Summary of the invention

For example, in a valve device disclosed in Patent Literature 1, a tubular element that defines a flow path is fixed to a housing. In the case of the tubular element, a fixing part is fixed to the housing with a fastening element. It should be noted that when the tubular element is fastened to the housing with the fastening element, a crack can occur on the housing side. In this case, cooling water can escape from the crack in the housing.

It is an object of the present disclosure to provide a valve device that is capable of suppressing leakage or leakage of cooling water due to possible attachment of the tubular member to the housing.

The present disclosure relates to a valve device configured to control cooling water in a heating element of a vehicle. The valve device comprises a housing, a valve, a pipe or line element and a pipe fastening element.

The pipe fastening element is guided through a pipe-side fastening hole and screwed into a housing-side fastening hole, in order to thereby fix a pipe-side fixing part to a housing-side fixing part.

The housing-side fixing part defines a gap between the housing-side fixing part and an outer wall of a housing main body.

Accordingly, when the pipe member is fastened to the housing with the fastening member, the configuration enables to suppress a crack from expanding toward the housing main body even though the crack occurs in the housing-side fixing part. This configuration makes it possible to suppress the leakage of the cooling water caused by the attachment of the pipe member to the housing.

The ECU 8th controls the operation of the engine 71 and controls the rotational position of the valve body 31 , causing the cooling water through the device 7 is conducted to the heat exchange in the device 7 perform. Accordingly, it is possible to cool the engine oil and the EGR gas to improve the fuel consumption. It is also possible to pass the cooling water through the heater 6 to conduct heat exchange between the air in the vehicle 1 and the cooling water. Accordingly, it is possible to change the interior of the vehicle 1 to warm up.

7 is a graph showing the relationship between the rotational position (horizontal axis) of the valve body 31 and the open / closed state (vertical axis) of the valve body openings 430 . 420 and 410 , that is, the relationship of the overlap areas between the valve body openings 430 . 420 and 410 and the respective seal openings 360 , shows. It should be noted that the areas of overlap between the valve body openings 430 . 420 and 410 and the respective seal openings 360 the Flow path areas to the device 7 , to the heater 6 and to the cooler 5 correspond.

The ECU 8th selects a “normal mode” that is used when there is a request to pass the cooling water through the heater 6 exists (heater request) or a "heater shutdown mode" used when there is no heater request and rotates the valve body 31 , The "normal mode" and the "heater shutdown mode" separate an area (area d) when all valve body openings 430 . 420 and 410 with the outer peripheral wall of the valve body 31 are closed (all closed: see 3 ), and the flow rate of the cooling water to the device 7 , to the heater 6 and to the cooler 5 is zero. In area d is the cooling water flow to the device 7 , to the heater 6 and to the cooler 5 blocked.

In "normal mode" the water supply to the heater has 6 the highest priority. If in 7 the valve body 31 is rotated in a direction projecting from the region d to the right, the rotational position of the valve body moves 31 towards an area adjacent to area d (area c). The valve body opening begins in area c 420 open and the cooling water starts through the heater 6 to pour. If the valve body 31 is rotated further, the valve body opening 420 fully open, and the rotational position of the valve body 31 moves to an area adjacent to area c (area b). The valve body opening begins in area b 430 open, and the cooling water starts through the device 7 to pour. If the valve body 31 is rotated further, the valve body opening 430 fully open, and the rotational position of the valve body 31 moves to an area adjacent to area b (area a). The valve body opening begins in area a 410 open, and the cooling water starts through the cooler 5 to pour. Upon further rotation of the valve body 31 becomes the valve body opening 410 fully open (fully open condition). It should be noted that the rotational position of the valve body 31 , at which the valve body opening 410 is fully open, the rotational limit of the valve body 31 equivalent. At this time, the first convex regulatory element stands 332 with the regulatory part 631 in contact (see 6 ).

In "heater shutdown mode" the water supply becomes the heater 6 not done. The priority of the water flow towards the device 7 is higher than the water flow to the cooler 5 , If in 7 the valve body 31 is rotated in a direction projecting from the region d to the left, the rotational position of the valve body moves 31 towards an area adjacent to area d (area e). The valve body opening begins in area e 430 open, and the cooling water starts through the device 7 to pour. If the valve body 31 is rotated further, the valve body opening 430 fully open, and the rotational position of the valve body 31 moves to an area adjacent to area e (area f). In area f there is only the valve body opening 430 opened, and the cooling water only flows through the device 7 , If the valve body 31 is rotated further, the rotational position of the valve body moves 31 towards an area adjacent to area f (area g). The valve body opening begins in area g 410 open, and the cooling water starts through the cooler 5 to pour. Upon further rotation of the valve body 31 becomes the valve body opening 410 fully open. The ECU 8th can be done by rotating the valve body 31 based on the "normal mode" and the "heater shutdown mode" as in 7 shown to achieve both fuel consumption and air conditioning performance.

