Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. As shown in FIG. 1, the valve assembly according to the first embodiment of the present invention includes a valve body 10 having a certain space or passage 10R therein. The valve body 10 is formed with a pair of entrance and exit ports 12, 14 through which fluids can enter and exit in mutually opposing directions.

The fluid in the inner passage 10R of the valve body 10 flows into the inlet and outlet ports 12 and 14 while the valve body 10 is maintained in the horizontal state, So that external fluid can be introduced into the interior through the outlets 12 and 14. [ A pair of opening and closing plates 16 and 18 are provided in the inner passage 10R of the valve body 10 in which the entrance and exit ports 12 and 14 are formed. The first open / close board 16 is for opening / closing the first entrance / exit 12, and the second open / close board 18 is for opening / closing the second entrance / exit 14.

In this embodiment, while the valve body 10 is in a horizontal state, the open / close boards 16 and 18 keep the openings 12 and 14 on both sides thereof open, It is possible to allow fluid to escape to the outside through the outlets 12 and 14 on both sides. In this case, the open / close plates 16 and 18 are hingedly connected to the upper end of the valve body 10, and the lower end thereof is installed in a free state. That is, the upper ends of the opening and closing plates 16, 18 are hingedly connected at the hinge points 16h, 18h on the inner surface of the valve body 10. [ Therefore, the upper ends of the opening / closing plates 16 and 18 are hinged to the inner surface of the valve body, so that they are always suspended vertically by their own weight.

In the illustrated embodiment, the pair of outlets 12 and 14 are respectively formed in the first inner wall 12A and the second inner wall 14A of the valve body 10, The second inner wall 14A is provided at a position facing each other, and the lower end is formed in an inclined state in a direction away from each other. Therefore, in a state in which the upper end portions of the open / close boards 16 and 18 are hinged to the inner side surface of the valve body 10, the open / close boards 16 and 18 maintain their vertical state due to their own weight as shown in FIG. The first doorway 12 and the second doorway 14 are opened.

The first opening and closing plate 16 and the second opening and closing plate 18 are formed on the first inner wall 12A and the second opening and closing plate 12A, 2 inner walls 14A, respectively, the entrances 12, 14 are clogged. In this specification, the entry / exit ports 12 and 14 are blocked because the opening / closing plates 16 and 18 are in close contact with the respective inner walls 12A and 14A in the valve body 10, . The fact that the ports 12 and 14 are closed indicates that the fluid can not flow to the connection portion through the inlet and the port in a clogged state in the internal space 10R of the valve body 10 . However, it should be noted that it is possible to send the fluid from the external connection portions 22, 24 to the internal space 10R even if the outlets 12, 14 are blocked.

Therefore, if the valve body 10 is kept in a horizontal state as shown in FIG. 1, all of the outlets 12 and 14 are open. Therefore, the air in the internal passages 10R of the valve body 10, It is also possible that the fluid outside the valve body 10 enters the internal passage 10R via the outlets 12 and 14. [

In the first embodiment of the present invention, as shown in Fig. 1, in the horizontal state of the valve body 10, the open / close boards 16 and 18 must be able to keep the openings 12 and 14 open will be. Since the upper ends of the open / close boards 16 and 18 are hinged to the inner side of the valve body 10 and the lower end thereof is in a free state, the position of the open / close boards 16 and 18 is always determined by its own weight. Accordingly, when the opening and closing plates 16 and 18 are formed in a plane as shown in the drawing, the opening and closing plates 16 and 18 are always kept in a vertical state in the horizontal state of the valve body 10, So that the entrance is always kept open.

1 to 5, the open / close plates 16 and 18 are formed of a material having a specific gravity higher than that of fluid flowing in and out of the inside of the valve body 10. That is, since the open / close plates 16 and 18 have a specific gravity higher than that of the fluid, when the upper end is hinged to the valve body 10, the lower end is supported in a vertical state. As will be described later, in the inclined state of the valve body 10, the opening and closing plates 16 and 18 open one of the outlets 12 and 14 by their own weight and close the other side. Here, the fact that one of the outlets 12 and 14 is closed means that the formed inner wall is in a vertical state (or a rotationally inclined state) so that the open / close plate can be in close contact with the inner wall. As described above, in the horizontal state of the valve body 10, the fluid can move from the inside to the outside or from the outside to the inside when the openings 12 and 14 are kept open at all times as described above.

