Abstract
"BOMBA DE COMBUSTìVEL PARA BOMBEAR COMBUSTìVEL CONTIDO EM UM TANQUE DE COMBUSTìVEL". Uma bomba de combustível possuindo um rotor acionado por um motor elétrico é submersa em combustível contido em um tanque de combustível de um veículo automotivo. Quando o rotor é girado, o combustível é sugado na bomba de combustível e fornecido a um motor através da bomba de combustível. Um rotor do motor elétrico é rotativamente suportado por um par de mancais dispostos em ambas extremidades axiais do rotor. Cada mancal é composto de um corpo cilíndrico e um filme protetor cobrindo a superfície do corpo cilíndrico. O filme protetor é feito de um material possuindo uma propriedade resistente a ácido no sentido de proteger o corpo do mancal da erosão. é preferido prover o filme protetor de uma propriedade anti sulfatação em adição à propriedade resistente a ácido."FUEL PUMP FOR FUEL PUMP CONTAINED IN A FUEL TANK". A fuel pump having an electric motor driven rotor is submerged in fuel contained in a fuel tank of an automotive vehicle. When the rotor is turned, fuel is sucked into the fuel pump and supplied to an engine through the fuel pump. An electric motor rotor is rotatably supported by a pair of bearings arranged at both axial ends of the rotor. Each bearing is composed of a cylindrical body and a protective film covering the surface of the cylindrical body. The protective film is made of a material having an acid resistant property to protect the bearing body from erosion. It is preferred to provide the protective film with an anti sulfation property in addition to the acid resistant property.