As described above, the drive member 70 the gear part 72 on that is the driving force of the engine 71 on the wave 32 can transmit. Furthermore, the valve device 10 further with the holding element 73 provided that the snap lock part 731 has that on the drive part cover 80 is clickable and the motor 71 and the gear part 72 between the holding element 73 and the drive part cover 80 holds.

Accordingly, it is possible to use the engine 71 and the gear part 72 on the side of the separation part 60 to mount while the engine 71 and the gear part 72 in the drive part cover 80 being held. It is also possible to reduce the number of parts.

As in 3 is shown, the separation part 60 a separation through hole 65 from the shaft insertion hole 62 extends outward and at the outer wall of the partition part main body 61 is open. Furthermore, the housing 20th a case through hole 270 on, which is from the inner wall of the housing opening 210 extends outward and at the outer wall of the housing main body 21 is opened, and that is formed so that this with the separation through hole 65 can be associated.

Accordingly, it is possible to remove the cooling water from the interior 200 through the shaft insertion hole 62 towards the side of the drive part 70 flows to the separation through hole 65 respectively. This configuration enables the flow of cooling water in the interior 200 towards the side of the drive part 70 to suppress. Note that this is to the separation through hole 65 flowing cooling water from the case through hole 270 is released to the outside.

In the present embodiment, the case through hole is 270 on the mounting surface 201 open. That is, if the valve device 10 at the machine 2 is attached, the housing through hole 270 with the machine 2 covered.

Accordingly, it is possible to prevent foreign water from entering through the housing through hole 270 and the separation through hole 65 inside the valve device 10 to suppress.

The motor 71 is provided such that the motor shaft 711 perpendicular to the mounting surface 201 stands and the worm wheel 712 towards the opposite side to the mounting surface 201 points.

Accordingly, it is possible to reduce the gearbox height and the external structure of the drive part 70 to reduce.

Because the engine main body 710 of the motor 71 near the machine 2 (Mounting surface 201 ) can be provided, it is also possible to increase the vibration resistance of the engine 71 to improve. In addition, it is possible to improve the robustness compared to a separation, because of the motor 71 acting vibration is reduced.

(Third embodiment)

20th shows a part of the valve device according to a third embodiment.

In the third embodiment, the arrangement of the ball valves differs 41 . 42 . 43 , the cylindrical connecting part 44 and the cylindrical valve connecting part 45 of the valve housing 31 in the wave 32 from that in the first embodiment. As in 20th shown is the ball valve 41 , the cylindrical connecting part 44 , the ball valve 42 , the cylindrical valve connecting part 45 and the ball valve 43 in this order from the drive part side 70 towards the opposite side to the drive part 70 in the direction of the axis of rotation Axr1 arranged.

With the ball valves 41 . 42 and 43 of the valve body 31 At least a part of the outer circumferential wall is spherical, and at least a part of the inner circumferential wall is designed such that it is recessed to the outside.

As described above, the present embodiment relates to the valve device 10 , which is configured so that the cooling water in the machine 2 of the vehicle 1 controls. The valve device 10 is with the housing 20th , the valve 30th and the valve seal 36 Mistake.

The housing 20th has connections ( 220 . 221 . 222 and 223 ) on the interior 200 connect to the outside.

The valve 30th has the valve body 31 that in the interior 200 about the axis of rotation Axr1 is rotatable, the inside of the valve body 31 trained valve body flow path 300 , the valve body openings ( 410 . 420 and 430 ) the valve body flow path 300 with the outside of the valve body 31 connect, and that on the axis of rotation Axr1 intended shaft 32 , The valve 30th is configured to communicate the state of communication between the valve body flow path 300 and the connections ( 220 . 221 . 222 and 223 ) via the valve body openings ( 410 . 420 and 430 ) with the rotational position of the valve body 31 changes.

The valve seal 36 is ring-shaped and at positions corresponding to the connections ( 220 . 221 . 222 and 223 ) provided to against the outer peripheral wall of the valve body 31 to come across. The seal opening 360 with the valve body openings ( 410 . 420 and 430 ) according to the rotational position of the valve body 31 can be associated is within the valve seal 36 educated. The valve seal 36 is configured to be between the valve gasket 36 and the outer peripheral wall of the valve body 31 seals fluid-tight.

In the valve body 31 At least a part of the outer circumferential wall is spherical, and at least a part of the inner circumferential wall is designed such that it is recessed to the outside.

