Abstract
A submersible fuel filter device (1) of suctional type is connectable to the end of a fuel inlet hose (2) in a fuel tank and comprises a filter (3) consisting of porous plastic with a surrounding outer wall (10) with an upper border (11), a lid (4) provided with an outlet opening (24) that covers the filter (3) and is connected to the outer wall's upper border. The filter is embodied like a cup-shaped body and has a through flow thickness, or material thickness, which is considerably smaller than the other dimensions of the body, and its porosity is less than 10 μm. The inlet suction hose (2) is connected to said outlet suction opening (24).
Claims9
A submersible, suction fuel filter device (1) connectable to an end of a fuel inlet hose (2) in a fuel tank, the device comprising:
- a lid (4) having an outlet suction port (24), the inlet hose (2) being connectable to the outlet suction port (24);
- and
- a filter (3) having an outer peripheral wall (10) extending along an axis (14) and an inner peripheral wall (13) extending along the axis (14), the outer and inner peripheral walls (10 and 13) bounding a filtration chamber (15), the outer and inner peripheral walls (10 and 13) being defined by a contiguous porous plastic filtering material that also defines a connection of the filtering material joining the outer and inner peripheral walls (10 and 13), an inner side of the lid (4) being engaged with the outer peripheral wall (10) at a distal end from the connection of the outer and inner peripheral walls (10 and 13), the inner peripheral wall (13) extending from the connection of the outer and inner peripheral walls (10 and 13) to a distal end located promiate the lid (4).
