Description

Vehicle port and port-hose combination structure including the same {PORT FOR VEHICLE AND CONNECTING STRUCTURE FOR PORT AND HOSE}

The present invention relates to a vehicle port and a port-hose combination structure including the same.

In the case of eco-friendly vehicles such as electric vehicles (EV) or fuel cell vehicles (FCEV), it is common to use coolant to cool the components that make up the vehicle. Coolant is discharged from the component at certain times and supplied back to the component. However, in the case of eco-friendly vehicles, it is difficult to discharge all the coolant when discharging the coolant. This is because in the case of eco-friendly vehicles, the water head difference between components is generally low. This may cause unintentional leakage of remaining coolant during component repair or separation/replacement. This problem is more severe in electric buses where the battery room is provided in the upper roof.

Additionally, in the case of eco-friendly vehicles, there are many components that require cooling, and the amount of coolant required for each component may be different. To reflect this, it is not easy to properly distribute coolant and supply it to each component. This problem is even more evident in eco-friendly commercial vehicles.

Problems with coolant discharge/supply can also occur in regular vehicles, not eco-friendly vehicles.

The object of the present invention is to prevent unintentional leakage of coolant by allowing opening of the port only when discharge/supply of coolant is required, and not allowing opening of the port after discharge/supply, even with a simple structure. It provides a port and a port-hose combination structure including it.

In one example, the port-hose coupling structure between a port for discharging or supplying coolant for cooling components of a vehicle and a hose coupled to the port includes a port having an inlet and an outlet and a first flow passage communicating the inlet and the outlet. A body, provided on the port body, between a first position for closing the first flow path and a second position for opening the first flow path to a predetermined opening degree, a predetermined position perpendicular to the longitudinal direction of the first flow path. An opening/closing valve rotating about a reference direction, a hose body detachably coupled to the port body and having a second flow path communicating with the first flow path when coupled to the port body, and provided in the hose body; , While the hose body is coupled to the port body, it includes a pressing member that presses the on-off valve and rotates the on-off valve from the first position to a predetermined position between the first position and the second position. do.

In another example, a vehicle port for discharging or supplying coolant for cooling components of a vehicle includes a port body having a first flow path therein, and a port body provided in the port body, a first position closing the first flow path, and It includes an on-off valve that rotates between a second position that opens the first flow passage, and the on-off valve is provided on a hose coupled to the port body and presses the on-off valve when the port body and the hose are coupled. It is provided to be pressed by a pressing member and rotated from the first position to a predetermined position between the first position and the second position.

According to the present invention, in general cases where discharge/supply of coolant is not required, leakage of coolant can be prevented by closing the first passage of the port body through an on-off valve located at the first position, and discharge/supply of coolant. In this case, discharge/supply of coolant can be permitted simply by coupling the hose body provided with the pressurizing member to the port body.

In addition, according to the present invention, since the disk-shaped disk member provided in the on-off valve determines the opening and closing of the first flow path by rotation, the degree of rotation of the disk member is adjusted by the pressing member to adjust the amount of coolant supplied through the port/ Emissions can be controlled.

Hereinafter, some embodiments of the present invention will be described in detail through illustrative drawings. In adding reference numerals to components in each drawing, identical components are given the same reference numerals as much as possible even if they are shown in different drawings. Additionally, when describing embodiments of the present invention, if detailed descriptions of related known configurations or functions are determined to impede understanding of the embodiments of the present invention, the detailed descriptions will be omitted.

In the case of eco-friendly vehicles such as electric vehicles (EV) or fuel cell vehicles (FCEV), it is common to use coolant to cool the components that make up the vehicle. Coolant is discharged from the component in certain cases (for example, during vehicle maintenance, etc.) and supplied back to the component. The port-hose combination structure of the present invention is for discharging or supplying coolant to eco-friendly vehicles or general vehicles, and includes a port provided in a part of the vehicle through which coolant is discharged or supplied, and a port connected to the port. It includes a hose that guides the coolant discharged from the port to the outside or guides the coolant to the port.

The coupling structure of the present invention adopts a structure that allows opening of the port only when discharge/supply of coolant is required, and does not allow opening of the port after discharge/supply. For reference, the coolant may be water or an incompressible fluid.

The port-hose coupling structure according to an embodiment of the present invention will be described in detail with reference to FIG. 1 and the like. Figure 1 is an exploded perspective view of a port-hose coupling structure according to an embodiment of the present invention. As shown in FIG. 1, the port-hose coupling structure according to this embodiment includes a port body 110, an opening/closing valve 130, a hose body 150, and a pressing member 170.

