摘要： A liquid pump has a DC motor and a pump in a cylindrical casing. A pair of brushes are slidably contacted with a commutator of an armature while being biased by springs. The specific resistance of the positive brush is lower than the specific resistance of the negative brush to enable the voltage drop at the brushes to be decreased and motor efficiency to be increased without increasing commutator wearing speed. The biasing force provided by the spring biasing the positive brush is lower than the biasing force provided by the spring biasing the negative brush.

摘要： A fuel supply apparatus includes a flow control valve, a housing, a movable portion, a compression coil spring and a coil constructed integrally with a fuel pump (or separately from the fuel pump). The movable portion may be made of magnetic material and attracted to the fuel downstream side against the spring force of the compression coil spring by an electromagnetic attracting force generated by an electric current supplied to the coil. A fuel drain opening can be created by aligning a first communication passage to release an excess part of the fuel passing through fuel passages back to the fuel tank through the drain passage in accordance with an engine operation condition.

摘要： There is disclosed a trochoid pump in which a friction between a rotor and its support portion is reduced, thereby reducing a drive torque and wear of these parts. An inner rotor of the trochoid-type fuel pump is rotatably supported by a bushing through a bearing. An outer rotor is rotatably received in an inner periphery of a spacer. A first groove is formed in a portion of the outer periphery of the bushing disposed close to a discharge port, and a discharge fuel is introduced into this groove. A second groove is formed in a portion of the inner periphery of the spacer disposed close to the discharge port, and the discharge fuel is introduced into this groove. Although the inner rotor is urged toward the bushing by the fuel pressure of the discharge port, the urging force to urge the inner rotor toward the bushing is weakened by the discharge fuel introduced into the first groove, thereby reducing a friction. Although the outer rotor is urged against the spacer, the urging force to urge the outer rotor against the spacer is weakened by the discharge fuel introduced into the second groove, thereby reducing a friction.
摘要翻译：公开了一种摆动泵，其中转子和其支撑部分之间的摩擦力减小，从而减少这些部件的驱动扭矩和磨损。次摆线型燃料泵的内转子通过轴承由衬套可旋转地支撑。外转子可旋转地容纳在间隔件的内周。第一槽形成在靠近排出口设置的衬套的外周的一部分中，并且排出燃料被引入到该槽中。第二凹槽形成在靠近排出口设置的间隔件的内周的一部分中，并且排出燃料被引入该凹槽中。虽然通过排出口的燃料压力将内转子推向衬套，但是通过引入第一槽的排出燃料减弱了将内转子推向衬套的推动力，从而减小了摩擦。尽管外转子被推靠在间隔件上，但通过引入到第二槽中的排出燃料来减弱推动外转子抵靠间隔件的推动力，从而减小了摩擦。

摘要： A vehicle fuel pump having an impeller on which close fins are formed continuously in the circumferential direction, and a motor supplied with a voltage from a vehicle power source to drive and rotate the impeller. A fuel in a pump chamber formed between the opposed surfaces of each adjacent a pair of close fins of the impeller is pressurized and forced out by the rotation of the impeller. The delivery pressure of the fuel pumped out of the fuel pump is set to a level higher than the pressure in an intake pipe communicating with the engine by about 2 to 3 kg/cm.sup.2, while the flow rate during engine operation is set to a range of 50 to 200 l/h. At least part of the side surface of one of each pair of close fins located on the downstream side with respect to the direction of rotation of the impeller is formed parallel to a plane perpendicular to the direction of rotation of the impeller, while an outer end portion of the side surface of the other close fin located on the upstream side is formed so as to be slanted relative to a plane perpendicular to the direction of impeller rotation so that the capacity of the pump chamber is increased, whereby the lowest flow rate in a state where the voltage supplied from the vehicle power source drops when the engine is started is set to 20 l/h or higher, thereby preventing engine starting failure.

摘要： Disclosed is a method of manufacturing an electromagnetic member having properties of magnetic anisotropy as well as electrical conductivity, comprising the steps of coating an outer circumferential surface of each of a plurality of magnetic strips with a first electrically conductive material to a predetermined thickness to thereby form a plurality of composite magnetic strips, binding the plurality of composite magnetic strips, and filling spaces among the plurality of composite magnetic strips in the bundle with a second electrically conductive material substantially the same as the first electrically conductive material. By this method, a mechanically strong electromagnetic member can be obtained in which adjusting the thickness of the first electrically conductive material, the ratio between the magnetic property and the electrically conductive property can be easily adjusted by adjusting the thickness of the first electrically conductive material and blow-holes can be prevented from being generated.

摘要： When an induction motor is speed-controlled with a variable frequency power supply including thyristor inverters, operating loss due to harmonics components is increased in a rotor of the induction motor. In order to diverge additional operating loss into an appreciable depth of the rotor to thereby suppress the increase in the operating loss, the rotor comprises a cylindrical member having a circumferential resistivity which is larger than axial and radial resistivities and circumferential permeability which is smaller than axial and radial permeabilities, and a core disposed in the cylindrical member and having an axial permeability which is smaller than circumferential and radial permeabilities.