In the illustrated embodiment, the first inner wall 12A and the second inner wall 14A are inclined in a predetermined direction so that the valve bodies 10 can maintain the openings 12, As shown in Fig. However, in the present embodiment, the pair of outlets 12 and 14 formed at the opposite positions in the horizontal state of the valve body 10 can keep the open state by the open / close boards 16 and 18, It is a matter of course that it can not be limited to the shape as in the embodiment shown in Fig.

Here, in the horizontal state of the valve body 10, the pair of entrance and exit ports 12, 14 formed at mutually facing positions can be kept open by the opening / closing plates 16, (Shape and position, etc.) between the shape and installation position of the open / close boards 16, 18 of the front and rear doors 16, 18 and the inner walls 12A, 14A and the openings 12, 14 opposed to each other. Further, it is a matter of course that a variety of designs of the inner walls 12A, 14A formed with the open / close boards 16, 18 and the entrance / exit openings 12, 14 are possible in the ordinary artisan.

The first outlet 12 is connected to the first fluid container 20 through a connection 22 and the second outlet 14 is connected to the second fluid container 30 through a connection 24, have. Thus, the flow of fluid through the valve body 10 described above may be, for example, the flow of fluid between the fluid containers 20,30. The connecting portions 22 and 24 may be formed in a bellows shape that is formed of a stretchable material or can be stretched or contracted in consideration of movement or rotation of the valve body 10. [

Next, the flow of the fluid according to the inclined direction and the inclined state of the valve body 10 will be described. In the embodiment as described above, since the entrance and exit ports 12 and 14 are all opened when the valve body 10 is in the horizontal state, the fluid in the internal passage 10R flows into the first connection portion 22 or the first connection portion 22, 2 connection 24 to the first fluid container 20 or the second fluid container 30. That is, the fluid inside the first fluid container 20 can flow to the second fluid container 30 through the valve body 10. Fluid flow in the opposite direction is also possible.

In FIG. 2, the left side of the valve body 10 is in a low inclined state. The first opening and closing plate 16 is in close contact with the first inner wall 12A and the second opening and closing plate 18 is further separated from the second inner wall 14A in the valve body 10, Respectively. It is a matter of course that the state of the open / close boards 16 and 18 is ultimately caused by the inclination of the valve body 10, and it can be said that the open / close boards 16 and 18 have a vertical state.

In this state, the fluid can not flow from the internal passage 10R to the first connection portion 22, and the fluid can flow only from the first connection portion 22 toward the internal passage 10R. Since the second doorway 14 is open, the fluid can flow from the internal passage 10R to the second connection portion 24. As shown in Fig. 2, it is possible to flow the fluid from the first fluid container 20 to the second fluid container 30, but the fluid can flow from the second fluid container 30 to the first fluid container 20 It is impossible to flow.

That is, in the embodiment as described above, when the valve body 10 is in the horizontal state as shown in FIG. 1, the fluid can flow to both sides, and when the valve body 10 is inclined It can be seen that the fluid is configured to flow from the fluid container 20 at a low position to the fluid container 30 at a high position.

Next, the embodiment shown in FIG. 3 and FIG. 4 will be described. The present embodiment is different from the first embodiment described above in the direction in which the first fluid container 20 and the second fluid container 30 are connected to the entrance and exit ports 12 and 14 of the valve body 10. The first fluid container 20 is connected to the opposite side entrance 14 of the valve body 10 and the second fluid container 30 is connected to the opposite side entrance 12 of the valve body 10 . Other configurations are substantially the same as those in Fig.

In the valve assembly of this embodiment, as shown in FIG. 4, when the left side of the valve body 10 is inclined at a low angle, the flow direction of the fluid is opposite to the above-described embodiment. That is, as shown in FIG. 4, the fluid can not flow from the internal passage 10R to the second connection portion 24A, and the fluid can flow only in the direction from the second connection portion 24A to the internal passage 10R. Since the second inlet / outlet 14 is open, the fluid can flow from the internal passage 10R to the first connection portion 22A.

4, it is possible to flow the fluid from the second fluid container 30 to the first fluid container 20, but the fluid can flow from the first fluid container 20 to the second fluid container 30, It can be seen that it is impossible to flow. 3, assuming that not only the valve body 10 but also the first fluid container 20 and the second fluid container 30 are inclined as a whole, It is possible to flow the fluid to the first fluid container 20 at a lower position in the first fluid container 30, but it is impossible to flow the fluid in the opposite direction.

