contacting area with the outer rotor and the second side plate, thereby reducing an amount of wear of the outer rotor and the second side plate.

摘要： A gear pump apparatus is equipped with a pump and a sealing mechanism which is made up of an outer member, an inner member, and a rubber member fit between the outer and inner members. The inner member has a pressure-exerted surface to which pressure, as produced by contact of the rubber member with the inner member arising from application of discharge pressure of the pump, is applied. The pressure-exerted surface has a flange which creates thrust to move the inner member away from the gear pump, thereby bringing the inner member against an inner wall of a pump casing to develop a hermetical seal between a high-pressure region and a low-pressure region within the pump casing. This eliminates the leakage of pressure and ensures torque required for a pumping operation of the pump.

摘要： A rotary pump includes a first side plate and a second side plate between which an outer rotor and an inner rotor are arranged. The second side plate has a concave portion on a surface adjacent to a maximum gap portion relative to a drive shaft. The concave portion is located in an outer teeth passing section which is defined between a line on which a teeth tip of an outer teeth part of the inner rotor passes in response to rotation of the inner rotor and a line on which a teeth bottom of the outer teeth part of the inner rotor passes in response to rotation of the inner rotor. The concave portion communicates with one of a plurality of gap portions while the inner rotor is rotated.
