Description

SPECIFICATION AN IMPROVEMENT IN FUEL SUCTION SYSTEM TECHNICAL FIELD
The present invention relates to a fuel suction system developed for providing suctioning of the fuel in a more efficient manner during provision of fuel from the main fuel tank and from the auxiliary fuel tank in agricultural vehicles.
PRIOR ART
In agricultural vehicles, there is a main fuel tank and an auxiliary fuel tank placed in a connected condition to each other by means of a fuel passage throat. The intake of the fuel into the engine is provided by means of a fuel suction system. The fuel suction system basically comprises a suction pipe connected to the main fuel tank and fuel is fed to the engine by means of said suction pipe. The auxiliary fuel tank provides fuel addition to the main fuel tank through the passage throat automatically as the fuel existing in the main fuel tank decreases. Thus, increase in the usable fuel volume is provided.
The media, where the agricultural vehicles are used, in general consist of sloped fields. In agricultural vehicles used on sloped fields, the movement of the vehicle according to the field structure leads to sloping of the fuel depots in accordance with the field slope together with the agricultural vehicle. This leads to movement of the fuel, provided in the fuel depots, between the main fuel tank and the auxiliary fuel tank. Particularly in cases where the fuel amount is reduced and in cases where the agricultural vehicle is in sloped form in a manner leading to accumulation of the whole fuel in the auxiliary fuel tank, no fuel remains inside the main fuel tank. When the level of fuel existing in the main fuel tank falls under the suction point, air is suctioned by the suction pipe and air is transferred into the engine. Stop occurs in the air suctioning engine. The stop occurring in the engine cannot be eliminated by means of fuel addition and the vehicle shall be brought to the service. The sloped field conditions lead to failures in the agricultural vehicles, and as a result, maintenance costs increase and process durations become longer. As a result, because of all of the abovementioned problems, an improvement is required in the related technical field. BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a fuel suction system which will provide the fuel level of agricultural vehicles, to stay above the suction point, in sloped field conditions, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.
The main object of the present invention is to provide a fuel suction system developed for providing realization of uninterrupted fuel suction independently from the slope of the agricultural vehicle on sloped field.
Another object of the present invention is to provide a fuel suction system which will prevent diverging of the fuel from the fuel suction point in agricultural vehicles used on sloped field. In order to realize all of the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention is a fuel suction system providing drawing of the fuel, existing in an agricultural vehicle, having a fuel depot comprising a main fuel tank and an auxiliary fuel tank connected to said main fuel tank through a lower throat section, by means of a suction pipe from a suction point provided in the main fuel tank. Accordingly, said fuel suction system is characterized by comprising a check valve provided in the lower throat section in order to realize single direction fuel flow from the auxiliary fuel tank towards the main fuel tank in order to provide sufficient fuel level in said suction point in field conditions where the fuel depot is provided in a negative or positive slope angle.
In a preferred embodiment of the subject matter invention, said check valve comprises valve lips which open in accordance with the pressure applied by the fuel and which permit fuel passage to the main fuel tank. In another preferred embodiment of the subject matter invention, said valve lip is made of rubber material in a manner providing sealing by means of the effect of hydrostatic pressure at the lower throat section.
In another preferred embodiment of the subject matter invention, there is an upper throat section embodied between the main fuel tank and the auxiliary fuel tank in a manner increasing the fuel passage speed from the auxiliary fuel tank to the main fuel tank during filling of the fuel depot. In another preferred embodiment of the subject matter invention, there are throat hoses for the lower throat section and the upper throat section embodied for connecting the main fuel tank and the auxiliary fuel tank to each other, and clamps for providing fixation of said throat hoses.