Port body (110) and open/close valve (130)

With reference to FIGS. 2 and 3 , the port body 110 and the opening/closing valve 130 will be described in detail. Figure 2 is a perspective view showing the port body in which the on-off valve is installed in this embodiment, and Figure 3 is an exploded perspective view of Figure 2.

The port body 110 has an inlet 111 (see FIG. 1), an outlet 112 (see FIG. 1), and a first flow path 113 that communicates the inlet 111 and the outlet 112. As shown in FIG. 3, etc., the port body 110 may be formed in a tubular shape with a first flow path 113 formed therein. The vehicle's coolant may be discharged or supplied through the first flow path 113 of the port body 110.

The opening/closing valve 130 is provided to close or open the first flow path 113. To this end, the opening/closing valve 130 is provided to rotate between a first position that closes the first flow path 113 and a second position that opens the first flow path 113 to a predetermined opening degree.

The first position of the on-off valve 130 is shown in FIGS. 2 and 10, and the second position of the on-off valve 130 is shown in FIG. 21, etc. In a typical case, the opening/closing valve 130 is located in the first position to close the first passage 113. This prevents unintentional leakage of coolant. When discharge or supply of coolant is required, the open/close valve 130 is positioned in the second position to allow discharge/supply of coolant.

As will be described later, the opening/closing valve 130 is pressed by the pressing member 170 provided on the hose body 150 and rotates from the first position to the second position. Thereby, the coupling structure of this embodiment can prevent unintended leakage of coolant. The coupling structure of this embodiment positions the pressing member 170 in the second position only when discharge/supply of coolant is required, that is, when the hose body 150 is coupled to the port body 110, and coolant When discharge/supply is not required, that is, when the hose body 150 is separated from the port body 110, the pressing member 170 is placed in the first position.

The opening/closing valve 130 may be provided to rotate around a predetermined reference direction (see FIG. 1) perpendicular to the longitudinal direction (see FIG. 1) of the first flow path 113. The reference direction may be understood as the axial direction of the opening/closing valve 130.

The opening/closing valve 130 may include a disk member 131 (see FIG. 3 ) rotatably provided within the first flow path 113 to open and close the first flow path 113 . As shown in FIGS. 1 to 3 , the disk member 131 may be formed in a disk shape corresponding to the cross-sectional shape of the first flow path 113. If formed in this way, the first passage 113 may be closed when the disk member 131 is located in the first position. A sealing member may be provided on the edge of the disk member 131 to reduce the risk of leakage.

The opening/closing valve 130 may further include a shaft member 132 for rotation of the disk member 131. The shaft member 132 is formed to extend in the reference direction (see FIG. 1) as shown in FIGS. 1 to 3 in order to function as an axis for rotation of the disk member 131, and is connected to the port body 110 and the disk member. It can be connected to (131). Due to the shaft member 132, the disk member 131 can be provided in the first passage 113 to rotate about the reference direction. 1 to 3 show an example in which the shaft member 132 is formed integrally with the disk member 131, but the example of the shaft member is not limited to this.

The coupling structure of this embodiment may further include an elastic member (not shown) for restoring the disc member 131 to the first position when the pressure by the pressing member 170 is released. This will be explained with reference to Figure 3. If the disk member 131 is rotated clockwise by the pressing member 170, the elastic member is provided to rotate the shaft member 132 counterclockwise for counterclockwise rotation of the disk member 131. You can. For this purpose, the elastic member may consist, for example, of a leaf spring. As described above, the housing 133 may be provided at both ends of the shaft member 132, and the leaf spring has one end coupled to the housing 133 and the other end coupled to the shaft member 132 in the inner space of the housing 133. can be installed in Through this, the leaf spring can provide a restoring force to the shaft member 132 so that the shaft member 132 rotates in a predetermined direction. For reference, a protrusion (not shown) may be formed on the inner peripheral surface of the pot body 110 to prevent further rotation of the disk member 131 and stop the disk member 131 in the first position.

The opening/closing valve 130 is provided in the port body 110, and for this purpose, a bolt (A) and a boss (B) can be used as shown in FIGS. 1 to 3. For example, the shaft member 132 of the opening/closing valve 130 may be fixed to the port body 110 by a bolt (A). A boss (B) may be provided between the bolt (A) and the port body 110 to prevent coolant leakage.