Accordingly, it is possible to control the shape of the spherical surface of the outer peripheral wall of the valve body 31 to improve. This configuration makes it possible for the cooling water to leak or leak from the outer peripheral wall of the valve body 31 to suppress.

It is also possible to change the flow path area of the valve body flow path 300 to increase and reduce the water pipe resistance.

The ball valves 41 . 42 and 43 of the valve body 31 are designed so that at least a part of the inner circumferential wall is spherical.

Accordingly, it is possible to change the thickness in at least part of the valve body 31 to be uniform. This configuration enables the accuracy of the spherical surface of the outer peripheral wall of the valve body 31 further improve and the flow path area of the valve body flow path 300 to enlarge further.

With the ball valves 41 . 42 and 43 is the distance between the inner peripheral wall and the outer peripheral wall within a range of at least a part of the direction of the axis of rotation Axr1 and equal to the circumferential direction. That is, the inner peripheral wall and the outer peripheral wall of the ball valves 41 . 42 and 43 are formed in a spherical shape with the same curvature in the range described above. That is, the valve body 31 is designed in such a way that the thickness is uniform or uniform at least in the region described above (uniform thickness).

Accordingly, it is possible to change the thickness in at least part of the valve body 31 to make it even. This configuration enables the accuracy of the spherical surface of the outer peripheral wall of the valve body 31 further improve and the flow path area of the valve body flow path 300 to enlarge further.

With the ball valves 41 . 42 and 43 of the valve body 31 is the distance between the inner peripheral wall and the outer peripheral wall in a region of at least the seal opening 360 in the direction of the axis of rotation Axr1 and corresponds to the circumferential direction.

Accordingly, it is possible to change the thickness of the valve body 31 to be even within the area. This configuration enables the accuracy of the spherical surface of the outer peripheral wall of the valve body 31 further improve and the tightness of the valve seal 36 to improve.

If with the ball valves 41 . 42 and 43 of the valve body 31 all seal openings 360 with the outer peripheral wall of the valve body 31 are covered and are in a completely closed state, the distance between the inner peripheral wall and the outer peripheral wall in the area corresponds to at least the seal opening 360 in the direction of the axis of rotation Axr1 and equal to the circumferential direction.

Accordingly, it is possible to ensure the tightness of the valve seal 36 to improve further in the fully closed state.

The wave 32 is integral with the valve body through insert molding 31 intended.

Accordingly, it is possible to control the valve body 31 to improve.

It is also possible to increase the number of assembly steps of the shaft 32 to reduce.

The valve body 31 has the first part of the body 33 and the second part of the body 34 that in the virtual level Vp 1 including the axis of rotation Axr1 are divided into two. The first part of the body 33 and the second part of the body 34 are at respective connection surfaces 331 and 341 connected.

Accordingly, it is possible to use the valve body 31 by die slide injection (DSI), as described later, with high accuracy.

As in 20th and 23 is shown, the first partial body 33 the first convex regulatory element 332 on, which is from the surface on the side of the separation part 60 towards the side of the regulation recess 63 extends with one end in the regulatory recess 63 positioned (with regard to the regulatory recess 63 , please refer 3 and 6 ). The second part of the body 34 exhibits the second convex regulatory element 342 on, which is from the surface on the side of the separation part 60 towards the side of the regulation recess 63 extends with one end in the regulatory recess 63 is positioned.

Accordingly, it is possible to rotate the valve body 31 by pushing the first convex regulatory element 332 and the second convex regulatory element 342 against the regulatory part 631 the regulatory recess 63 to regulate. It should be noted that the first convex regulatory element 332 and the second convex regulatory element 342 accordingly in the first partial body 33 and the second partial body 34 are formed so that it is possible to separate (exfoliate) the first partial body 33 and the second part of the body 34 at the connecting surfaces 331 and 341 to suppress when the first convex regulatory element 332 and the second convex regulatory element 342 with the regulatory part 631 the regulatory recess 63 get in touch.

The first convex regulatory element 332 extends along the interface 331 towards the side of the regulatory recess 63 , The second convex regulatory element 342 extends along the interface 331 towards the side of the regulatory recess 63 while this against the first convex regulatory element 332 bumps.

Accordingly, it is possible to separate the first partial body 33 and the second part of the body 34 at the connecting surfaces 331 and 341 effectively suppress when the first convex regulatory element 332 and the second convex regulatory element 342 with the regulatory part 631 the regulatory recess 63 get in touch.

As in 20th . 21 and 22 is shown, the valve body 31 a valve body opening rib 411 on the inside edge of the Valve body opening 410 connects. The valve body 31 has valve body opening ribs 421 and 422 on the inside edge of the valve body opening 420 connect. The valve body 31 has valve body opening ribs 431 and 432 to the inside edge of the valve body opening 430 connect to. Accordingly, it is possible to increase the strength of the valve body openings 410 . 420 and 430 to improve.

