This invention relates to a fuel oil supplying apparatus for tank lorry, more particularly, to such a fuel oil supplying apparatus that is provided with a deaerator comprizing an air-separation hose joined to one end of a feeding hose in a suddenly reduced fashion, or with an deaerator disposed to a deaeration tank having an fuel oil surface detecting sensor at the top wall thereof, for separating air from the fuel oil, and then enabling the positive amount of the fuel oil to be supplied at the time of oil supplying.
Generally, on a tank lorry for transporting the fuel oil, a fuel oil supplying (or oiling) apparatus is mounted, and the supplied amount of the oil is intended to be designated cumulatively using the apparatus at the time of oiling.
Thus, said apparatus should be not only manufactured as smaller as can be mounted on a vehicle, but also operated -- 2l5l9lg to supply the oil positively by the driving power taken off from the vehicle-owned power only.
However, in the convention oiling apparatus mounted on the general tank lorry, the power for driving a pump (50) is taken off from the transmission mechanism of the vehicle, and is then transmitted or cut off mechanically by using the mechanical clutch mechanism, so that the structure of the apparatus is to be complicated and the cost becomes to be so much higher to be mounted thereon.
Said pump (50) is designed that the upstream end thereof is connected to another deaerator (51) that is further leaded to a feeding hose through which the fuel oil is supplied from the oil tank which is not shown, while the downstream end thereof is connected said deaerator (51) and an oil flow meter (53) via an air tank for deaeration respectively.
Therefore, the air is intended to be released through an air vent (51a) provided at the top wall of said deaerator (51), so that some amount of the oil may be released together with the vented air occasionally and said air vent (51a) is shut off by a float (51c) with the function of the buoyant force of the oil (51b) after all the air have been released.
-- Zlsl9l9 This means that the entire structure of said deaerator is complicated.
Therefore, when the oiling is performed by using an oil gun connected to the oil flow meter (53) with the fuel oil supplying apparatus to which the conventional deaerator (51) is employed, the positive oiling is not always achieved and the oiling itself becomes to be troublesome due to the residual air contained in the air, despite the presence of said deaerator (51).
Thus, this invention is to eliminate such drawbacks and disadvantages as mentioned above, of which the primary object is to provide a fuel oil supplying apparatus for tank lorry, which is characterized in that said apparatus employs an oil pump using an electromagnetic clutch, and said apparatus is driven by a DC motor which is easily controllable, and said apparatus which is provided with a deaerator comprizing an air-separation hose joined to one end of a feeding hose in a suddenly reduced fashion, or with an deaerator disposed to a deaeration tank having an fuel oil surface detecting sensor at the top wall thereof, for separating air from the fuel oil, and then enabling the positive amount of the fuel oil to be supplied at the time of oil supplying, so that said apparatus becomes to be not only constructed as small as can be mounted on a vehicle due to its simpler structure, but also operated to supply '- 2l5l9l9 the positive amount of the oil cumulatively due to the complete deaeration from the oil (gasoline or diesel oil) under the controller at the time of oiling.
In order to accomplish the above object, a fuel oil supplying apparatus for tank lorry of this invention, wherein an oil pump (11) having an electromagnetic clutch for pressurized-feeding the (gasoline or diesel) oil from an oil tank (23) is connected to the oil tank (23) via a dearator (21) at the upstream end thereof and connected to an oil flow meter (7) at the downstream end thereof respectively, is characterized in that said deaerator (21) comprizes a gasoline separation valve (16) and a solenoid gasoline valve (17) and a solenoid diesel oil valve (15), in a bifurcated manner, and comprizes an air-separation hose (4) having a smaller diameter connected to one end of a feeding hose (lb) in a suddenly reduced fashion, in order to separate the air from the oil at the time of oiling.

Referring to Fig. 2, the schematic diagram of one embodiment of a deaerator of a fuel oil supplying apparatus for tank lorry according to the present invention is illustrated. In this Figure, an oil pump (11) adapted in the fuel oil supplying apparatus for tank lorry according to the present invention is the oil pump using an electromagnetic clutch for attaining the pressurized oil feeding from a fuel oil tank (23), which is disclosed in the specification of "Oil Pumping Apparatus" (Korea Utility Model Application Number 93-1502) which is also devised by the present inventor, wherein said oil pump (11) is connected to a gasoline and diesel oil tank (23) and an oil flow meter (7) respectively via a deaerator (21) which has a simple structure.