3 and 4, when the valve body 10 is inclined, since the opening / closing plate 16 at a lower position is in close contact with the inner wall 12A, the inner space 10R It can be seen that the fluid can not flow to the entrance 12 at the lower position. Since the opening / closing plate 18 located at a higher position is further separated from the inner wall 14A while maintaining the vertical state, it can be seen that the fluid can flow from the inner space 10R to the entrance 14.

In the present invention, when the first fluid container 20 and the second fluid container 30 are formed of a stretchable material, the fluid container on the fluid receiving side may expand and become bulky. The larger the volume here, the higher the height can mean that it means. For example, if both the valve body 10 and the pair of fluid containers 20 and 30 are installed inside the sole of the shoe as described above, the fluid container 30 in the high position, 20). ≪ / RTI > If the first fluid container 20 and the second fluid container 30 are formed of a material having an elastic restoring force, they can be returned to the initial state in a neutral state (horizontal state of the valve body).

Therefore, when the second fluid container 30 is subjected to an external force (body weight of the shoe wearer), the fluid in the second fluid container 30 enters the first fluid container 20 through the valve body 10. Therefore, the volume of the first fluid container 20 is increased by the inflow of the fluid, for example, the height of the first fluid container 20 can be increased. When the height of the first fluid container 20 is increased and the height of the second fluid container 30 is lowered, the lower portion of the shoe sole with respect to the inclined ground surface becomes higher, . Therefore, it can be seen that when the slope is on the ground, the shoe can be corrected by the weight of the wearer so that the shoe can be brought close to the horizontal plane according to the height change of the fluid container of the shoe soles.

Thus, the external force that causes the fluid flow may be a separate force, which may be a force applied by a person directly to one of the fluid containers. In another embodiment, the external force that causes the flow of the fluid can be an electric driven pump, and the valve assembly of the present invention enables to control the flow direction of the fluid by itself by tilting in a desired direction have.

5 is a cross-sectional view taken along the line A-A in Fig. 1, illustrating a case where the fluid escapes from the internal passage 10R to the entrances 12, 14. It is not possible to exclude the possibility that the fluid flowing inside the internal passage 10R moves toward the entrance and exit ports 12 and 14 so as to press the opening and closing plates 16 and 18 and to move in the closing direction of the entrance and exit ports 12 and 14 . Of course, when the flow of the fluid is relatively slow, such a problem will not occur. However, when the flow is fast or the force applied to the mutually facing inner surfaces of the open / close boards 16, 18 is large, Can cause problems.

Therefore, as shown in Fig. 5, it is preferable that the flow of the fluid in the vicinity of the outlets 12 and 14 in the inside passage R is allowed to show a flow as indicated by an arrow. As shown in Fig. 1, when the openings 12 and 14 are open on both sides or when the second open / close board 18 is opened as shown in Figs. 2 and 4, the flow of the fluid toward the open / It is preferable to form the flow of the fluid so that the opening / closing plate does not move in the direction closing the door.

It is also possible to provide the fluid guides 32 and 34 so as not to generate fluid flow in the internal passage 10R as shown in the figure so as to press the opening and closing plates 16 and 18 toward the entrance and exit ports 12 and 14 . Alternatively, a path through which the fluid flows into the outlets 12 and 14 may be formed separately in the internal passage 10R so that the open / close plate is not affected by the flow of the fluid.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. The present embodiment corresponds to the case where the opening / closing plates 16A and 18A have a specific gravity lower than that of the fluid and have buoyancy in the fluid, contrary to the above-described embodiment. In the horizontal state of the valve body 10, So that the fluid can flow in all directions.

As shown in the drawing, the valve body 10 is formed with a pair of outlets 12 and 14 through which the fluid in the internal passage 10R enters and exits. A pair of opening and closing plates 16A and 18A is provided in the inner passage 10R of the valve body 10 in which the entrance and exit ports 12 and 14 are formed. The first open / close board 16A is for opening / closing the first entrance / exit 12, and the second open / close board 18A is for opening / closing the second entrance / exit 14. Here, the opening / closing plates 16A and 18A are formed of a material having a specific gravity lower than that of the fluid and buoyant in the fluid.

As shown in the figure, in the state in which the valve body 10 is horizontal, the open / close boards 16A and 18A are kept open at the entrance / exit openings 12 and 14 on both sides. The relationship between the first doorway 12 and the second doorway 14 and the first doorway board 16 and the second doorway board 18 in the valve body 10 of the present invention will now be described. In the same horizontal state, the open / close boards 16A and 18A are provided so that the openings 12 and 14 are kept open.

