摘要： A laminated carbon brush for a liquid pump motor slides in a liquid fuel on a disk-like commutator. The laminated carbon brush includes two layers of a lower resistivity layer and a higher resistivity layer. In both the lower resistivity layer and the higher resistivity layer, circular directional resistivities of the brush along a circular direction in the rotation of the commutator are higher than non-circular directional resistivities of the brush along a radial direction of the commutator and a perpendicular direction to the sliding surface of the commutator. A non-circular directional resistivity of the higher resistivity layer are higher than or equal to 90,000 µ ©·cm. No spark discharges occur if the fuel pump motor is operated to output a high power.

摘要： PROBLEM TO BE SOLVED: To add 5 to 30 wt.% of a fibriform potassium titanate or montmorillonite to a carbon brush so as to solve the problems of the unevenness and abrasion of the surface of a commutator due to commutation sparks, between the carbon and the commutator of a fuel ejection pump.
SOLUTION: An abrasive having lower rigidity, which consists at least either a montmorillonite having an average second particle diameter of 0.1 to 1 μm of the brush, comprising mainly of carbon or of potassium titanate, having an average value of a fiber width of 0.2 to 0.6 μm, is added to the carbon brush, causing the surface of the commutator to be smoothed; while slightly suppressing the abrasion effect on the carbon commutator, thereby suppressing the occurrence of the commutation sparks. Accordingly, durability of the fuel ejection pump commutator is increased.
