Patent number: 7418948Abstract: A stator core of a motor arrangement includes six cores, which are arranged one after another in a circumferential direction. A bobbin, which is made of dielectric resin, is fitted to each core. Each coil is formed such that a winding is wound around the bobbin through a concentrated winding technique. Dielectric resin is filled between each circumferentially adjacent two teeth to cover each coil. Furthermore, the dielectric resin is molded to form clearances, each of which is formed between the corresponding circumferentially adjacent two teeth on a rotor side. Fuel, which is pressurized by a pump arrangement, passes an interior of the motor arrangement through a fuel passage, which is a gap between an inner peripheral surface of the stator core and an outer peripheral surface of the rotor, and also through the clearances.Type: GrantFiled: November 1, 2006Date of Patent: September 2, 2008Assignee: Denso CorporationInventors: Kiyoshi Nagata, Masaya Otake

Patent number: 7069914Abstract: A fuel feed apparatus including a sub-tank is received in a fuel tank having multiple tank sections. Multiple jet pumps respectively transfers fuel received in the tank sections into the sub-tank. Therefore, even if a fuel amount received in a single tank section decreases, fuel can be steadily supplied from another tank section. Intermediately pressurized fuel in a fuel pump is supplied to the jet pumps, so that fuel can be steadily supplied to the jet pumps regardless of fuel consumption amount in an engine. Fuel is drawn from an upstream side of a pressure regulator, and supplied to the jet pump. The pressure regulator has an urging unit, and controls fuel pressure without using a diaphragm. Therefore, the pressure regulator is simplified and downsized.Type: GrantFiled: September 28, 2005Date of Patent: July 4, 2006Assignee: Denso CorporationInventor: Kiyoshi Nagata
