摘要:
A filtering device may includes a bag-shaped filter member that is capable of being connected to a fuel inlet port of a fuel pump disposed in a fuel tank in order to filtrate fuel drawn by the fuel pump, and a wall member that is connected to the filter member such that a fuel reservoir portion can be defined above the filter member.
摘要:
A fuel filter assembly incorporates a BLDC motor and control circuit configured to operate at a first rotational speed upon startup and switch to a second rotational speed when measured variables indicate that the filter assembly is filled with fuel. The first rotational speed is initiated as a default when power is applied to the control circuit. If the filter assembly has been serviced, it must be primed before resuming normal operation. The first rotational speed is significantly higher than the second rotational speed to reduce the amount of time necessary to prime the filter assembly. The control circuit is arranged to monitor a variable which corresponds to the torque necessary to drive the pump. When the pump is filled with air prior to priming, lower torque is required to drive the pump, which corresponds to lower current draw and power consumption at the BLDC motor.

A fuel supplier for an automobile equipped with a fuel tank and an engine has a reservoir, a fuel pump a suction filter and a fuel transfer device. The reservoir is disposed in the fuel tank and is formed in a sealed manner. The fuel pump is configured to supply fuel from the fuel tank to the engine. The suction filter is configured to filter fuel suctioned into the fuel pump. The fuel transfer device is configured to transfer fuel from the fuel tank into the reservoir such that fuel in the reservoir is pressurized due to transfer pressure of the fuel.

A fuel feed device (1) for a fuel tank (3) is presented. The fuel feed device (1) has a filter (9) with a filter housing (11). The fuel feed device (1) furthermore has a second ejector pump (21) with a second nozzle (23) and a second mixing tube (25). The second mixing tube (25) is arranged perpendicularly to a base of the fuel tank (3). The second ejector pump (21) is at least partially integrated into the filter housing (11).

A baffle for use in a fuel tank has a sidewall and an interior space. The sidewall is formed of a flexible material so as to be radially compressible. The compressibility of the sidewall allows the baffle to be inserted through a hole which is smaller in diameter than the uncompressed diameter of the baffle. The baffle is preferably also longitudinally compressible so that it can be mounted in fuel tanks of varying depths.

A baffle has a sidewall and an interior space sized to receive the in-tank pump. The sidewall is formed of a flexible material so as to be longitudinally compressible. The compressibility of the sidewall allows the baffle to be mounted in fuel tanks of varying depths. The baffle is used in a method for mounting an in-tank fuel pump in a fuel tank. The method includes the steps of cutting a hole in a top wall of the fuel tank, inserting the baffle into the tank through the hole, compressing the sidewall of the baffle so that the baffle extends between the top and bottom walls of the tank, installing the in-tank pump in the interior space of the baffle and installing a cover plate over the hole.

A suction filter may comprise a bag-shaped filter member and a passage member. The passage member is disposed in an internal space of the filter member. The passage member has a fuel passage and a plurality of openings, and guides fuel from the internal space to the outside of the internal space. The openings communicate the internal space of the filter member to the fuel passage. When the passage member is cut along a surface thereof perpendicular to a longitudinal direction of the passage member in each of the openings, a position on an outer circumferential surface of the passage member in the cut surface, in which the distance between the outer circumferential surface and the filter member is the smallest, is distant in a circumferential direction from a position on the outer circumferential surface where the opening is formed.

The invention relates to a fuel conveying device for conveying fuel towards an internal combustion engine. The fuel conveying device comprises a housing and a head connected to the housing. Further, a fuel pump is provided, having an electronically commutated brushless motor. The control electronics for the electronically commutated brushless motor of the fuel pump are carried by or arranged within and/or on the head or housing.
摘要:
A filter element is formed from a filter material configured to capture a foreign substance in fuel. A lower case is attachable to and detachable from a bottom portion of a housing in a movable direction. The housing and the lower case are configured to accommodate the filter element. The filter element defines a passage extending through the filter element in the movable direction. The passage is configured to accommodate the component. 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.
