4 to 7, the operation of the mission oil change apparatus 100 according to the present invention will be described. The preparation step ST-110, the circulation direction determination step ST-120, ST-130), and an oil exchange step (ST-140).

In the preparation step ST-110, the user first connects the ends of the first connection pipe 111 and the second connection pipe 112 to the second nipple 51 and the fourth nipple 61. At this time, the end of the first connection pipe 111 and the end of the second connection pipe 112 are connected regardless of the direction of the second nipple 51 or the fourth nipple 61.

In the following description, the end of the first connection pipe 111 is connected to the second nipple 51, and the end of the second connection pipe 112 is connected to the fourth nipple 61.

After the first connection pipe 111 and the second connection pipe 112 are connected to the mission 50 or the cooler 60, the vehicle is started. As shown in FIG. 4, the oil flows between the mission 50 and the cooler 60 when the vehicle is started. At this time, the oil can flow between the mission 50 and the cooler 60 through the first connection pipe 111, the second connection pipe 112, and the second pipe 117.

The first three way valve 113 and the second three way valve 114 are connected to the first connection pipe 111 and the second connection pipe 112 ) To the second tube (117).

The third three-way valve 119 is provided so that the flow path is directed to the fifth three-way valve 129 through the third pipe 118. At the same time, the fifth three-way valve 129 is provided to block the flow path leading from the third pipe 118 and to switch the flow path from the fifth pipe 122 to the third pipe 118 .

The fourth four-way valve 121 is provided so that the flow path is switched from the fourth pipe 120 to the fifth pipe 122.

Then, in the circulation direction determination step ST-120, when the power button of the input unit 127 of the mission oil change apparatus 100 is pressed, the mission oil change apparatus 100 controls the control unit C to operate the second three-way valve 114 to switch the flow path from the second connection pipe 112 to the first pipe 115.

When the second nipple 51 is a discharge part, the trough flows through the first connection pipe 111 and the second pipe 117 and then flows into the third pipe 118 connected to the second pipe 117, The flow is blocked by the fifth three way valve 129 and the pressure of the pressure gauge 116 is increased. Accordingly, the controller C, which receives the above-mentioned elevated pressure value information, determines the second nipple 51 of the mission 50 as the discharge unit.

As shown in FIG. 5, when the circulation direction (forward direction) of the mission oil is determined as described above, the valve operation step ST-130 is executed next. In the valve operating step ST-130, the flow path passes through the control unit C so that the direction of the first three-way valve 113 is changed from the first connecting pipe 111 to the second pipe 117 . At the same time, the controller C controls the direction of the second three-way valve 114 in the circulation direction determination step ST-120 so that the flow path is switched from the second connection pipe 112 to the first pipe 115 .

The control unit C also operates the third three-way valve 119 so that the flow path is switched from the third pipe 118 to the sixth pipe 126.

Way oil in the second pipe (117), and the third oil pipe (118) connected to the second pipe (117). The troughs flowing along the third pipe (118) flow to the third three-way valve (119). The trough that has flowed to the third three way valve 119 flows back to the sixth pipe 126 and is finally stored in the trough tank 130 connected to the end of the sixth pipe 126.

The new oil stored in the new oil tank 132 by the pump P operated in the oil change step ST-140 flows to the third pipe 118 connected to the new oil tank 132, And flows into the fifth five-way valve 129. The fresh oil flows again through the fifth pipe 122 and flows into the fourth four-way valve 121 by the fifth five-way valve 129. The fresh oil is again flowed to the fourth pipe 120 extending toward the first pipe 115 by the fourth four-way valve 121. The new oil flows to the first pipe 115 through the fourth pipe 120 and flows to the second three-way valve 114 connected to the other end of the first pipe 115. Finally, the fresh oil flowing from the second three way valve (114) through the second connection pipe (112) is supplied to the cooler (60).

In the circulation direction determining step ST-120, when the second nipple 51 is the inlet, the trough flowing in the second pipe 117 and the second connection pipe 112 flows into the first connection pipe 111, the pressure of the pressure gauge 116 is lowered. Accordingly, the controller C, which receives the lowered pressure value information, determines the second nipple 51 of the mission 50 as an inlet.

As shown in FIG. 6, when the circulation direction (reverse direction) of the mission oil is determined as described above, the valve operation step ST-130 is executed next. In the valve operating step ST-130, the flow path passes through the control unit C so that the direction of the second three-way valve 114 is changed from the second connecting pipe 112 to the second pipe 117 . At the same time, the controller C maintains the direction of the first three-way valve 113 so that the flow path is switched from the first connection pipe 111 to the first pipe 115.

The control unit C also operates the third three-way valve 119 so that the flow path is switched from the third pipe 118 to the sixth pipe 126.

In the oil change step ST-140, the controller C drives the motor M so that the pump P connected to the motor M is operated to supply the new oil from the new oil tank 132 have.

The oil flow path when the flow of the mission oil is reversed along the flow path of the mission oil formed by the plurality of three-way valves through the above-described operation steps will be described. First, The trough flows to the first three-way valve (113) through the second connection pipe (112) and the second pipe (117). The oil mist which is blocked by the first three-way valve (113) flows again through the third pipe (118) connected to the second pipe (117). The troughs flowing along the third pipe (118) flow to the third three-way valve (119). The trough that has flowed to the third three way valve 119 flows back to the sixth pipe 126 and is finally stored in the trough tank 130 connected to the end of the sixth pipe 126.

The new oil stored in the new oil tank 132 by the pump P operated in the oil change step ST-140 flows to the third pipe 118 connected to the new oil tank 132, And flows into the fifth five-way valve 129. The fresh oil flows again through the fifth pipe 122 and flows into the fourth four-way valve 121 by the fifth five-way valve 129. The fresh oil is again flowed to the fourth pipe 120 extending toward the first pipe 115 by the fourth four-way valve 121. The new oil flows to the first pipe 115 through the fourth pipe 120 and flows to the first three way valve 113 connected to one end of the first pipe 115.

The fifth three-way valve 129 is operated by the control unit C so that the flow path is switched from the third pipe 118 to the fifth pipe 122.

The fourth four way valve 121 is operated by the control unit C so that the flow path is switched to the fourth pipe 120 extending from the fifth pipe 122 toward the trough tank 130 .

Accordingly, when the pump P is operated after the valve operation is completed as described above, the oil remaining in the first connection pipe 111, the second connection pipe 112, and the second pipe 117 flows into the third (118) and sucked by the pump (P) toward the fifth three-way valve (129). The oil flowing through the fifth pipe 122 flows to the fourth pipe 120 connected to the trough tank 130 by the fourth three-way valve 121. The remaining oil in the tube through the fourth pipe 120 is stored in the trough tank 130.

As described above, the mission oil change apparatus 100 according to the present invention can reduce the work time for exchanging the mission oil because the confirmation of the discharge unit or the inlet unit is unnecessary, and the work efficiency of the worker can be improved.

Up to now, the mission oil change apparatus according to the present invention has been described with reference to the embodiments shown in the drawings, but it is merely an example, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible . Accordingly, the scope of the true technical protection should be determined by the technical idea of the appended claims.