The opening and closing plates 16A and 18A are hingedly connected to the lower end of the valve body 10 and the upper end thereof is installed in a free state. That is, the lower end portions of the opening / closing plates 16A and 18A are hingedly connected to the lower hinge points 16H and 18H from the inner surface of the valve body 10. [ Therefore, the upper ends of the opening and closing plates 16A and 18A always float vertically about the lower end connected hinged to the inner surface of the valve body. In the illustrated embodiment, the pair of outlets 12 and 14 are respectively formed in the first inner wall 12A and the second inner wall 14A of the valve body 10, 2 inner wall 14A is formed in an inclined state in the direction in which the upper end portions are separated from each other.

The opening and closing plates 16A and 18A are sufficiently large enough to cover all the openings 12 and 14 so that when the opening and closing plates 16A and 18A are in close contact with the first and second inner walls 12A and 14A The entrance (12, 14) is clogged on the inside. In a state in which the lower end portions of the opening and closing plates 16A and 18A are hinged to the inner surface of the valve body 10, the opening and closing plates 16A and 18A are vertically floating as shown in the figure, In this state, the first doorway (12) and the second doorway (14) are opened.

6, if the valve body 10 is maintained in a horizontal state, the fluid can be discharged from the internal passage 10R of the valve body 10 through the outlets 12 and 14, It is also possible for fluid outside the valve body 10 to enter the internal passage 10R via the outlets 12 and 14. A pair of outlets 12A and 14A are formed in the inner inner walls 12A and 14A of the valve body 10 and the opening and closing plates 16A and 14A are formed in accordance with the inclined state of the inner inner walls 12A and 14A, , 18A) is configured to open the one-side entrance and close the other-side entrance.

7, when the valve body 10 is tilted in a state where the right side is tilted and the second inner wall 14A is in the vertical state or in the counterclockwise rotation state furthermore, the opening / closing plate 18A is moved in the second doorway (14). In this case, the fluid can not escape from the inside of the inner passage 10R through the second inlet / outlet 14, and only the fluid can enter the inner passage 10R through the second inlet / outlet 14. Therefore, in this state, the fluid can flow through the inner passage 10R only in the direction of the first fluid container 20 from the second fluid container 30. Here, if the second fluid container 30 is at a higher position than the first fluid container 20, the fluid can flow only in one direction from the fluid container 30 at a higher position to the fluid container 20 at a lower position to be. Also in the embodiment having such a buoyancy, it is natural that the connecting direction of the connecting portions 22 and 24 may be changed to be different from those in Figs.

6 and 7, a cover plate having buoyancy is used. In the horizontal state of the valve body, the first fluid container 20 is provided with the second fluid container 30, And in both directions from the second fluid container 30 to the first fluid container 20 side. It can be seen that the fluid can only flow in one direction from the high position fluid container to the low position fluid container when the valve body is inclined.

Hereinafter, the embodiment shown in FIG. 8 will be described. The present embodiment can be said to be for a valve assembly having a plurality of fluid containers. As shown in the figure, the valve assembly of this embodiment has one valve body 100, and the valve body 100 is connected to a plurality of (four) fluid containers. The fluid container of the present embodiment is composed of the fluid container FL on the front left side, the fluid container FR on the front right side, the fluid container RL on the rear left side, and the fluid container RR on the rear right side.

Four outlets (122, 124, 132, and 134) corresponding to the four fluid containers are formed inside the valve body 100, respectively. Opening and closing plates (142, 144, 152, 154) are installed in the respective outlets (122, 124, 132, 134). The function and installation conditions of the open / close plate in this embodiment will be described as follows. Basically, the opening and closing plates 142, 144, 152, and 154 of the valve body 100 are all kept open in the horizontal state, and one of the open / close plates opposed to each other in a tilted state is closed And the other side is open.

FIG. 8 shows the present embodiment through a plan view for convenience of explanation of the entire valve assembly. In addition, the valve assembly is maintained in a horizontal state, and all the open / close plates 142, 144, 152, 154 must be kept open. 1, the inner walls W1, W2, W3 and W4 of the valve body 100 on which the respective opening and closing plates 142, 144, 152 and 154 are provided are formed in an inclined state, Is hinged at its upper end and suspended vertically by its own weight.