The valve body opening ribs 411 . 421 and 431 are formed on the virtual plane, which is the axis Axs1 the wave 32 (Axis of rotation Axr1 ) includes, that is, on the virtual level Vp1 which the connecting surfaces 331 and 341 includes. That is, the valve body opening ribs 411 . 421 and 431 are designed so that these are the connecting surfaces 331 and 341 record between them. The valve body opening ribs 422 and 432 are formed on the virtual plane, which is the axis Axs1 the wave 32 (Axis of rotation Axr1 ) includes and orthogonal to the virtual plane Vp1 lies.

As in 24 and 25th is shown is the valve body opening rib 411 at a position away from the virtual spherical surface Vs1 along the outer peripheral wall of the ball valve 41 of the valve body 31 formed radially inwards.

It is correspondingly when the valve body rotates 31 possible to increase the sliding resistance by locking the valve body opening rib 411 trapped valve seal 36 to suppress.

As in 24 and 25th is shown is the valve body opening rib 411 in an arc shape by a predetermined distance from the virtual spherical surface Vs1 trained remotely. Note that the valve body opening ribs 421 and 422 and the valve body opening ribs 431 and 432 in an arc shape along the outer peripheral wall of the ball valves 42 and 43 are formed from the virtual spherical surface by a predetermined distance.

Accordingly, it is possible to increase the sliding resistance when the valve body rotates 31 suppress and the flow path area within the valve body opening ribs 411 . 421 . 422 . 431 and 432 to enlarge.

As in 26 the connection surfaces are shown 331 and 341 at positions from the valve seal 36 removed when all seal openings 360 all valve seals 36 with the outer peripheral wall of the valve body 31 covered and in a fully closed condition.

It is correspondingly with a step that the outer peripheral wall at the connecting surfaces 331 and 341 of the valve body 31 can be formed, leakage of the cooling water from the position between the valve seal 36 and the outer peripheral wall of the valve body 31 suppress when the valve body 31 in the fully closed state.

As in 20th is shown, the valve body 31 a part 441 with a specific shape on the connecting surfaces 331 and 341 with the cylindrical connecting part 44 is formed and has an outer wall with a curvature that is different from the curvature of the outer peripheral wall of the cylindrical connecting part 44 differs. The valve body 31 has a part 451 with a specific shape on the connecting surfaces 331 and 341 in the cylindrical valve connecting part 45 is formed and has an outer wall with a curvature which is different from the curvature of the outer peripheral wall of the cylindrical valve connecting part 45 differs.

Accordingly, when the valve body rotates, it slides 31 the parts 441 and 451 with specific shape as well as the valve seal 36 Not. The configuration allows malfunctions of the valve body 31 to suppress and abrasion of the valve seal 36 to suppress.

With the respective parts 441 and 451 with a specific shape, the outer wall is formed such that it extends from the outer peripheral wall of the cylindrical connecting part 44 and the cylindrical valve connecting part 45 protrudes outwards.

With the respective parts 441 and 451 with a specific shape, the outer wall may be formed so as to extend from the outer peripheral wall of the cylindrical connecting part 44 and the cylindrical valve connecting part 45 to be exempt from within.

With the respective parts 441 and 451 With a specific shape, the outer wall can be planar.

As in 22 is shown, the valve body 31 an end surface opening 415 that at an end surface of the ball valve 41 in the direction of the axis of rotation Axr1 is trained to the space 400 between valves, that between the ball valve 41 and the ball valve 42 is formed with the valve body flow path 300 of the ball valve 41 to connect, and an end surface opening 425 that at an end surface of the ball valve 42 in the direction of the axis of rotation Axr1 is trained to the space 400 between valves with the Valve body flow path 300 of the ball valve 42 to connect, on the radially outer side of the cylindrical connecting part 44 , Note that the end surface openings 415 and 425 corresponding to a "first end surface opening" and a "second end surface opening".

The inlet port 220 (please refer 3 ) communicates with the room 400 between valves. Accordingly, this can be done from the inlet port 220 in the interior 200 flowing cooling water over the room 400 between valves, the end surface openings 415 and 425 in the valve body flow path 300 stream.

The space 400 between valves is opened over the entire area in the circumferential direction. Accordingly, it is possible to determine the water pipe resistance of the cooling water coming from the inlet connection 220 in the interior 200 flows and toward the valve body flow path 300 flows to reduce.

