Abstract

Barrier system in the fuel tank (1) of a vehicle used in buses or similar vehicles to retain a certain amount of the fuel in at least one aspiration zone, which is dispersed by the effect of centrifugal force in a barrier assembly interlaced (4), while the fuel level is low and the vehicle is making its way along a road with sharp curves, characterized in that said barrier assembly (4) comprises: a. an outer barrier element (4a) that protects the fuel to be kept within the fuel tank against the flow effect of the fuel dispersed in the fuel tank, and b. an inner barrier element (4b) that protects the fuel to be kept inside the fuel tank against the effect of centrifugal force.

Description

Barrier system in the fuel tank of a vehicle

Object of the invention

This invention is directed to prevent the fuel that is dispersed in the fuel tank (1) by effect of centrifugal force when the vehicle travels down a road with sharp bends go down to the bottom of the suction level in at least one of the zones of aspiration.

State of the art

Depending on the type of vehicle and the type of engine, fuel tanks can be differentiated in terms of shape, volume and position. The functions of deposits of fuel are independent of the type of vehicle and the type motor. In general, a fuel tank should have some features such as the following: The deposit of fuel must be suitable for loading under conditions of safety and should be safe against losses and evaporation; the amount of fuel that should be measurable or observable stay in the warehouse; and the deposit must have protection against high pressure and must constantly feed the engine.

All modern fuel systems They feed the engine with a pump. The fuel is taken from tank with a suction tube. A minimum level of suction designing the suction tube so that it is slightly above the bottom surface of the deposit in order to prevent waste from being taken to the engine occur in the warehouse or could be taken inside the fuel tank to the engine.

Below the minimum suction level there is no  fuel feed While this application is intended to provide motor protection, it can give Place disadvantages in certain situations.

In current applications, since there is no any special mechanism in the fuel tank (1), at make the vehicle travel along a winding road the fuel level (5) in the fuel tank closed lowers until it becomes less than the minimum level of aspiration by a short space of time, and although this happens for space for a very short period of time, there is a risk that there is a cut in the fuel supply.

The divisions (2) that are put in the warehouse of fuel decrease the severity of this ripple that arises due to the movement of the vehicle, but cannot prevent that the fuel drops to below the suction level in virtue of the effect of centrifugal force.

Detailed description of the invention

The purpose of this invention is to place Barrier elements (4) at the bottom of the fuel tank (1) of the vehicle and protect and retain a certain amount of fuel, which is dispersed under the effect of force centrifuge, in a barrier assembly (4), while the level of fuel is low and the vehicle is traveling A road with sharp bends.

The barrier assembly (4) consists of an element  of external barrier (4a) that protects the fuel that is keeps inside against the effect of fuel flow dispersed, and of an inner barrier element (4b) that protects this fuel against the effect of centrifugal force.

The complex of suction tubes (3) that placed in the fuel tank to centralize the elements of barrier (4) extends almost to the fuel base in the inner barrier element (4b), and the suction edge of the suction tube complex (3) enters inside the inner barrier element (4b).

Thus, a longer period of feeding with the fuel that is prevented from leaving the set of barrier elements in the full turn turn to right or left.

Claims (2)

1. Barrier system in the fuel tank (1) of a vehicle used in buses or similar vehicles to retain a certain amount of fuel in at least one suction zone, which is dispersed by centrifugal force in a barrier assembly interlaced (4), while the fuel level is low and the vehicle is traveling along a road with sharp bends, characterized in that said barrier assembly (4) comprises: to. an outer barrier element (4a) that protects the fuel to be kept inside the tank of fuel against the flow effect of the fuel dispersed in the fuel tank, and b. an inner barrier element (4b) that protects the fuel to be kept inside the tank of fuel against the effect of centrifugal force. 2. Barrier system in the tank fuel (1) of a vehicle according to claim 1, which it comprises at least one complex of suction tubes (3) that is placed in the fuel tank to centralize the element  of inner barrier (4b) and whose suction edge enters the inside of the inner barrier element (4b).