Also in this embodiment, the opening and closing plates 142, 144, 152 and 154 may be formed of a buoyant material so that they are all opened in a horizontal state as shown in FIG. In the description of the present embodiment, the open / close plates 142, 144, 152, and 154 have a specific gravity higher than that of the fluid, and will be described with reference to an embodiment in which all the openings are opened in a horizontal state while being maintained in a vertical state by their own weight.

In the present embodiment, the slopes of the inner walls W1, W2, W3 and W4 are inclined in the direction in which the opposite lower ends thereof are away from each other. 8, the inner walls W1, W2, W3 and W4 formed with the outlets 122, 124, 132 and 134 in the plan view have inclined directions with respect to the front, back and left and right directions. That is, all the opening and closing plates 142, 144, 152, and 154 must react (open or close) to such inclination even if the valve body 100 is inclined in any direction.

For example, when viewed in a plan view, when one inner wall W1 is formed so as to follow the complete front-rear direction (the vertical direction in FIG. 8), the opening / closing plate 142 The door 122 is opened or closed. However, if the valve body 100 is inclined in the front-rear direction, the opening / closing plate 142 can not open or close the door 122. Therefore, each of the inner walls W1, W2, W3 and W4 having the entrance formed therein should be arranged in a diamond shape as shown in the plan view, and all the open / close boards 142, 144, 152 and 154 are arranged at the upper end of the entrance It shall be hinged and be able to be held vertically by its own weight. The inner wall of the valve body 100 has a rhombic shape (or a diamond shape). The inner walls W1, W2, W3 and W4 have a slope with respect to a straight line connecting the front and rear directions or a straight line in the left and right directions And it is preferable to have a slope of about 45 degrees.

However, in the present invention, it is apparent that the cross-sectional shape of the valve body can not be limited to the diamond shape described above. That is, in the horizontal plane (one plane), there are two directions, i.e., the front-rear direction and the horizontal direction, which are orthogonal to each other. Here, if the valve body is inclined at the same inclination angle with respect to both directions at the same time, the inner shape of the valve body is sufficient as long as each of the opening and closing plates can react with the composite inclination in the front and rear direction and in the left and right direction. For example, it is expected that the valve body having a circular cross section with respect to the horizontal plane in addition to the rhombus shape can sufficiently realize the present embodiment.

W2, W3, and W4 of the valve body 100 can be opened or closed at the same time, and at the same time, even in the case of tilting in the left and right direction, the opening / closing plates 142, 144, And the opening and closing plates 142, 144, 152, and 154, respectively. That is, in the present embodiment, the inner walls W1, W2, W3 and W4 of the valve body 100 and the opening and closing plates 142, 144, 152 and 154 are configured to be openable to at least any one of tilting in the left- .

In the horizontal state, as shown in Fig. 8, all the open / close boards 142, 144, 152, and 154 are kept in a vertical state, and all the outlets 122, 124, 132, and 134 are opened. Since the state in which the open / close board is opened in the plan view of FIG. 8 is not shown exactly, in order to explain the open / close state of all the open / close boards, the open / close state of the open / close board is illustrated in FIG. 8 to FIG. 10 by way of example.

The entrance ports 122, 124, 132 and 134 provided with the open / close plates 142, 144, 152 and 154 are connected to one fluid container FL, FR, RL and RR through connection portions FLC, FRC, RLC and RRC, respectively. In this embodiment, in order to allow the fluid to flow from a high position to a low position, each of the connecting portions FLC, FRC, RLC, and RRC is configured to connect the fluid container and the entrance port on the opposite sides to each other.

For example, the connecting portion FLC connects the fluid container FL on the front left side to the entrance 134 on the rear right side, and the connecting portion FRC connects the fluid container FR on the front right side and the outlet 132 on the rear left side ). By doing so, as shown in FIG. 4, the high-position entrance is opened, and the fluid can be discharged to the entrance at a high position in the internal space 110. In addition, the low-position entrance is closed, and the fluid can not be discharged to the connection portion through the entrance at the low position in the internal space 110.

9 shows a path through which the fluid can flow in a state where the left side of the valve body 100 is high. The left side of the valve body 100 means that the valve body 100 is inclined such that the left entrance 122 and the left entrance 132 are positioned higher than the right entrance 124 and 134. In this state, the open / close plates 142 and 152 of the left entry / exit openings 122 and 132 at the high position are opened as shown in FIG. The right and left opening and closing plates 144 and 154 are in close contact with the inner walls W2 and W3 at the inside of the valve body 100 and close the right entrance and exit ports 124 and 134, respectively.

