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： A circumferential flow type liquid pump includes an impeller with vanes on its outer periphery, and a pump casing assembly defining an arcuate elongated 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. The pump casing assembly includes a radially-extending gas venting path which is opened in the inner periphery of the pump flow path near the impeller and separated by a step from the bottom of the pump flow path, and a through-hole much larger in sectional area than the gas venting path, through which the gas venting path is communicated with the outside of the pump casing assembly. Bubbles formed by vaporization of the fuel in the pump flow path are positively discharged from the pump casing assembly, and no vapor locking is caused.

摘要： A circumferential flow type fuel pump has a circumferential fuel flow passage provided around an impeller and a gas discharging hole formed in the inner wall of the fuel flow passage in such a manner that the fuel flow passage is communicated with the outside of the fuel pump. The upstream and portion of the fuel flow passage extends to a position near the gas discharging hole and is formed into a flow passage enlarging part by increasing its sectional area radially outwardly, whereby the pumping capacity is substantially maintained unchanged even under severe operation conditions such as at a high fuel temperature.

摘要： A motor-operated pump of the in-tank type including a motor for driving the pump, the motor having a commutator; a bracket covering one end of the motor disposed adjacent to the commutator; a brush held against the commutator through a through hole formed in the bracket; and a bearing for supporting a shaft of the motor. An annular projection is formed on a central portion of a surface of bracket disposed in opposed relation to the commutator, and the annular projection is formed integrally with the bracket. Alternatively, an annular projection is formed on a central portion of the commutator disposed in opposed relation to the bearing, and the annular projection is made of an electrically insulating material constituting the commutator, and is formed integrally with the commutator.

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.

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.