As in 27 shown is the wave 32 through insert shapes in the cylindrical connecting part 44 integral with the valve body 31 educated. That is, the wave 32 is with the cylindrical connector 44 welded, but not to other parts of the valve body 31 than the cylindrical connector 44 ,

If in the valve body flow path 300 an insert molding with the shaft 32 is provided, the flow path area of the valve body flow path 300 small, and therefore there is a risk of an increase in water pipe resistance. Since in the present embodiment the insert molding with the shaft 32 with the cylindrical connecting part 44 outside the valve body flow path 300 is provided, it is possible to reduce the water pipe resistance.

As in 27 is shown shows the shaft 32 a rotation stop element 321 on which the relative rotation with respect to the cylindrical connecting part 44 can regulate. The rotation stop element 321 is designed so that it has a polygonal cross-sectional shape. In the present embodiment, the rotation stopper is 321 formed so that it has a hexagonal cross-sectional shape. It should be noted that the rotation stop element 321 is formed by the outer peripheral wall of, for example, the columnar shaft 32 with six positions in the circumferential direction is removed flat. The outer wall of the rotation stop element is corresponding 321 on the radially inner side of the outer peripheral wall of the shaft 32 positioned. It should be noted that the inner wall of the cylindrical connecting part 44 is designed so that it has a hexagonal cross-sectional shape that the shape of the rotation stop element 321 equivalent.

Accordingly, it is possible to adjust the relative rotation between the valve body 31 and the wave 32 to regulate with a simple configuration.

As in 28 is shown, the valve body 31 the cylindrical valve connecting part 45 with the ball valve 42 on the the cylindrical connecting part 44 opposite side with respect to the ball valve 42 is connected, and in which the outer peripheral wall and the inner peripheral wall are cylindrical and the valve body flow path 300 is formed inside, and a ball valve 43 that with the cylindrical valve connector 45 on the the ball valve 42 opposite side with respect to the cylindrical valve connecting part 45 is connected, and in which the outer peripheral wall is formed in a spherical shape.

With the cylindrical valve connecting part 45 the outer peripheral wall and the inner peripheral wall are cylindrical. Accordingly, it is possible to change the flow path area of the inner valve body flow path 300 ensure.

As in 20th is shown, the outer diameter of the outer peripheral wall of the ball valve 41 equal to the outer diameter of the outer peripheral wall of the ball valve 43 , It should be noted that the outer diameter of the outer peripheral wall of the ball valve 42 also equal to the outer diameter of the outer peripheral wall of the ball valve 41 and the outer diameter of the outer peripheral wall of the ball valve 43 is.

The area of a first outermost end surface 301 as an end surface of the ball valve 41 on the the ball valve 43 opposite side in the direction of the axis of rotation Axr1 differs from the area of a second outermost end surface 302 as an end surface of the ball valve 43 on the the ball valve 41 opposite side in the direction of the axis of rotation Axr1 , Note that the area of the second outermost end surface 302 is larger than the area of the first outermost end surface 301 , The length of the ball valve is corresponding 43 in the direction of the axis of rotation Axr1 shorter than the length of the ball valve 41 ,

Accordingly, it is possible to change the size of the valve body 31 to reduce in the axial direction and the external structure of the valve device 10 to reduce.

As in 20th and 22 is shown, the valve body 31 the Valve body opening rib 422 , which is the inner edge of the valve body opening 420 of the ball valve 42 connects, and the valve body opening rib 432 , which is the inner edge of the valve body opening 430 of the ball valve 43 connects. Note that the valve body opening rib 422 and the valve body opening rib 432 corresponding to a “second valve body opening rib” and a “third valve body opening rib”.

The valve body opening rib 422 and the valve body opening rib 432 are at the same position in the circumferential direction of the valve body 31 educated. That is, the valve body opening ribs 422 and 432 are designed so that they are in a direction parallel to the axis of rotation Axr1 are arranged. It should be noted that the valve body opening rib 411 and the valve body opening rib 421 at the same position in the circumferential direction of the valve body 31 are trained.

Accordingly, it is possible to control the turbulence of the ribs around the valve body opening 422 and 432 suppressing flowing cooling water and reducing the water resistance.

As in 20th . 21 and 22 is shown, the valve body 31 End surface opening ribs 416 and 417 that the cylindrical connecting part 44 with the ball valve 41 over the end surface opening 415 connect, and end surface opening ribs 426 and 427 that the cylindrical connector 44 with the ball valve 42 over the end surface opening 425 connect. Note that the end surface opening ribs 416 and 417 corresponding to the "first end surface opening rib" and the end surface opening ribs 426 and 427 correspond to the "second end surface opening".

Two end surface opening ribs each 416 and 426 are designed so that the cylindrical connecting part 44 record between them. Two end surface opening ribs each 417 and 427 are designed so that the cylindrical connecting part 44 record between them.