And, said oil pump (11) is drived by a DC motor (10) through a coupling (8).
In Figs. 3 and 4, the deaerator (21) for separating the air from the fuel oil (for example, gasoline or diesel oil) being fed through a feeding hose (1) comprizes a gasoline separation valve (16) and a solenoid gasoline valve (14), and a diesel oil separation valve (17) and a solenoid diesel oil valve (15) in a bifurcation manner, which are operated under the control and regulation of a controller not shown, wherein, an an-separation hose (4) having a ~15191~

As said auxiliary A valve (3) becomes to be closed when the supplied amount of the oil is as less as 4 liter than the predetermined target amount for supplying at the time of oiling, a reduction feeding hose (2) is cut off and is then communicated to a feeding hose (lc) via the auxiliary B valve (13).
At this time, the diameter of said reduction feeding hose (2), for example 25 mm, becomes to be a smaller one, for example 3.2 mm, than that of the feeding hose (1), and the operation of the same hose becomes to be activate by the operations of said auxiliary B valve (13) and auxiliary A valve which are in contrarily operational relationship there between.
An oil pressure-operated switch (5) shown in Fig. 3 is provided at the lower part of the deaerator (21) so as to ._ 2lsl9l9 be activated by the rise of the inner pressure within the feeding hose (1), of which pressure is intended to be increased in case that the oil gun (not shown) is slipped from the operators hand or the oiling is interrupted during the time of oiling.
An oil pressure-operated switch (5) shown in Fig. 3 is provided at the lower part of the deaerator (21) so as to be activated by the rise of the inner pressure of the feeding hose (1), of which pressure is intended to be increased in case that the user do not grasp the oil gun or suddenly interrupt the oiling during the time of oil supplying. And, there are provided an outlet port to the oil flow meter, to which the oil gun is intended to be connected, a power supply (9) to said DC motor (10), and an inlet port (20) to said feeding hose (la), respectively.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be particularly described as follows, with reference to the preferred embodiments illustrated in the accompanying drawings.

Referring to Fig. 2, the schematic diagram of one embodiment of a deaerator of a fuel oil supplying apparatus for tank lorry according to the present invention is illustrated. In this Figure, an oil pump (11) adapted in the fuel oil supplying apparatus for tank lorry according to the present invention is the oil pump using an electromagnetic clutch for attaining the pressurized oil feeding from a fuel oil tank (23), which is disclosed in the specification of "Oil Pumping Apparatus" (Korea Utility Model Application Number 93-1502) which is also devised by the present inventor, wherein said oil pump (11) is connected to a gasoline and diesel oil tank (23) and an oil flow meter (7) respectively via a deaerator (21) which has a simple structure.
And, said oil pump (11) is drived by a DC motor (10) through a coupling (8).
In Figs. 3 and 4, the deaerator (21) for separating the air from the fuel oil (for example, gasoline or diesel oil) being fed through a feeding hose (1) comprizes a gasoline separation valve (16) and a solenoid gasoline valve (14), and a diesel oil separation valve (17) and a solenoid diesel oil valve (15) in a bifurcation manner, which are operated under the control and regulation of a controller not shown, wherein, an an-separation hose (4) having a ~15191~
smaller diameter (for example, 3.2 mm) is joined to an one end of a feeding hose (lb) having a larger diameter (for example, 2.5 mm) in a suddenly reduced fashion, so that the air may be easily separated from the fuel oil, and the separated air is them returned to the gasoline or diesel-oil tank (23) through the solenoid gasoline valve (14) or the solenoid diesel-oil valve (15) selectively.
In the operation of such deaerator (21) constructed as mentioned above, as the air-separation hose (4) having a smaller diameter is joined to the one end of the feeding hose (lb) having a larger diameter in a suddenly reduced fashion, the flow of the fuel oil supplied from the oil pump (11) is trapped by the end of the feeding hose (lb) having a larger diameter and only the air contained in the oil can be escaped through the air separation hose (4) having a smaller diameter during the time of the oiling through an oil gun which is not shown via the oil flow meter.