Meanwhile, the port body 110 may include a first body 115 and a second body 116 coupled to the first body 115, as shown in FIGS. 2 and 3. As shown in FIG. 3, the first body 115 may be formed in the shape of a tube having a first internal space. The second body 116 may be formed in the shape of a tube having a second internal space that forms the first flow path 113 together with the first internal space when combined with the first body 115. The first internal space and the second internal space are opened at both ends, respectively, and communicate with the outside of the bodies 115 and 116. If the port body 110 is composed of two bodies 115 and 116 as above, it becomes easy to install the open/close valve 130 inside the port body 110.

In addition, the port body 110 may further include a first coupling hole 117 and a second coupling hole 118 that forms a predetermined hole together with the first coupling hole 117. As described in detail with reference to FIG. 3, the first coupling hole 117 penetrates the first body 115 in a direction corresponding to the reference direction (the direction of extension of the shaft member), but in the direction toward the second body 116 (Fig. It is formed to be open in the right direction of 3). And the second coupling hole 118 penetrates the second body 116 in a direction corresponding to the reference direction, and is formed to be open in a direction facing the first coupling hole 117 (left direction in FIG. 3). If the coupling holes 117 and 118 are provided in this way, a hole for the bolt A to pass through can be provided in the port body 110 after the first body 115 and the second body 116 are coupled.

Meanwhile, the first body 115 may be inserted into the second internal space of the second body 116 and coupled to the second body 116. At this time, in the section where the first and second bodies 115 and 116 overlap, a gasket 190 is provided between the outer peripheral surface of the first body 115 and the inner peripheral surface of the second body 116, as shown in FIGS. 1 to 3. More may be provided. The gasket 190 seals between the first and second bodies 115 and 116 to prevent leakage of coolant.

The gasket 190 may include a gasket body 191 and an insertion hole 192, as shown in FIG. 3. The gasket body 191 has a ring-shaped cross-section that is sandwiched between the outer peripheral surface of the first body 115 and the inner peripheral surface of the second body 116 and is oriented in a direction corresponding to the longitudinal direction of the first flow path 113 (see FIG. 1). It can be formed to extend. And the insertion hole 192 penetrates the gasket body 191 in a direction corresponding to the reference direction (the direction of extension of the shaft member), but in a direction corresponding to the longitudinal direction of the first flow path 113 (the right direction in FIG. 3). Although it is illustrated, the gasket body 191 is formed to open in the left direction (depending on the installation position of the gasket, it is also possible). The insertion hole 192 may serve as a hole for the bolt A to pass through when the gasket 190 is provided between the first and second bodies 115 and 116.

Hose body 150 and pressurizing member 170

The hose body 150 and the pressing member 170 will be described in detail with reference to FIGS. 4 to 8 . Figure 4 is a perspective view showing the hose body on which the pressing member is installed in this embodiment, Figure 5 is a perspective view showing the pressing member in this embodiment, and Figure 6 is a front view of Figure 5 (or the pressing member of Figure 5). Figure 7 is a cross-sectional view of the hose body of this embodiment, and Figure 8 is a cross-sectional view of Figure 4.

The hose body 150 is a hose having a second flow path 151 that communicates with the first flow path 113 when combined with the port body 110. The hose body 150 may be formed in a tubular shape with a second flow path 151, as shown in FIGS. 4 and 7 . The hose body 150 is detachably coupled to the port body 110. That is, it is coupled to the port body 110 to discharge/supply coolant, and is separated from the port body 110 when all of the coolant is discharged/supplied. For such coupling and separation, the end of the port body 110 may be provided with an annular protrusion 119 (see FIG. 11) that is elastically deformed inward when pressed. The hose body 150 may be a double pipe hose composed of two layers.

The pressing member 170 is provided on the hose body 150. And the pressing member 170 presses the disk member 131 of the opening/closing valve 130 while the hose body 150 is coupled to the port body 110 to move the disk member 131 in the first position, in the first position. It is provided to rotate to a predetermined position between the position and the second position.

The coupling structure of this embodiment can prevent leakage of coolant by closing the first passage 113 of the port body 110 through the opening/closing valve 130 located at the first position in normal times, and discharging/discharging the coolant. When supply is required, discharge/supply of coolant can be permitted simply by coupling the hose body 150 equipped with the pressing member 170 to the port body 110. Accordingly, the combination structure of this embodiment can very easily prevent coolant leakage and allow discharge/supply.

