摘要： PROBLEM TO BE SOLVED: To reduce a manufacturing cost and realize stably both reduction in leak flow in a pump section and reduction in sliding resistance. SOLUTION: Seal layers 52, 54 are arranged on both inner surfaces of casing pumps 38, 40 respectively facing the front and bock sides of an impeller 36. The seal layers 52, 54 are formed by stacking a single-layer thin film or multiple layers of thin films. The formation of a seal layer by a thin film is easy and low in cost as compared with the formation of a seal layer by using a cutting operation and is high in processing accuracy despite of these facts. Consequently, both the reduction in leak flow and the reduction in sliding resistance can be stably realized. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump capable of enhancing strength of resin pump casings and of preventing external force from being directly applied to the pump casings.
SOLUTION: Each of the pump casings 38, 40 is formed by integral resin molding of metallic members 50, 52. Part of the metallic members 50, 52 is exposed from resin. The exposed portions of the metallic members 50, 52 are made contact with an inner peripheral face of a housing 16 and an outer peripheral face 28a of a bearing 28, and resin portions are not directly made contact with them. Thus, the pump casing 38, 40 are strongly fixed to the inner peripheral face of the housing 16 and the outer peripheral face 28a of the bearing 28, so as to secure the strength with respect to press fitting and caulking. Moreover, since the resin portions of the pump casings 38, 40 do not directly receive external force, deformation of the pump casings 38, 40 and generation of creep after use can be prevented.

摘要翻译：要解决的问题：提供一种能够提高树脂泵壳体的强度并防止外力直接施加到泵壳体的燃料泵。解决方案：每个泵壳38,40由金属构件50,52的整体树脂成型形成。金属构件50,52的一部分从树脂露出。金属构件50,52的露出部分与壳体16的内周面和轴承28的外周面28a接触，并且树脂部分不直接与它们接触。因此，泵壳体38,40牢固地固定在壳体16的内周面和轴承28的外周面28a上，以确保相对于压配合和铆接的强度。此外，由于泵壳38,40的树脂部不直接受到外力，因此能够防止泵壳38,40的变形，使用后产生蠕变。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a motor for a fuel pump which can rotate at a high speed by reducing the weight of a rotor while ensuring the number of turns of a rotor coil equivalent to or higher than that of conventional one in a motor being integrated with the fuel pump.
SOLUTION: The rotor pole is provided with a bend where the coil passing distance is shortened between adjacent poles. A coil is wound around the bend. Since the coil passing distance between poles is shortened as compared with a conventional pole, the wire being used in the coil is shortened even if the number of turns is constant. Since the volume of wire is reduced, weight of the rotor can be reduced. Consequently, a lightweight rotor generating a rotating force equivalent to conventional one can be attained.

摘要翻译：要解决的问题：提供一种用于燃料泵的电动机，其能够通过减小转子的重量而高速旋转，同时确保转子线圈的匝数等于或高于常规的转子线圈的匝数电动机与燃油泵集成。
解决方案：转子极设有弯曲，其中线圈通过距离在相邻的极之间缩短。线圈缠绕在弯曲处。由于与常规的极点相比，极间的线圈通过距离缩短，即使匝数恒定，线圈中使用的线也被缩短。由于线的体积减小，所以能够减小转子的重量。因此，可以获得产生与常规旋转力相当的旋转力的轻型转子。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump having high motor torque while securing a sufficient fuel flow path. SOLUTION: A magnet 5 is formed in a ring shape encircling a rotor 21 over its all periphery and the magnet 5 and the rotor 21 are arranged extremely close to each other to secure high magnetic flux density. Absolutely, as the magnet 5 remains in the ring shape, the grooved fuel flow path 27 is formed in the inside face of the magnet 5. Thus, a sufficient flow rate of fuel is secured without increasing a clearance c between the rotor 21 and the magnet 5 while maintaining magnetic force. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump in which a length of a whole axial direction is shortened without shortening an axial length of bearings, a commutator and a coil, a size is reduced, and a weight is reduced.
SOLUTION: This fuel pump includes a space A formed around a shaft 7 of an upper side coil 19, and a space B formed around the shaft 7 of a lower side coil 19. In this fuel pump, when the bearings 13, 10 and the commutator 8 are disposed on the shaft 7, the lower end of the commutator 8 is disposed to be invaded into the space A, and the bearing 10 is disposed to be invaded into the space B. Thus, a distance between the bearings of the shaft 7 becomes a length of adding a length of the bearing 13, a length of the commutator 8, a length of a core 11, and a length of the bearing 10; and a distance between the bearings of the shaft 7 can be shortened twice as long as a protruding length of the coil 19.

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump in which a fuel is allowed to smoothly pass through the communication port of an impeller.
SOLUTION: The impeller 16 is provided with communication ports 16c for allowing recesses 16a on a front and a rear faces to communicate with each other. The communication port 16c is formed on the radially inner side of the recess 16a. When the impeller 16 is turned, the turning speed becomes slower in the portion of the communication port 16C as compared with the case wherein the communication port 16c is formed on the radially outer side. Therefore, the turning speed of the fuel in the vicinity of the communication port 16c in the recess 16a is reduced to facilitate passage of the fuel through the communication port 16c.

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump wherein a filter and a tank opening portion are hard to be contacted with each other when mounted into a fuel tank, and having a filter structure with an excellent mounting property.
SOLUTION: The filter 8 is mounted from a lower axial direction of a fuel pump 1, and a filter portion 10 surrounds an outer periphery of a pump portion 1b. Therefore, as compared with a conventional one, the length in a lateral direction is made to be short, so that the filter portion 10 is hard to contact with an inlet of the fuel tank 11 and easy to be mounted. Damage due to contacting is prevented.
