Abstract
A fuel tank includes an inlet port communicating with a fuel decelerating section of the tank in which the inflowing fuel is decelerated. The decelerated fuel is delivered to a fuel intake compartment of the tank which contains a filter. The filtered fuel is then delivered to a fuel storage area of the tank which includes a hose leading to an outlet port. A buoyant member is mounted on the inlet end of the hose to enable that inlet end to rise to or near the surface of fuel in the tank. Sediment drains are provided in the bottom of the tank for removing sediment from the fuel intake compartment and the fuel storage area.
Claims22
A fuel tank comprising:
- a tank body having a liquid fuel intake port communicating with an interior of said tank at an upper portion of said interior, and
- a wall arrangement dividing said tank interior into a fuel receiving area and a fuel storage area,
- said fuel receiving area communicating with said fuel intake port and including means for conducting a downward flow of fuel from said intake port while decelerating the speed of such downward flow of fuel,
- said fuel storage area communicating with a downstream end of said fuel receiving area at a location disposed below said fuel intake port, and
- a fuel outlet port communicating with said fuel storage area for withdrawing fuel therefrom, said fuel outlet port disposed below said fuel inlet port.
A fuel tank and a liquid fuel-burning heater connected to said fuel tank, said fuel tank comprising:
- a tank body having a liquid fuel intake port communicating with an interior of said tank at an upper portion of said interior, and
- a wall arrangement dividing said tank interior into a fuel receiving area and a fuel storage area,
- said fuel receiving area communicating with said fuel intake port and including means for conducting a downward flow of liquid fuel from said intake port while decelerating the speed of the fuel,
- said fuel storage area communicating with a downstream end of said fuel receiving area at a location spaced below said fuel intake port, and
- a fuel outlet port communicating with said heater and with said fuel storage area and disposed below said fuel intake port.
A fuel tank comprising:
- a tank body having a liquid fuel intake port communicating with an interior of said tank at an upper portion of said interior,
- a wall arrangement dividing said tank into a fuel-receiving area and a fuel storage area,
- said fuel-receiving area including a fuel decelerating section extending along a side of said tank from a top to a bottom of said side and including vertically space, generally horizontally oriented ribs having vertically spaced holes through which inflowing fuel flows downwardly, said holes being vertically non-aligned so that fuel passing downwardly through one hole must travel downwardly and horizontally to reach a subsequent hole, whereby the inflowing fuel decelerates,
- said fuel-receiving area including a fuel intake compartment overlying a portion of a bottom of said tank and communicating with a lower end of said fuel-decelerating section downstream of said holes, said fuel intake area including:
- a filter disposed above said bottom of said tank and oriented such that fuel received from said fuel-decelerating section flows upwardly through said filter, and
- a hole disposed in said wall arrangement above said filter for communicating said fuel intake compartment with said fuel storage area,
- said fuel storage area including an outlet port disposed below said fuel inlet port for the withdrawal of fuel.