The pressing member 170 will be described in detail with reference to FIGS. 5 and 6 . The pressing member 170 may include a fixing part 171 and a pressing part 176. The fixing part 171 is a part of the pressing member 170 provided in the second flow path 151 to be fixed to the hose body 150. The pressing part 176 is a part for pressing the disk member 131 among the pressing members 170, and is a part that protrudes from the fixing part 171 toward the outside (left side in FIG. 4) of the hose body 150. am. The pressing part 176 presses the disk member 131 while the hose body 150 is coupled to the port body 110.

The hose body 150 will be described in detail with reference to FIGS. 7 and 8. A support part 155 and a connection part 156 may be provided in the second flow path 151 of the hose body 150. The support part 155 is a part for supporting the fixing part 171 of the pressing member 170 within the second flow path 151 of the hose body 150, and may be formed to surround the outer peripheral surface of the fixing part 171. there is. And the connection part 156 is a part for fixing the support part 155 within the second flow path 151 of the hose body 150, and protrudes inward from the inner peripheral surface of the hose body 150 to support the support part 155. It can be formed to be connected.

When the fixing part 171 and the support part 155 are configured as above, the pressing member 170 is inserted into the hose body 150 by inserting the pressing member 170 into the second flow path 151 of the hose body 150. ) can be combined. Additionally, the pressing member 170 can be coupled to or separated from the hose body 150 as needed.

Meanwhile, the fixing part 171 may be formed in the shape of a pipe extending in a direction corresponding to the longitudinal direction of the first flow path 113. Correspondingly, as shown in FIG. 8, the support part 155 may be formed in the shape of a tube extending in the longitudinal direction so as to tightly surround the outer peripheral surface of the fixing part 171. In this way, if the fixing part 171 and the support part 155 are formed in a tubular shape, the resistance generated by the above parts 155 and 171 during the flow of coolant can be minimized.

Return to FIGS. 5 and 6 to take a closer look at the pressing member 170. When the tubular port body 110 extending in the longitudinal direction (see FIG. 1) is projected in the longitudinal direction, the first flow path 113 is defined as a first region (Ⅰ) with the reference direction (referring to the extension direction of the shaft member) as the boundary. and a second area (II) (see FIGS. 2 and 11). The pressing part 176 may be provided to press a portion of the disk member 131 located in the first region (I) at the first position (see FIG. 11). When the pressing member 170 is configured in this way, rotation of the disc member 131 can be induced by first pressing a predetermined part of the disc member 131 (the lower part of the disc member in FIG. 11) through the press part 176. In addition, it is possible to provide a space (see III in FIG. 11) in which the remaining portion of the disk member 131 (the upper part of the disk member in FIG. 11) rotates without interference.

Meanwhile, in order to describe the pressing member 170 of the present embodiment in more detail, the hose body 150 moves from the right to the left of the port body 110 in a direction corresponding to the longitudinal direction, as shown in FIGS. 9 and 10, and moves to the port body 110. Assuming that it is coupled to (110), a virtual pipe (P) is assumed as shown in FIG. 6. When the virtual pipe P shown in FIG. 6 is projected in the reference direction (see FIG. 1, the paper direction of FIG. 6), it has an upper boundary line (Lt) extending in the longitudinal direction, and an upper boundary line (Lt) It appears as a lower boundary line (Lb) that is spaced downward from and extends in the longitudinal direction.

When assuming the above virtual pipe (P), the pressing member 170 has the shape of the portion of the virtual pipe (P) located to the right of the reference line with respect to FIG. 6 (ultimately the shape of FIG. 5). can be formed. Here, the reference line is a line that appears as a continuation of the first to third lines (L1, L2, L3) when the virtual pipe (P) is projected in the reference direction, and the first line (L1) is the lower boundary line (Lb). The second line (L2) is a line extending from the upper end of the first line (L1) to the right, and the third line (L3) is a line to the right of the second line (L2). It is a line extending from the end to the top. At this time, the upper and right sides include both straight and inclined directions.

Among the reference lines, the first line L1 may be defined to extend upward and right from the left end of the lower boundary line Lb. When the pressing member 170 is defined based on the first line L1, as shown in FIG. 11, the pressing member 170 is located at the lower end of the disk member 131 (i.e., the furthest away from the shaft member). Since the portion where there is) is pressed first, the disk member 131 can be rotated more smoothly.

Among the reference lines, the third line L3 includes a vertical portion L4 extending upward from the right end of the second line L2, and an inclined portion L5 extending upward to the right from the upper end of the vertical portion L4. It may also be defined to include. When the pressing member 170 is defined based on the third line L3, as shown in FIG. 12, etc., while the disc member 131 rotates due to pressure by the pressing member 170, the disc member 131 There may be no interference by the pressing member 170.