Note that the end surface opening ribs 416 and 426 on the virtual level Vp1 are trained. That is, the end surface opening ribs 416 and 426 are designed so that these are the connecting surfaces 331 and 341 record between them. The valve body opening ribs are corresponding 411 and 421 and the end surface opening ribs 416 and 426 at the same position in the circumferential direction of the valve body 31 educated.

As in 20th and 22 are the end surface opening rib 417 , the end surface opening rib 427 , the valve body opening rib 422 and the valve body opening rib 432 at the same position in the circumferential direction of the valve body 31 educated. That is, the end surface opening ribs 417 and 427 and the valve body opening ribs 422 and 432 are designed so that they are in a direction parallel to the axis of rotation Axr1 are arranged. Note that the end surface opening ribs 417 and 427 and the valve body opening ribs 422 and 432 are formed on a virtual plane, which is the axis Axs1 the wave 32 (Axis of rotation Axr1 ) includes and orthogonal to the virtual plane Vp1 lies.

Accordingly, it is possible to control the turbulence around the end surface opening ribs 417 and 427 and the valve body opening ribs 422 and 432 suppressing flowing cooling water and reducing the water resistance.

As in 20th . 21 and 22 is shown form the end surface opening ribs 416 and 417 a fin end surface gap 418 between the end surface opening ribs 416 and 417 and the end surface of the ball valve 41 in the direction of the axis of rotation Axr1 , The end surface opening ribs 426 and 427 form a fin end surface gap 428 between the end surface opening ribs 426 and 427 and the end surface of the ball valve 42 in the direction of the axis of rotation Axr1 , Note that the end surface opening rib 418 a "first fin end surface gap" and the fin end surface gap 428 corresponds to a "second fin end surface gap".

As in 20th and 21 is shown, the fin end surface gap 428 , along a direction perpendicular to the axis of rotation Axr1 considered, between the end surface opening ribs 426 and 427 and the end surface of the ball valve 42 in the direction of the axis of rotation Axr1 observed.

Accordingly, it is possible to adjust the water pipe resistance in the end surface openings 415 and 425 to reduce.

As in 20th and 22 is the end surface opening rib 417 formed so that the surface on the side of the ball valve 42 with respect to the axis of rotation Axr1 is inclined. The end surface opening rib 427 is designed so that the surface on the side of the ball valve 41 with respect to the axis of rotation Axr1 is inclined.

Accordingly, it is possible to adjust the water pipe resistance around the end surface opening ribs 417 and 427 to reduce.

Next is a manufacturing process of the valve 30th described. In the present embodiment, the valve 30th manufactured using the so-called die-slide injection (DSI).

As in 29 is shown is a molding device 100 with a first shape 110 , a second form 120 and the like. The first form 110 has a first outer shape 111 and a first inner shape 112 on. The second form 120 has a second outer shape 121 and a second inner shape 122 on.

The first exterior shape 111 has a first concave surface 113 on in a hemispherical shape from an end surface on the side of the first inner shape 112 is excluded. The first concave surface 113 is designed so that the shape of the outer peripheral wall of the ball valves 41 . 42 and 43 at the outer peripheral wall of the first partial body 33 equivalent.

The first interior shape 112 has a first convex surface 114 on in a hemispherical shape from an end surface on the side of the first outer shape 111 protrudes. The first convex surface 114 is designed so that the shape of the inner peripheral wall of the ball valves 41 . 42 and 43 at the outer peripheral wall of the first partial body 33 equivalent. It should be noted that there is such a setting that when the first outer shape 111 and the first inner shape 112 butt, the distance between the first concave surface 113 and the first convex surface 114 within a range of at least part of the direction of the axis of rotation Axr1 and the circumferential direction of the valve body 31 is equal to.

The second outer shape 121 has a second concave surface 123 on in a hemispherical shape from an end surface on the side of the second inner shape 122 is excluded. The second concave surface 123 is designed so that the shape of the outer peripheral wall of the ball valves 41 . 42 and 43 in the outer peripheral wall of the second partial body 34 equivalent.

The second inner shape 122 has a second convex surface 124 on in a hemispherical shape from an end surface on the side of the second outer shape 121 protrudes. The second convex surface 124 is designed so that the shape of the inner peripheral wall of the ball valves 41 . 42 and 43 in the outer peripheral wall of the second partial body 34 equivalent. It should be noted that there is such a setting that when the second outer shape 121 and the second inner shape 122 abut, the distance between the second concave surface 123 and the second convex surface 124 within a range of at least part of the direction of the axis of rotation Axr1 and the circumferential direction of the valve body 31 is equal to.

The manufacturing process of the valve 30th includes the following processes.

