Abstract
A fuel introduction member is connected to an open end of a siphon tube which constitutes a part of a fuel tank. The fuel introduction member is provided with an opening through which a fuel is introduced from the tank into the siphon tube and from the siphon into the tank, a lid portion which is swung by the hydraulic pressure from the siphon tube so as to open the opening, and a float member which floats on the fuel in accordance with the rise of a fuel liquid surface in the tank to displace the lid portion in order to open the opening.
Claims12
A fuel tank comprising:
- a main tank for storing fuel and a sub-tank for storing the fuel;
- a negative pressure generator arranged in one of said main tank and said sub-tank;
- a siphon tube, which extends between the main tank and the sub-tank and is operatively connected with said negative pressure generator, and which transfers the fuel by said negative pressure generator;
- and
- a fuel introducing member connected to at least one open end of the siphon tube,
- wherein the fuel introducing member comprises:
- a base member having an opening formed therein for introducing the fuel into the siphon tube from the interior of the main tank or the sub-tank as well as for introducing the fuel into the interior of the main tank or the sub-tank from the siphon tube;
- a lid which is displaced by liquid pressure from the siphon tube so as to open the opening when a gaseous layer exists in an interior of respective one of said main tank and said sub-tank;
- and
- a float member, which, by rising of the liquid level of the fuel in the main tank or the sub-tank, floats on the fuel and then causes the lid to be displaced, to thereby open the opening;
- and
- wherein the float member floats on the fuel stored in one of the main tank and the sub-tank, whereby the fuel introduced from the opening is drawn in the siphon tube by the negative pressure generator and the fuel is transferred to the other of the main tank and the sub-tank.

- and
- a fuel introducing member connected to at least one open end of the siphon tube,
- wherein the fuel introducing member comprises:
- a base member having an opening formed therein for introducing the fuel into the siphon tube from the interior of the main tank or the sub-tank as well as for introducing the fuel into the interior of the main tank or the sub-tank from the siphon tube;
- a lid which is displaced by liquid pressure from the siphon tube so as to be capable of opening the opening;
- and
- a float member, which, by rising of the liquid level of the fuel in the main tank or the sub-tank, floats on the fuel and then causes the lid to be displaced, to thereby open the opening;
- and
- wherein the float member floats on the fuel stored in one of the main tank and the sub-tank, whereby the fuel introduced from the opening is drawn in the siphon tube by the negative pressure generator and the fuel is transferred to the other of the main tank and the sub-tank;
- and
- wherein the lid is displaced independently from the float member for thereby opening and closing the opening.