As shown in FIGS. 5 and 6, the pressing member 170 of this embodiment has a first inclined surface 177 corresponding to the first line L1 and a surface corresponding to the second line L2, which are formed substantially horizontally. It may include a horizontal surface 179 and a second inclined surface 172 corresponding to the inclined portion L5 of the third line L3. At this time, the first inclined surface 177 and the horizontal surface 179 may be connected by a curved portion 178.

Meanwhile, as shown in FIGS. 6 and 11, the pressing part 176 of the pressing member 170 is located at a portion defined by the first line L1 and the second line L2 (i.e., the first part of the virtual pipe). and a portion located on the right side of the second line) and may be located in the first area (I). And the fixing part 171 of the pressing member 170 may be a part defined by the third line L3 on the right side of the pressing part 176, and the first and second areas on the right side of the pressing part 176. It can be located in (Ⅰ, Ⅱ).

Operation of the coupling structure according to this embodiment

The operation of the coupling structure according to this embodiment will be described with reference to FIGS. 9 to 23.

As shown in FIG. 9, the port body 110 is provided at a portion (C) of the vehicle components where discharge/supply of coolant is required.

The hose body 150 is inserted into the port body 110 as shown in FIGS. 9 to 11 when discharge/supply of coolant is required. Since the pressing member 170 provided in the hose body 150 has a first inclined surface 177, as the hose body 150 moves, the pressing member 170 is positioned at the lowermost part of the disk member 131. is contacted first. As a result, the portion that is farther away from the center of rotation is pressed first, so the disk member 131 can rotate smoothly. In addition, since the pressing part 176 of the pressing member 170 is located only in the first region (I), interference occurs between the disc member 131 and the pressing member 170 during rotation of the disc member 131. An empty space (III, see FIG. 11) may be provided to prevent this from occurring.

As the movement of the hose body 150 continues, the pressing member 170 moves the disk member 131 to the curved portion 178 between the first inclined surface 177 and the horizontal surface 179, as shown in FIGS. 12 and 13. It becomes pressurized. As the hose body 150 moves, the disk member 131 continues to rotate, and as a result, the opening degree (opening degree rate) of the first flow path 113 gradually increases.

During rotation of the disk member 131, interference between the disk member 131 and the pressing member 170 may be a problem. If the pressing member 170 is formed so that the length of the pressing part 176 located in the first area (I) (the left and right lengths of the pressing part in FIG. 11) is longer, the empty space (III) is sufficiently secured and The same interference problem may not occur. Alternatively, as shown in FIG. 12 , if the second inclined surface 172 is formed on the pressing member 170, interference problems may not occur even if the pressing part 176 is relatively short. Since the disk member 131 is circular, in the case of FIG. 13, there is a high possibility that an interference problem with the disk member 131 will occur at the uppermost part of the second inclined surface 172. If the second inclined surface 172 is formed to be inclined, the first 2 Since the uppermost part of the inclined surface 172 is located away from the disk member 131, the possibility of interference problems occurring can be reduced.

If the movement of the hose body 150 continues, the disk member 131 may be rotated to be positioned almost horizontally, as shown in FIGS. 14 to 23. When rotated to this state, resistance due to the disk member 131 during the flow of coolant can be minimized.

Meanwhile, as shown in FIG. 6, the fixing part 171 has a fixing hole that is recessed away from the vertical portion (L4) on the right side of the vertical portion (L4) of the third line (L3) and opens toward the vertical portion (L4). (174) (see Figure 5). When the disk member 131 is positioned almost horizontally due to pressure by the pressing member 170, the portions adjacent to both ends of the disk member 131 derived based on the extending direction of the shaft member 132 are fixed holes 174. ) can be inserted into. With this insertion, the opening degree of the disk member 131 can be kept constant while the port body 110 and the hose body 150 are coupled.

When discharge of the coolant is completed, the hose body 150 is separated from the port body 110. As a result, when the pressure by the pressing member 170 is released, the disk member 131 returns to the first position by the elastic member. As a result, the first flow path 113 is closed again.

For reference, Figures 12 and 13, Figures 14 and 15, Figures 16 and 17, Figures 18 to 20, and Figures 21 to 23 are diagrams showing the same state, respectively.

Meanwhile, the degree of insertion of the hose body 150 into the port body 110 can be determined by the following.

