Abstract: A fluid working machine comprises a rotor (7) with a blading (10) comprising 40 to 65 blades that radially project out of a body central and are suitably circumferentially offset on a plane normal to the axis of symmetry of the rotor, according to an appropriate spacing rule that can eliminate or appreciably attenuate the acoustic emission components that are mostly annoying to the human ear or at frequencies close to the resonance frequencies of other parts of the working machine.

Abstract: A pump unit (12) includes a pump housing (14), a pump cover (16), and an impeller (18) between the pump housing and pump cover. The pump housing and pump cover define a first channel (32) and a second channel (34) each having an inlet and an outlet. The impeller has first vanes (36) cooperating with the first channel and second vanes (38) cooperating with the second channel. The outlet of the second channel is constructed and arranged to provide fuel to an engine upon rotation of the impeller. A jet pump (38) is fluidly connected with the outlet of the first channel such that as the impeller rotates, the jet pump causes fuel to be drawn into the reservoir (37). Connecting structure (44, 44′) fluidly connects the first and second channels such that upon rotation of the impeller, fuel in the second channel flows into the first channel to prime the first channel.

A first group of concavities may be formed in an inner circumferential region of an intake side face of an impeller, and a second group of concavities may be formed concentrically in a region outside of the first group of concavities. A third group of concavities that communicates with the second group of concavities may be formed in a discharge side face of the impeller. The impeller is housed within a casing. A first groove that faces the first group of concavities and a second groove that faces the second group of concavities may be formed in the face of the casing that faces the intake side face of the impeller. A third groove that faces the third group of concavities may be formed in the face of the casing that faces the discharge side face of the impeller.

The motor unit has an armature that rotates and a commutator that rectifies electric current, which is supplied to the armature. The pump unit is driven by rotating of the armature. The fuel, the pressure of which is boosted by the pump unit, passes through the motor unit. The brush contacts the commutator. The pigtail is connected to the brush and supplies electricity to the armature via the brush. The pigtail is made from a copper alloy, which includes at least one of a corrosion-resistant metal that has higher sulfide formation energy than copper and a corrosion-resistant metal that has higher oxide formation energy than copper.

Abstract: A stator of an electric motor includes coil cores, bobbins and coils. The coil cores include six coil cores, which are arranged at equal angular intervals in a circumferential direction. The bobbins respectively cover outer peripheral surfaces of the coil cores, and the coils are respectively wound around outer peripheral surfaces of the bobbins. Among the six coils, each diametrically opposed two coils are electrically connected to each other through the corresponding connection line. Positioning members displace positions of the connection lines from one another, so that interference between the connection lines and interference between the connection line and the coils are limited.

Abstract: A fuel pump having a pumping impeller and an electric motor integrally contained in a cylindrical housing is submerged in a fuel tank of an automotive vehicle. The fuel pump pumps up fuel in the fuel tank and supplies pressurized fuel to an internal combustion engine. To make the fuel pump compact in size, i.e., small in diameter and short in length, a power-receiving connector of the fuel pump is coupled to a power-supplying connector by facing both connectors in the circumferential direction around the axis of the fuel pump. Elongate terminals in the power-receiving connector and brushes are positioned to overlap each other in the rotational direction of the fuel pump.