In this detailed description, the subject matter fuel suction system (20) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
In Figure 1 and Figure 2, the views of the fuel depot (10) to which the subject matter fuel suction system (20) is connected are given on the flat and sloped floor. Said fuel depot (10) basically comprises a main fuel tank (1 1 ) and an auxiliary fuel tank (12). Said main fuel tank (1 1 ) comprises a main tank upper throat (1 1 1 ) and a main tank lower throat (1 12) embodied at the continuation of each other. Said auxiliary fuel tank (12) comprises an auxiliary tank upper throat (121 ) and an auxiliary tank lower throat (122) embodied at the continuation of each other. The main fuel tank (1 1 ) and the auxiliary fuel tank (12) are connected to each other such that the main tank upper throat (1 1 1 ) and the auxiliary tank upper throat (121 ) correspond to each other and such that the main tank lower throat (112) and the auxiliary tank lower throat (122) correspond to each other. When the main tank upper throat (1 1 1 ) and the auxiliary tank upper throat (121 ) are joined, they form an upper throat section (13). When the main tank lower throat (1 12) and the auxiliary tank lower throat (122) are joined, they form a lower throat section (14). The connection of the main fuel tank (11 ) and the auxiliary fuel tank (12) is provided by means of throat hoses (15) positioned in a manner covering the upper throat section (13) and the lower throat section (14). Said throat hoses (15) are tightened from the two ends by means of clamps (16), and they are fixed on the throats. There is also a filling inlet (17) in the auxiliary fuel tank (12). The filling of the fuel (30) into the fuel depot (10) is provided by means of flowing of the fuel from said filling inlet (17) to the auxiliary fuel tank (12) and afterwards by means of fuel (30) passage to the main fuel tank (1 1 ) by means of the lower throat section (14) and the upper throat section (13) respectively. The fuel suction system (20), connected to the fuel depot (10), comprises a suction pipe (21 ) extending inside the main fuel tank (1 1 ), and a check valve (22) provided at the lower throat section (14). Said suction pipe (21 ) extends up to a suction point (23) determined on the base of the main fuel tank (1 1 ). Said check valve (22) comprises valve lips (221 ) provided at the lower throat section (14) in a manner extending from the auxiliary fuel tank (12) towards the main fuel tank (1 1 ). After filling the fuel depot (10), the agricultural vehicle can function. During the use of the vehicle on the field, in the field sections having a specific slope angle (x), the agricultural vehicle is moved with an angle which is identical to the slope angle (x). This provides the fuel depot (10) to be at a specific slope. The slope, occurring at the fuel depot (10), leads to passage of the fuel (30) between the main fuel tank (11 ) and the auxiliary fuel tank (12). Sometimes, this prevents suctioning of the fuel (30) by means of the suction pipe (21 ). By means of the check valve (22) system, continuous fuel (30) suction is provided despite the slope on the field. Check valve (22) is a mechanical valve providing single direction liquid or gas flow. Depending on the direction of the slope, the passage of the fuel (30) between the main fuel tank (1 1 ) and the auxiliary fuel tank (12) is adjusted by means of the check valve (22) placed at the lower throat section (14). In accordance with the rightward and leftward slope of the fuel depot (10), the check valve (22) is positioned such that the single direction fuel (30) flow, provided by the check valve (22), is from the auxiliary fuel tank (12) towards the main fuel tank (1 1 ). There is no flow from the main fuel tank (1 1 ) to the auxiliary fuel tank (12).
In case the fuel depot (10) is sloped rightwards, the check valve (22) allows fuel (30) flow from the auxiliary fuel tank (12) to the main fuel tank (1 1 ). The passage of the fuel (30) through the check valve (22) is provided by means of the fuel (30) flow continuing as the valve lips (221 ) are opened thanks to the pressure applied by the fuel (30) to said valve lips (221 ). In this case, since the main fuel depot (1 1 ) is full, the fuel (30) level does not remain under the suction point (23) and no problem is faced in the fuel suction system (20). In case the fuel depot (10) is sloped leftwards, the flow of fuel (30) from the main fuel tank (1 1 ) to the auxiliary fuel tank (12) is prevented by means of the check valve (22). The passage of the fuel (30) to the auxiliary fuel tank (12) results from the fact that the pressure, applied to the valve lips (221 ), is a pressure which is in opposite direction with respect to the pressure required for opening the valve lips (221 ). In this case, the fuel (30) stays in the main fuel tank (1 1 ) and since the fuel level is above the suction point (23), no problem is faced in the fuel suction system (20).
The valve lips (221 ) of the check valve (22) are made of rubber material. The rubber material contacts and adheres to the walls of the lower throat section (14), and sealing is provided by means of the hydrostatic pressure force formed at the valve lips (221 ). This prevents undesired fuel (30) passages between the main fuel tank (1 1 ) and the auxiliary fuel tank (12). Since the valve lips (22) are made of rubber, the check valve (22) is not affected by the dirt and residues which occur in the fuel (30) in time and which lead to accumulations in the fuel depot (10). Since the maintenance of the check valves (22) is easy, they provide advantage in terms of maintenance costs and they present long term usages.
During fuel (30) filling into the fuel depot (10), the fuel (30), filled through the filling inlet (17), reaches the check valve (22) and it opens the valve lips (221 ) and it enters into the main fuel tank (1 1 ). However, since the check valve (22) does not have cross sectional width which meets the fuel filling flow rate, the auxiliary fuel tank (12) is filled beforehand. Thanks to the embodiment of the upper throat section (13), this problem is prevented. As the auxiliary fuel depot (12) is filled thanks to the presence of the upper throat section (13), the fuel (30) also begins passing to the main fuel depot (1 1 ) through the upper throat section (13). Thus, there remains no need of extra waiting for completely filling the fuel depot (10).
The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
