摘要： A rotary pump such as a trochoid pump is composed of a housing and a rotating structure including an inner rotor and an outer rotor. The rotating structure is rotatably enclosed in a rotor space formed in the housing. The rotor space is divided into a low pressure space communicating with an inlet port and a high pressure space communicating with an outlet port by a pair of peripheral seals disposed in radial grooves formed in an inner periphery of the housing and by a side seal disposed in an axial space between the rotating structure and the housing. The side seal is disposed in the axial space not to cover sidewalls of the radial grooves belonging to the high pressure space, so that the side seal is bent by the pressure in the high pressure space to effectively seal the axial space.

摘要： In the rotary pump, a sealing member is provided at a clearance between a casing and axial end surfaces of the inner and outer rotors, the sealing member extending from an outer circumference of the outer rotor, via the inner rotor between a drive shaft and a discharge port, to another circumference of the outer rotor so that brake fluid communication from the discharge port to an intake port may be prevented, but the brake fluid communication between the outer circumference of the outer rotor and almost all of teeth gap portions on a discharge port side and, further, between almost all of teeth gap portions on an intake port side and a clearance between the drive shaft and the inner rotor may be allowed.

摘要： In an inner wall surface of a casing, grooves are formed that correspond to end faces of an outer rotor and an inner rotor, and seal members are disposed within the grooves, the seal members presses against the end faces of the outer rotor and the inner rotor. Inclined portions are provided in sealing portions of resin members of seal members, the sealing portions covering a closed portion. With this configuration, an internal pressure in the closed portion causes the inclined portions to separate from an outer rotor and an inner rotor when a brake fluid pressure within the closed portion increases to the point that the brake fluid is excessively compressed, releasing the brake fluid that is inside the closed portion. It is therefore possible to prevent the brake fluid pressure from increasing excessively within the closed portion.

摘要： A bearing is located with movement of an outer race in the longitudinal direction of a drive shaft being restricted, and the drive shaft is fixed to an inner race with the press fit, so that, it is possible to prevent the drive shaft from escaping. In addition, the inner race is longer than the outer race. Therefore, it is possible to obtain sufficient strength of the press fit of the drive shaft in the inner race while suppressing the size of the outer race (in other words, suppressing the size of the pump device). As a consequence, the size of the pump device can be suppressed while increasing reliability of the function for preventing the drive shaft from escaping.

摘要： A bearing is located with movement of an outer race in the longitudinal direction of a drive shaft being restricted, and the drive shaft is fixed to an inner race 51c with the press fit, so that, it is possible to prevent the drive shaft from escaping. In addition, the inner race is longer than the outer race. Therefore, it is possible to obtain sufficient strength of the press fit of the drive shaft in the inner race 51c while suppressing the size of the outer race (in other words, suppressing the size of the pump device). As a consequence, the size of the pump device can be suppressed while increasing reliability of the function for preventing the drive shaft from escaping.

摘要： The curvature of a circular arc constituted by a side of a suction groove is made larger than that of a circular arc constituted by a side of a discharge groove. Thus, when the suction groove and the discharge groove are viewed in the axial direction of a drive shaft, the distance between the suction groove and the discharge groove in the radial direction of a rotary portion is short in a region intersecting with a line W perpendicular to a centerline, and increases in accordance with a decrease in distance from containment portions. It is therefore possible to ensure a sufficient distance between the discharge and suction grooves and enhance a total fluid pressure generated therebetween, and the contact surface pressure that is necessitated by a second side plate to obtain a press-back force when being in contact with an outer rotor and an inner rotor is reduced.
摘要翻译：由吸引槽的一侧构成的圆弧的曲率比由排出槽的一侧构成的圆弧的曲率大。因此，当在驱动轴的轴向上观察吸入槽和排出槽时，旋转部的径向方向上的吸入槽和排出槽之间的距离在垂直于线W的区域中短到中心线，并且随着距离容纳部分的距离的减小而增加。因此，可以确保排出和吸入槽之间的足够的距离，并增强其间产生的总的流体压力，以及当与第二侧板接触时获得压靠力所需的接触表面压力外转子和内转子减少。

摘要： In a rotary pump for a braking apparatus, a discharge trench is formed on an axial direction end surface of a second side plate that forms a mechanical seal. As a result, rotors are pressed back toward a side of a first side plate by a discharge pressure of brake fluid channeled to the discharge trench. Accordingly, a force pressing the rotors toward the second side plate is reduced and frictional resistance is reduced.

摘要： In a rotary pump in which axial end surfaces of outer and inner rotors is in pressurized direct contact with an axial end surface of a second side plate to form a mechanical sealing, both of the axial end surfaces of the outer and inner rotors and the axial end surface of the second side plate are provided with radial line grinding stripes. Teeth gap portions formed by the outer and inner rotors in mesh communicate with an outer circumference gap between the circumference of the outer rotor and inner circumference of a center plate and also with a shaft hole of the inner rotor through extremely slight gaps formed by concave and convex of the radial line grinding stripes so that contact surface between the outer and inner rotors and the second side plate is well lubricated to reduce torque loss.