(Primary molding process)

In a primary molding process, the first part body 33 and the second part of the body 34 accordingly with the first form 110 and the second form 120 resin molded. In particular, as in (a) in 29 is shown, the first outer shape 111 and the first inner shape 112 brought into contact with each other, then the second outer shape 121 and the second inner shape 122 brought into contact and melted resin between the first concave surface 113 and the first convex surface 114 as well as between the second concave surface 123 and the second convex surface 171 injected.

As in 30th shown, that flows from an injection part 130 the molding device 100 injected resin over a sprue 131 , a runner 132 , Gates 133 and 134 towards the first form 110 and the second form 120 , If the first partial body 33 and the second part of the body 34 cooled and solidified, the primary molding process is complete.

If in the primary molding process the first part body 33 and the second part of the body 34 resin-molded is the distance between the first concave surface 113 and the first convex surface 114 and the second concave surface 123 and the second convex surface 171 within a range of at least part of the direction of the axis of rotation Axr1 and equal to the circumferential direction.

Accordingly, it is possible to change the thickness in at least part of the valve body 31 to be uniform or even. This configuration enables the accuracy of the spherical surface of the outer peripheral wall of the valve body 31 further improve and the flow path area of the valve body flow path 300 to enlarge further.

(Pushing process)

In a sliding process after the primary molding process, the first part body 33 or the second part of the body 34 in the first form 110 or the second form 120 so moved that the respective connecting surfaces 331 and 341 of the first part of the body 33 and the second part of the body 34 face each other. In particular, as in (b) in 29 is shown, the first inner shape 112 from the first outer shape 111 removed the second inner shape 122 becomes the second outer shape 121 removed and the first partial body 33 in the first outer shape 111 is moved so that the respective connecting surfaces 331 and 341 of the first part of the body 33 and the second part of the body 34 face each other.

In the sliding process, it is possible to use the valve 30th to manufacture efficiently.

(Shaft assembly process)

In a shaft assembly process after the sliding process, the shaft 32 on the axis of rotation Axr1 of the valve body 31 placed. In particular, as in (c) in 29 is shown the wave 32 on the axis of rotation Axr1 between the first partial body 33 and the second partial body 34 placed.

At the lower support column 154 with one end as the point of support is the side of the other end towards the side of the central axis CAx1 swiveling.

The first interior shape 160 is at the respective other ends of the eight upper support columns 153 intended. That means there are eight first inner shapes 160 intended. The second inner shape 170 is at the respective other ends of the eight lower support columns 154 intended. That means there are eight second inner shapes 170 intended.

As in 38 is shown, has the first inner shape 160 a first convex surface 161 on part of the outer wall. The first convex surface 161 is spherical. The second inner shape 170 has a second convex surface on part of the outer wall 171 on. The second convex surface 171 is spherical.

As described above, the present embodiment relates to the valve device 10 , which is configured so that the cooling water in the machine 2 of the vehicle 1 controls. The valve device 10 points the case 20th , the valve 30th , the pipe element 50 and the pipe fastener 540 on.

The housing 20th owns the main body of the case 21 that the interior 200 defined in the housing-side fixing parts ( 251 to 256 ) that are integral with the case main body 21 are formed, the housing-side mounting holes ( 261 to 266 ), which are formed in the housing-side fixing parts, and the connections ( 220 . 221 . 222 . 223 and 224 ) the interior 200 with the outside of the case main body 21 connect.

The valve 30th has the valve body 31 that in the interior 200 about the axis of rotation Axr1 is rotatable, the inside of the valve body 31 trained valve body flow path 300 and the valve body openings ( 410 . 420 and 430 ) the valve body flow path 300 with the outside of the valve body 31 connect. The valve 30th is configured to control the state of communication between the Valve body flow path 300 and the connections via the valve body openings with the rotational position of the valve body 31 to change.

The pipe element 50 has the cylindrical tubes ( 511 . 512 . 513 and 514 ), whose interior with the connections ( 221 . 222 . 223 and 224 ) communicates, the pipe-side fixing parts ( 531 to 536 ), which are formed integrally or in one piece with the tubes and are fixed to the housing-side fixing parts, and the tube-side fastening holes ( 541 to 546 ), which are formed in the pipe-side fixing parts.

The pipe fastener 540 is through the pipe-side mounting holes ( 541 to 546 ) into the mounting holes on the housing ( 261 to 266 ) to be screwed around the pipe-side fixing parts ( 531 to 536 ) on the housing-side fixing parts ( 251 to 256 ) to fix.

The housing-side fixing parts ( 251 to 256 ) form the gap ( Sh1 ) between the housing-side fixing parts and the outer wall of the housing main body 21 ,

Accordingly, it is in a case where the tubular member 50 with the fastener 240 on the housing 20th is attached, even if there is a crack in the housing-side fixing parts ( 251 to 256 ) occurs, possibly, the expansion of the crack toward the case main body 21 to suppress. This configuration allows leakage of the cooling water by fixing the pipe element 50 on the housing 20th to suppress.

