Abstract: A support shaft connects between a flange and a pump unit. An intermediate member, which connects between the support shaft and pump unit, enables a relative positional change between the support shaft and the pump unit in an axial direction of the support shaft. The intermediate member limits a relative positional change between the support shaft and the pump unit in a circumferential direction of the support shaft. A resilient member is received in the support shaft and exerts a restoring force in an axial direction of the support shaft to urge the pump unit, which is movable relative to the support shaft in the axial direction, toward a bottom portion of the fuel tank.

Abstract: A fuel pump has a pump chamber accommodating a rotor member. The rotor member is rotatable to supply fuel to from a tank to an exterior of the tank. A case is supported in the tank. The case accommodates a part of the fuel pump. A pump bracket is located in the tank. The pump bracket is in a tubular bottomed shape having a sidewall portion in which a remaining portion of the fuel pump is inserted such that the sidewall portion surrounds a radially outside of the pump chamber of the remaining portion. The pump bracket is joined with the case to define a gap therebetween in a radial direction of the rotor member such that the pump bracket is movable relative to the case.

Abstract: A fuel supply system includes a plurality of fuel pumps, and one suction filter. The suction filter includes connection portions that are connected to pump inlets of the fuel pumps, and an interval adjusting member that adjusts the interval between the connection portions in accordance with the interval between the fuel pumps. Thus, it is possible to fit the suction filter to the fuel pumps without changing the interval between the fuel pumps. Because the interval between pump outlets is not changed, it is possible to minimize the problems that are likely to occur when the suction filter is fitted to the fuel pumps.

Abstract: A casing includes a container in which a float valve is disposed. When the float valve is closed, the casing keeps the float valve in a closed state for a relatively long period of time. A sub-float valve is provided below the container in the casing, and is closed by floating on fuel at the time of a turn of a vehicle or an automatic stop of first refueling. When the first refueling is completed, air in the sub-float valve is discharged, and the sub-float valve loses its floating function.

Abstract: A pump unit having a fuel pump and a suction filter is provided in a sub tank of a fuel tank. A filter element sheet for the suction filter is formed in a cup shape, a bottom wall portion of which faces to an inner bottom surface of the sub tank. A suction port of the fuel pump is opened to a fuel passage formed in the inside of the suction filter, so that filtered fuel is sucked into the fuel pump. Multiple mountain fold portions and multiple valley fold portions are formed on a side wall of the cup-shaped filter element sheet, to thereby increase surface area for filtering the fuel.

Abstract: A filter device includes a casing having an inlet for introducing fluid and an outlet for discharging fluid, and a filtering element disposed between the inlet and the outlet. The filtering element has an outer circumference face restricted from being deformed in a fluid flowing direction. The filtering element has an upstream end face on an upstream side in the fluid flowing direction, and a downstream end face on a downstream side in the fluid flowing direction. The filtering element is configured to be compressed toward the upstream end face by pressing the downstream end face.

Abstract: A filter device includes a filtering member having a rough part, which is comparatively low in a density of flow pores for flowing fluid, and a dense part, which is comparatively high in the density of the flow pores. The filter device further includes a support member that supports the filtering member and has an inflow passage and a discharge passage. The dense part supports the rough part, and is located between the rough part and the discharge passage, and is supported by a mechanical pressure applied by the support members. The filter device is capable of supporting the filtering member easily in a case member and securing a filtering area to enhance the performance of removing a foreign matter.

Abstract: A reservoir is located in a fuel tank. The reservoir is in a bottomed tubular shape having a periphery defining an opening, A lid member is located in the fuel tank and mounted to the periphery of the reservoir to close the opening. A pump unit is partially accommodated in the reservoir to discharge fuel stored in the reservoir to an exterior of the fuel tank. The pump unit is located at a position offset from a center axis of the lid member. The pump unit has a projection projected from the lid member to an exterior of the reservoir. A remaining quantity detector is configured to detect a quantity of fuel in the fuel tank. The remaining quantity detector is located at a remaining space remaining in the fuel tank. The remaining space is located on the lid member and located around the projection.

The component is configured to be attached to and detached from the housing together with the lower case when the lower case is attached to and detached from the housing.

Abstract: A casing has a vessel portion, in which a float valve unit is arranged. A fuel drain through-hole having a small diameter is formed at a closed end bottom of the vessel portion. A cross sectional area of the fuel drain through-hole is extremely smaller than an opening area of an inlet port, so that fuel discharging speed of the liquid fuel from the vessel portion through the fuel drain through-hole is suppressed to a small value. As a result, a fuel holding time of the liquid fuel in the vessel portion, which has entered into the vessel portion from the inlet port, is made longer.
