摘要： A circumferential flow type liquid pump has, and a pump casing including a pump base and a pump cover. The pump casing rotatably supports an impeller and defines an elongated arcuate pump flow path along the outer periphery of the impeller and a suction inlet and a discharge outlet at both ends of the pump flow path. A plurality of gas venting holes are formed in a sliding surface of the pump cover along the pump flow path and communicate with the outside of the pump. Bubbles formed in the fuel in the pump flow path are positively discharged out of the pump casing assembly, and no vapor lock is caused.

摘要： An electric fuel pump is provided with an insulative holding member 20 for holding choke coils 16 and connecting portions 23 between the choke coils and lead wires (14) as well as between the choke coils and brushes 10, to be mounted in the interior of a pump frame 1. In this electric fuel pump, the insulative holding member 20 holds and fixes the choke coils 16 and the connecting portions around the same, thereby to protect the choke coils 16 and the nearby connecting portions against vibration and shocks applied to the fuel pump. The holding member 20 also insulates conductive parts so that the same are not in contact with a housing 1 of magnetic material or the like, thereby to improve insulativity.

摘要： A pressure regulator includes a case having a fuel inlet port for receiving fuel from a fuel pump, a fuel outlet port for delivering fuel to an internal combustion engine, and an opening. A valve element is attached to an elastic diaphragm that closes the opening. The valve element has a discharge passage for discharging excess fuel by allowing the interior and the exterior of the case partitioned by the elastic diaphram to communicate with each other. A spring seat is provided in the case in face-to-face relation to the valve element in such a manner as to close the discharge passage of the valve element during pressure contact. A spring is also provided for bringing the valve element into pressure contact with the valve seat with a predetermined pressure.

摘要： A circumferential flow type fuel pump has an impeller rotated by engagement between a hole in the impeller and a rotating shaft having a diameter smaller than that of the hole. The center ofthe hole is eccentric with respect to the center of the impeller in accordance with the difference between the diameter of the hole and the diameter in section of the rotating shaft, so that the center of the impeller coincides with the center of the rotating shaft during rotation of the impeller.
