Abstract

An LPG bomb apparatus is provided, including: a fuel charging unit formed on a LPG bomb; a fuel conduit through which fuel flows from the fuel charging unit to a fuel pump; a first check valve that is formed on the fuel conduit inside the LPG bomb and sucks the fuel with a pressure of the fuel pump; and a second check valve that is formed on the fuel conduit inside the LPG bomb, is spaced apart from the first check valve, and discharges the fuel to be charged by the fuel charging unit to the LPG bomb.

Claims

1. A Liquefied Petroleum Gas (LPG) storage apparatus comprising:

a fuel charging unit formed on an LPG container to refill fuel into the LPG container;

a fuel conduit through which the fuel flows from the fuel charging unit to a fuel pump arranged outside of the LPG container;

a first check valve that is formed on the fuel conduit inside the LPG container and allows the fuel to flow through the fuel conduit when a pressure is generated in the fuel pump; and

a second check valve that is formed on the fuel conduit inside the LPG container, is spaced apart from the first check valve, and discharges the fuel to be charged by the fuel charging unit to the LPG container.

2. The LPG storage apparatus according to claim 1, wherein the fuel conduit comprises:

a liquid-phase charging pipe having an upper end connected to the fuel charging unit and a lower end extended to a bottom of the LPG container; and

a suction conduit that is connected to the liquid-phase charging pipe and transports the fuel to the fuel pump.

3. The LPG storage apparatus according to claim 2, wherein the liquid-phase charging pipe is made of a flexible material.

4. The LPG storage apparatus according to claim 2, wherein the liquid-phase charging pipe is a plastic tube.

5. The LPG storage apparatus according to claim 2, wherein the first check valve and the second check valve are formed on the suction conduit.

6. The LPG storage apparatus according to claim 5, wherein the first check valve and the second check valve are formed on a downstream side of the suction conduit.

7. The LPG storage apparatus according to claim 1, wherein an injection hole is formed on the upper end of the fuel conduit such that a part of the fuel that flows through the fuel conduit evaporates to a gas phase, in accordance with a ratio determined when charging the fuel, and the evaporated fuel flows to a gas-phase side V of the LPG container.

8. The LPG storage apparatus according to claim 1, wherein the first check valve has an umbrella shape.

9. The LPG storage apparatus according to claim 1, wherein the first check valve is opened while a vehicle is driven and the fuel inflows into the fuel pump therethrough.

10. The LPG storage apparatus according to claim 1, wherein the second check valve is opened to charge a liquid-phase side L of the LPG container with the fuel when a pressure generated in the fuel conduit is a set pressure or more when charging the fuel.

11. The LPG storage apparatus according to claim 1, wherein a quick connector is formed on the upper end of the fuel conduit to facilitate assembly of the fuel conduit and the fuel charging unit.
