Pump-less fuel supply system

Abstract

To provide a pump-less fueling system that does not result in dangerous situations such as the flooring becoming a sea of kerosene during fueling and is also difficult to leave an odor behind. 【Solution means】The tank 9 is stacked in two layers to create a head difference, and a nozzle 1 is attached to the lower part of the tank. When the cock is opened to allow natural fueling, when the (air holes) of the nozzle are blocked by the oil level, the air inflow is cut off and the kerosene inflow automatically stops.

Description

Technical Field

[0001] This invention relates to an oil supply system that does not require a pump to supply oil to a cartridge tank used in heating appliances or the like and automatically stops safely.

Summary of the Invention

Problems to be Solved by the Invention

[0002] Among the existing ones used for current oil supply, there are those that use batteries and a pico pump (dominant), but the kerosene is manually injected into the cartridge tank. If you accidentally leave the scene, it will overflow and the flooring will become a sea of kerosene. This is an extremely dangerous state, and it is very troublesome to clean up later, and there are problems such as an odor remaining.

Means for Solving the Problems

[0003] One tank (set of two identical ones) is used as a base, and another tank is placed on it to ensure a head difference. A nozzle is attached to the lower part of the tank, and the cock is opened to automatically supply oil to the cartridge tank. The nozzle has an air hole and a kerosene hole. When the oil level rises and blocks the nozzle (when the air hole is blocked), the inside of the tank can communicate with the outside atmospheric pressure, and the outside atmospheric pressure stops the outflow of kerosene.

Effects of the Invention

[0004] When the air hole at the tip of the nozzle is blocked by hydraulic pressure, the inflow of air stops, and at the same time, the outflow of kerosene automatically stops. Even if left unattended, the kerosene will not overflow and no pump is required.

Mode for carrying out the invention

[0007] Two identical tanks are set, and convex and concave parts are provided at the upper and lower parts of each tank respectively. One tank is used as a base, and the concave part of the upper (tank) firmly fits into the convex part of the lower tank used as the base to ensure stability and a drop. A nozzle is attached to the lower part of the tank placed on it, and a cock is provided on the nozzle.

Example

[0008] The valve integrating the nozzle with the tank has a male thread cut on the outside, and a packing with a tapered cross-section through which the nozzle passes is provided inside the valve attached to this. By tightening the valve, kerosene leakage can be prevented, and the nozzle can be fixed at an arbitrary angle. When refueling, loosen the valve, make the tip of the nozzle vertical, remove the cap at the tip, and open the cock to use. When the kerosene poured from the nozzle rises, the oil level blocks the air hole at the tip of the nozzle, and the inflow of air stops. Then, the air pressure in the tank connected to the outside air is blocked from the outside air pressure, and the outside air pressure acting on the oil level in contact with the tip of the nozzle is stronger than the pressure inside the tank, so the outflow automatically stops.

Claims

1. This pumpless fuel supply system is characterized by having a convex part at the top of the tank and a concave part at the bottom, and by having two identical tanks in a set, one of the tanks being used as a base and the other tank being placed on top, the convex part and the concave part being combined to stabilize the tank and ensure a drop, and by having a nozzle attached to the bottom of the upper tank and a cock attached to the nozzle.

2. A pumpless refueling system as described in claim 1, characterized in that the inside of the nozzle described in claim 1 has a kerosene hole and an air hole separately, the nozzle continues into the tank, and in order to prevent bleeding from the outer periphery of the nozzle, a gasket with a tapered cross section is passed through the nozzle and a valve is set to tighten the gasket, and by tightening the valve, bleeding is prevented and the nozzle can be fixed at any angle.
