摘要： PROBLEM TO BE SOLVED: To provide a rotary pump device in which fluid leakage hardly occurs in space between a seal member and an oil seal, and in which the fluid blocked in the space hardly leaks outside from the oil seal.SOLUTION: By a two-stage seal structure of a seal member 130 and an oil seal 140, while brake fluid leakage from a first chamber to a second chamber is being suppressed, the brake fluid leakage from the second chamber to the outside is suppressed. Furthermore, at a contact part between a resin ring 131 and a shaft 54, a spiral groove 131h is formed on an inner peripheral surface of the resin ring 131. Thereby, a fluid force can be made to act in the direction pushing back the brake fluid entered inside the spiral groove 131h to the first chamber side according to the rotation of the shaft 54. Therefore, the brake fluid leakage from the first chamber to the second chamber becomes even less likely to occur.

摘要： PROBLEM TO BE SOLVED: To restrict a rotation moment from being generated in such a direction as one in which a location near a high pressure side pressure chamber in the end surface of a rotor is away from a seal surface so as to assure a sealing characteristic.SOLUTION: A supporting part 19bb is displaced to a side away from a seal surface 71b in an axial direction of a rotary shaft 54. With this arrangement above, in the case that a high pressure brake fluid pressure is applied to an outer peripheral surface of an inner rotor 19b, i.e. a surface of an outer tooth part and a force is applied in a diametral inner direction of the inner rotor 19b, it is possible to restrict a rotation moment from being generated in such a direction as one in which a location of the end surfaces of the inner rotor 19b, near the high pressure side pressure chamber is away from the seal surface 71b and it becomes more possible to assure a sealing characteristic. Further, a corner part 19bc at the seal surface 71b of the supporting part 19bb is arranged far from the seal surface 71b from the axial center of the inner rotor 19b. With this arrangement above, it is possible to generate a rotation moment for pushing the inner rotor 19b against the seal surface 71b.

摘要： PROBLEM TO BE SOLVED: To suppress a reduction in slide resistance between a side plate and an outer rotor or an inner rotor, and to suppress fluid leakage from between them.SOLUTION: An end face 72b of a second side plate 72 on which a mechanical seal is applied includes: a first face 72ba inclined with respect to a center axis Y; and a second face 72bb of which inclination angle is changed to be directed in a radial direction with respect to the first face 72ba. By forming such a second face 72bb, a clearance formed between the end face 72b and an outer rotor 51 can be narrowed, and an amount of a brake liquid intruding into the clearance can be reduced. With this configuration, the flow resistance between the second side plate 72 and the outer rotor 51 can be increased; the brake liquid hardly flows; and thus the leakage of the brake liquid from a high-pressure region to a low-pressure region can be suppressed.