When the left side of the valve body 100 is inclined at a higher position than the right side of the valve body 100, since the entrance ports 122 and 132 at the higher positions are opened, the fluid can flow from the internal space 110 to the connection portions RRC and FRC have. Since the low-position outlets 124 and 134 are blocked by the opening and closing plates 144 and 154, fluid can not flow from the internal space 110 to the connecting portions RLC and FLC, 110). ≪ / RTI >

Assuming that each fluid container has the same position as each of the outlets, when the left side of the valve body 100 is inclined to a higher position than the right side, the valve body 100 is lowered at a substantially high position in the fluid containers FL and RL It can be seen that the fluid can flow to the fluid containers FR and RR. When the fluid container according to the present embodiment is formed from an elastic material, the volume of the fluid containers FL and RL at the high position is small and the volume of the fluid containers FR and RR at the low position is large it means.

10 is a view showing a path through which the fluid can flow in a state where the front of the valve body 100 is high. It can be said that the front of the valve body 100 is high when the valve body 100 is inclined so that the front entrance and exit ports 122 and 124 are located higher than the rear entrance and exit ports 132 and 134. In this state, the opening / closing plates 142 and 144 of the front entrance / exit openings 122 and 124 located at the high position are separated from the inner walls W1 and W2 based on the principle as shown in FIG. 4, . The rear opening and closing plates 152 and 154 in the lower position are in close contact with the inner walls W3 and W4 inside the valve body 100 to close the rear entrance ports 132 and 134. [

When the front of the valve body 100 is inclined at a higher position than the rear of the valve body 100, fluid can flow to the connection portions RRC and RLC in the internal space 110 because the entrance portions 122 and 124 at the high position are opened. have. Since the low-level outlets 132 and 134 are blocked by the opening and closing plates 152 and 154, fluid can not flow into the connection portions FRC and FLC in the internal space 110, The fluid can not flow into the space 110.

Assuming that each fluid container has the same position (height) as the respective entrance, when the valve body 100 is inclined forward with respect to the rear, the front fluid containers FL, FR It can be seen that the fluid can flow to the fluid containers RL and RR in the lower position. Here, when each of the fluid containers is formed of a stretchable material, the volumes of the fluid containers FL and FR at the upper position are smaller and the volumes of the fluid containers RL and RR at the lower position are larger .

In this embodiment, the external force for flowing the fluid may be provided in various forms, for example, it is also possible to use a pump for generating the flow of the fluid. Or when each of the fluid containers is formed of a stretchable material as described above, an external force is applied to the fluid container at a high position (for example, a person steps on or applies pressure) . When the fluid container of the present invention is formed of a material having an elastic restoring force, the volume of the fluid container at a low position becomes large when the fluid container is inclined as described above. When the fluid container is restored to a horizontal state again, So that again all the fluid vessels can be restored to have the same volume.

In the embodiment shown in FIGS. 8 to 10, in order to allow the fluid to flow from the entrance at the higher position through the internal passage to the entrance at the lower position, the connection portion connects the fluid container and the doorway, . Conversely, if the connecting portion is configured to connect the fluid container adjacent to the fluid inlet and the fluid inlet, it is natural that the fluid can flow from the fluid inlet to the fluid outlet through the fluid passage at the lower position.

As in the present embodiment, when four outlets and four outlets are provided inside the valve body, there may occur a case where one outlets are relatively higher than three outlets. For example, And inclination in the left-right direction and a combination of the inclination in the left-right direction. In this case, referring to FIG. 8, the valve body 100 is inclined so that the front left entrance 122 is higher than the other three entrance 124, 132, and 134.

The front left doorway 122 has the highest position and the rear right doorway 134 has the lowest position. The entrance 124 of the front right side and the entrance 132 of the rear left side will be determined in accordance with the degree of inclination of the front and rear sides or the left and right sides. In this case, the opening / closing plate 154 at the lowest position completely closes the entrance 134, so that the flow of the fluid outwardly through the entrance 134 in the internal space 110 becomes impossible, Only the flow of the fluid into the internal space 110 is possible through the passage 134.