Thus, the air escaped through said air separation hose (4) is returned to the gasoline or diesel-oil tank (23) via the gasoline separation valve (16) and solenoid gasoline valve (14), or the diesel oil separation valve (17) and solenoid diesel oil valve (15) which has been selected by the controller previously, while the deaerated oil mentioned above becomes to be fed to the oil gun which is 21519Ig not shown through the feeding hose (1) shown in Fig. 3 via the oil flow meter (7) and the encoder (12).
On the other hand, the oil at the time of interruption of oiling is bypassed to a bypass hose (18) via a bypass valve (6) shown in Figs. 3 and 4, and is then returned to the feeding hose (la), while said bypass valve (6) is operated contrarily to an auxiliary A valve (3) of said feeding hose (lb).
As said auxiliary A valve (3) becomes to be closed when the supplied amount of the oil is as less as 4 liter than the predetermined target amount for supplying at the time of oiling, a reduction feeding hose (2) is cut off and is then communicated to a feeding hose (lc) via the auxiliary B valve (13).
At this time, the diameter of said reduction feeding hose (2), for example 25 mm, becomes to be a smaller one, for example 3.2 mm, than that of the feeding hose (1), and the operation of the same hose becomes to be activate by the operations of said auxiliary B valve (13) and auxiliary A valve which are in contrarily operational relationship there between.
An oil pressure-operated switch (5) shown in Fig. 3 is provided at the lower part of the deaerator (21) so as to ._ 2lsl9l9 be activated by the rise of the inner pressure within the feeding hose (1), of which pressure is intended to be increased in case that the oil gun (not shown) is slipped from the operators hand or the oiling is interrupted during the time of oiling.
An oil pressure-operated switch (5) shown in Fig. 3 is provided at the lower part of the deaerator (21) so as to be activated by the rise of the inner pressure of the feeding hose (1), of which pressure is intended to be increased in case that the user do not grasp the oil gun or suddenly interrupt the oiling during the time of oil supplying. And, there are provided an outlet port to the oil flow meter, to which the oil gun is intended to be connected, a power supply (9) to said DC motor (10), and an inlet port (20) to said feeding hose (la), respectively.
The operation of the fuel oil supplying apparatus for tank lorry according to the present invention as constructed as mentioned above will be described hereinafter with reference to Figs. 3 and 4.
At first, the user may select the desired kind of fuel oil (gasoline or diesel oil) in the oil tank (23; see Fig.
2) by setting up the oil selection key on the controller of the oil supplying system, and input the amount of oil to supply, and then pull down-the oil gun which is connected 2l5l9l~
to the outlet port (19) of the oil flow meter (7).
Then, the oil pump (11) is operated, with the DC motor (10) energized by the power supplied from the power supplying (9), whereby the oil in said oil tank (23) is introduced into the oil pump (11) through the inlet port (20), and pressurized by the passage through the oil pump, and then fed at high pressure state through the feeding hose (lb, lc, 1) sequentially.
Therefore, the oil in said oil tank (20) is introduced into the oil pump (11) through the inlet port (20) along the feeding hose (la), and pressured by the pump.
The pressurized oil is fed to the outlet port (19) to which the oil gun is connected, which is not shown, via the feeding hose (lb, lc, 1), the encoder (12) which counts the amount of the oil, and the oil flow meter (7).
At this time, the oil supplied through said oil pump (11) is primarily deaerated within the outlet hose (lb) during the time of oiling as shown in Fig. 2.
Such separated air is re-deaerated through the gasoline separation valve (16) and solenoid gasoline valve (14), or the diesel oil separation valve (17) and solenoid diesel oil valve (15) at the deaerator (21) depending on the \-- 21~1919 selected oil (gasoline or diesel oil), and is returned to the gasoline or diesel oil tank (23) through the air separation hose (4).
Therefore, with the oil supplying apparatus according to the invention, as the air is completely separated from the oil by the deaerator (21), during the time of oiling, the positive amount of oil can be supplied thereby.