First, by appropriately selecting the position of the connection part 156, the degree of insertion of the hose body 150 can be determined. As shown in FIG. 11, the right end of the port body 110 comes close to the connection part 156 as the hose body 150 is inserted. If the distance from the inlet of the hose body 150 to the connection part 156 is appropriately selected, the right end of the port body 110 may be caught in the connection part 156, thereby preventing further movement of the hose body 150. there is.

Second, the step 175 (see FIGS. 5 and 23, etc.) where the shaft member 132 (the housing can also be seen as a part of the shaft member extending from the shaft member) is placed at an appropriate position on the horizontal surface 179 of the pressing member 170. ), the degree of insertion of the hose body 150 can be determined. As shown in FIG. 23, when a step 175 is formed at an appropriate position on the horizontal surface 179 of the pressing member 170, the shaft member 132 of the opening/closing valve 130 is caught by the step 175 and the hose body 150 ) may be prevented from further movement. For reference, some components (eg, bolts or bosses) are not shown in FIGS. 20 and 23 to explain the above content.

Control of discharge/supply flow rate by pressurizing member 170

The disc member 131 is rotated by the pressing member 170, and the opening degree (opening degree rate) of the first flow path 113 is determined depending on the degree of rotation of the disc member 131. Therefore, when the degree of rotation of the disk member 131 changes at the time of final coupling between the port body 110 and the hose body 150, the opening degree of the first flow path 113 also changes, and thus the discharge/supply flow rate of the coolant may also vary. there is.

The degree of rotation of the disc member 131 may be determined by the distance between the initial contact position and the final contact position between the pressing member 170 and the disc member 131. For example, when comparing Case 1 and Case 2 below, it can be seen that the disk member 131 rotated more in Case 2 than in Case 1.

case 1

11 is the initial contact state between the pressing member 170 and the disk member 131, and the state in FIG. 12 is the final contact state between the pressing member 170 and the disk member 131.

case 2

11 is the initial contact state between the pressing member 170 and the disk member 131, and the state in FIG. 14 is the final contact state between the pressing member 170 and the disk member 131.

Considering the above, it will be understood that the degree of rotation of the disk member 131 varies depending on the length of the pressing part 176 from the fixing part 171. Using this, the combined structure of this embodiment can be utilized so that the discharge/supply flow rates of the coolant are different from each other. For example, by selectively using any one of several pressing members having pressing parts 176 of different lengths, the disk member 131 is rotated from the first position to the second position, or the disk member 131 is moved from the first position to the first position. It can be rotated to a predetermined position between the first position and the second position. That is, if the hose body 150 is provided so that any one of the plurality of pressing members 170 having different pressing parts 176 of different lengths protruding from the fixing part 171 can be selectively attached or detached, it can be attached to the components of the vehicle. It becomes possible to adjust the discharge/supply flow rate differently depending on the condition.

For example, it may be desirable to adjust discharge/supply flow rates differently depending on the vehicle's components. In this case, after preparing several press members 170 with different lengths of the press part 176, a long press member 170 is added to the port body 110 provided in the component requiring a large discharge/supply flow rate. ), and a short pressurizing member 170 can be used in the port body 110 provided in components requiring a small discharge/supply flow rate. As seen above, the pressing member 170 can be detachably coupled to the hose body 150, so in this embodiment, the pressing member 170 of different specifications can be properly coupled to several hose bodies 150 of the same standard. You can use the combination structure in the example.

Alternatively, the above flow rate can be adjusted by adjusting the position of the step 175 described with reference to FIG. 23. For example, if the step 175 in FIG. 23 is located close to the left end of the pressing part 176, the insertion degree of the hose body 160/pressure member 170 will be shortened, and the step 175 will increase the pressure. Positioning away from the left end of part 176 will increase the degree of insertion of hose body 160/pressure member 170. Therefore, even if the length of the pressing part 176 is the same, by preparing a plurality of pressing members 170 with different positions of the steps 175 and selectively combining them with the hose body 150, discharge/discharging is performed depending on the components of the vehicle. It becomes possible to adjust the supply flow rate differently.

For reference, by changing a part of the shape of the pressing member 170, the degree of rotation of the disk member 131 can be adjusted when fastening the port body 110 and the hose body 150, and thereby the flow rate can also be adjusted. . For example, if the shape of the pressing member 170 is changed so that the a, b, and c values in FIG. 24 are changed, the disk member 131 is the final shape when the port body 110 and the hose body 150 are coupled. The degree of rotation can vary, and as a result, the opening rate is changed, making it possible to control the flow rate. Figure 24 is a diagram for explaining flow rate control by changing the shape of the pressing member.