In this state, it is natural that the fluid can flow from the fluid container FL at the highest position to the fluid container RR at the lowest state. Since the opening and closing plates 144 and 152 for opening and closing the entrance ports 124 and 132 located at a medium height have a slight inclination, the openings 124 and 132 are opened and closed with a degree of opening and closing corresponding to the inclination. Accordingly, the corresponding fluid containers FR and RL may receive the fluid through the connection portions RLC and FRC and may transmit the fluid to the internal passage 110 through the connection portions RLC and FRC.

Here, the direction of the fluid can be determined by a force pushing the fluid, for example, the direction can be determined by an external force applied to each fluid container. Also in this embodiment, it is needless to say that the above-mentioned four opening / closing plates may be configured to have buoyancy, the lower end to be hinged and the upper end to be free.

In the embodiment as described above, it is possible to transmit the fluid from the fluid container at the higher position to the fluid container at the lower position, or to send the fluid from the fluid container at the lower position to the fluid container at the higher position, It can be seen that.

Next, another embodiment of the present invention shown in FIG. 11 will be described. In the embodiment described above, that is, in the embodiment shown in Figs. 1 to 7, when the valve body is in the horizontal state, both of the outlets at both sides are kept open so that the fluid is discharged from the first fluid container to the second fluid container And the fluid can flow from the second fluid container to the first fluid container.

However, the embodiment shown in FIG. 11 is configured such that the fluid can not flow in any direction when the valve body 10 is horizontal. The valve assembly of the present embodiment includes a valve body 10 having a certain space or passage 10R therein. The valve body 10 has a pair of The access openings 12 and 14 are formed.

The inlet and outlet ports 12 and 14 are formed on both side inner walls 12B and 14B of the valve body 10. The inner walls 12B and 14B of the present embodiment are formed as vertical walls. The upper and lower open / close plates 16 and 18 are hinged to the inside of the upper and lower portions of the door openings 12 and 14, respectively, and are formed of a material having a specific gravity higher than that of the fluid. Therefore, the open / close boards 16 and 18 are in close contact with the inner walls 12B and 14B on both sides of the open / close boards 16 and 18, .

Therefore, it can be seen that in the horizontal state of the valve body 10, the fluid can not move to the outside through the first inlet 12 or the second inlet 14 in the internal space 10R. As shown in the figure, the inner walls 12B and 14B are arranged in a vertical state in order to constitute the opening / closing plates 16 and 18 on both sides of the valve body 10 so as to block the entrance / . In addition, the inner walls 12B and 14B may be inclined so that the opening / closing plates 16 and 18 close the entrances 12 and 14 in the horizontal state of the valve body 10.

That is, as shown in FIG. 12, when the inner walls 12B and 14B of the opposite sides are inclined outward so that the upper ends thereof are further apart, the opening and closing plates 16 and 18 are closed by the inner walls 12B and 14B So as to close the respective outlets 12 and 14. 12, when the valve body 10 is inclined to one side, one opening / closing plate 16 or 18 opens only one opening 12 or 14, and at this time, the rotation of the valve body 10 It is a matter of course that the angle should be larger than the inclination angle of the inner walls 12B, 14B. Therefore, in order to form the inner walls 12B and 14B on both sides inclinedly, the inner walls 12B and 14B are formed so as to open the one door 12 or 14 in accordance with the inclination angle of the valve body 10, It is necessary to set the angle of inclination of the light emitting diode according to the application.

11 and 12, when the valve body 10 is inclined to one side, the opening / closing plate 16 or 18 on one side is brought into close contact with either one of the inner walls 12B or 14B Thereby blocking the entrance 12 or 14 at one side. The valve body 10 is inclined to the second fluid container 30 through the connecting portion 22, the valve body 10 and the connecting portion 24 in the first fluid container 20, It can be seen that the fluid can flow only to one side.

In this embodiment, the other structures and operations are the same as those of the other embodiments described above, so a detailed description will be omitted. For example, in the present embodiment, it is of course also possible to form the opening / closing plates 16 and 18 into a buoyant material. Also, in this embodiment, as shown in FIG. 3, it is also possible to configure the connecting portions 22 and 24 to connect the fluid container and the inlet and the outlet in opposite directions to each other.

It is needless to say that this embodiment can also be constituted such that four outlets are formed as shown in Fig. 8 and some of the outlets are opened and the other outlets are closed along the oblique direction of the valve body. The application of the present embodiment thus constitutes the valve body 10 so that the flow of the fluid is completely blocked when the valve body 10 is in the horizontal state and in the other inclined state, Quot; is applied as it is.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims. Of course.