When the supplied amount of oil is as less as 4 liter than the target amount during the normal oiling, the auxiliary A valve (3) is closed and the other auxiliary B
valve (13) is opened by the controller which is not shown, so that the amount of the oil passed through the feeding hose (lb) becomes to be decreased as it flows the reduction feeding hose (2) of smaller diameter, whereby the smaller amount of oil is supplied along the feeding hose (lc).
Thus, the rest amount of oil becomes to be gradually supplied through said feeding hose (lc) via the encoder (12), the oil flow meter and the outlet port (19) of the oil gun, and when the total amount of supplied oil reaches the predetermined one, the DC motor will be stopped to rotate by the controller which is not shown, so that the operation of the oil pump (11) will be ceased, thereby terminating the oil supplying moderately.
~ 2lsl9l9 On the other hand, if the oil gun is not grasped or the operation of the oil gun is interrupted suddenly during the time of oil supplying, the oil passed through the oil pump (11) is then pressurized to rise the pressure within the feeding hose (1), so that the oil pressure-operated switch (5) is activated due to the increased oil pressure.
With the operating of the oil pressure-operated switch (5), the bypass valve (6) which is bifurcatedly disposed to the feed hose (lb) is opened to bypass the pressurized oil to the feeding hose (la) through the bypass hose (18), thereby preventing the feed hose (1) from being damaged by the rised pressure due to the sudden interruption of the oil supplying.
Fig. 5 illustrates another embodiment of a deaerator of a fuel oil supplying apparatus for tank lorry according to the present inventor, wherein the aerator is differ from that of the apparatus shown in Fig. 2 in such respect that a deaerator (21') is disposed to the deaeration tank (21a) having an fuel oil surface detecting sensor (30) at the top wall thereof in stead of the deaerator (21), and a pressure balance (32) is disposed to an oil outlet port (25), and an air separator hose (4) is disposed on a solenoid gasoline valve (14) and a solenoid diesel oil valve (15), so that the separated air from the oil supplied from an oil pump (11) is re-deaerated precisely to return a gasoline or -- 2l5l9lg diesel oil tank (23).
And, the electromagnetic clutch is employed to said oil pump (11), which is connected to the oil tank (23)through an inlet port (20), and is connected to a DC motor (10) through a coupling (8), and is connected to an outlet port (19) through an oil feeding port (25) respectively, thereby supplying the oil through said outlet port (19) of the oil gun.
Figs. 6 and 7 show a fuel oil supplying apparatus for tank lorry according to the present invention, wherein the deaerator shown in Fig. 5 is employed, wherein the oil tank (23) connected to the inlet port (20) is divided into a diesel-oil tank (23') and a gasoline tank (23") by a partition plate, in which diesel oil and gasoline are stored isolatedly as shown in Fig. 8, and discharging ports (23b) (23c) disposed in the lower part of the oil tank (23) are, via oil selection solenoid valves (24) (24'), joined together and connected to an inlet part of the oil pump (11) employing the elector magnetic clutch for pressurized-feeding the diesel oil or gasoline.
The oil pump (11) is connected to the DC motor (10) via coupling (8) by which the driving power is transmitted, and the deaerator (21') for separating the air from the selected oil which flows in the feeding hose (1) is `- 2151gl~
connected to the outlet part of said oil pump (11) and a bypass valve (6) is also connected to the outlet part thereof in order to reduce the oil pressure when the oil pressure at the downstream end thereof is increased beyond the predetermined valve and the inlet and outlet parts are inter-connected by a bypass hose (18).
At the downstream end of the deaerator (21') shown in Fig. 5, connected are a pressure balance (32) for regulating the pressure in an oil feeding hose (27a) to which the deaerator (21') and the oil gun (27) shown in Fig. 8 are connected, and the auxiliary A valve (3) which becomes to be closed when the oil supplying is interrupted suddenly or the supplied amount is reached to the predetermined one.
The outlet part (3b) is also connected to the inlet part (3a) by the reduction feeding hose (2) as a bypass pipe via an auxiliary B valve (13).
At the downstream end of said auxiliary A valve (3), connected sequentially are a check valve (26) shown in Fig.
8 for preventing the oil metered by the oil flow meter (7) from counterflowing to the deaerator (21') during the oiling, a pressure balancer (32b) for preventing the pressure rise in the feeding hose (27a), and a pressure sensor (28).