Because in the present embodiment, the outlet port 221 with the cooler 5 is connected and the flow rate is high, it is possible to effectively suppress leakage of the cooling water by expanding the crack, particularly from the fixing parts on the housing side 251 and 254 near the outlet port 221 , from the housing-side fixing parts ( 215 to 256 ) towards the main body of the case 21 is suppressed.

The outlet connections 221 to 223 are coaxial with the ends of the seal assembly 35 provided pipes 511 to 513 educated.

Accordingly, it is possible to use the tubular element 50 on which the several sealing units 35 are mounted from one direction to the case main body 21 to assemble.

As in 42 . 50 and 51 shown is the valve device 10 with the seal 509 Mistake. The seal 509 is formed with an elastic element such as rubber. The seal 509 is between the tubular element 50 and the pipe mounting surface 202 of the main body of the case 21 on the radially outer side of the respective tubes 511 to 513 provided and configured so that this between the tubular element 50 and the case main body 21 seals fluid-tight.

As in 51 is shown, the tubular element 50 on the case main body 21 be installed in a state in which the three sealing units 35 in the pipes 511 to 513 are held. It should be noted that the seal 509 together with the pipe element 50 in a state on the case main body 21 is mounted in which the seal 509 in a sealing groove 521 that in the pipe connection part 52 is trained, is fitted. That is, it is possible to use the tubular element 50 on which the several sealing units 35 and the seal 509 are mounted on the main body of the housing from one direction at the same time 21 to assemble.

Furthermore, by assembling the multiple elements at once to reduce the number of assembly steps, it is possible to reduce several inconveniences that may occur when assembling the multiple elements to a single one, in order to improve the quality of the valve device 10 to improve. This is important because of those in the vehicle 1 mounted devices a high quality is expected.

As in 47 shown are the outlet ports 221 to 223 and the relief port 224 formed so that the center is positioned on a straight line, the two housing-side mounting holes of the plurality of housing-side mounting holes ( 261 to 266 ) connects, or within a triangle that is formed with the three housing mounting holes.

In particular, the outlet port 221 formed so that the center is within a triangle To1 is positioned by connecting the center of the case-side mounting hole 261 , the middle of the housing-side mounting hole 262 and the center of the case-side mounting hole 264 is formed. The outlet port 222 is designed so that the center is on a straight line Lo1 is positioned, which is the center of the housing-side mounting hole 262 and the center of the case-side mounting hole 265 connects. The outlet port 223 is designed so that the center is within a triangle To2 is positioned by connecting the center of the case-side mounting hole 262 , the middle of the housing-side mounting hole 263 and the center of the case-side mounting hole 266 is formed.

As in 42 is shown, the housing 20th the pipe mounting surface 202 on that on the outer wall of the housing main body 21 is designed so that it is the tubular element 50 opposed in a state in which the tubular member 50 on the main body of the case 21 is appropriate. The one in the main body of the case 21 trained connections include the three at the pipe mounting surface 202 open outlet ports ( 221 to 223 ) and a relief connection 224 ,

As in 47 shown is the valve device 10 with the relief valve 39 Mistake. The relief valve 39 is in the relief port 224 intended. The relief valve 39 enables or blocks communication between the interior 200 and the outside of the case main body 21 via the relief connection 224 according to the condition. In particular, the relief valve 39 opened when a predetermined condition is met, that is, when the temperature of the cooling water is equal to or higher than a predetermined temperature. The relief valve 39 enables communication between the interior 200 and the outside of the case main body 21 , that is, the space inside the tube 511 , via the relief connection 224 , When the temperature of the cooling water is lower than the predetermined temperature, the relief valve blocks 39 the communication described above.

As in 47 is shown, at least two ( 221 to 223 ) of the three outlet connections ( 221 to 223 ) designed so that the center of the respective openings is straight on a connection arrangement Lp1 as a straight line on the pipe mounting surface 202 is positioned. It should be noted that the connection arrangement is straight Lp1 parallel to the mounting surface 201 runs and on the virtual level Vp5 is positioned.

The relief port 224 is formed so that the center of the opening is at a position away from the terminal arrangement line Lp1 towards the opposite side of the mounting surface 201 is positioned.

Accordingly, it is possible to connect the relief 224 in the housing main body 21 train and at the same time the external structure of the housing main body 21 by reducing the three outlet ports ( 221 to 223 ) can be arranged linearly.

It should be noted that the relief connection 224 in the housing main body 21 is designed so that part of the relief connection 224 between the outlet port 221 and the outlet port 222 is positioned.

As in 47 are straight when viewed along the direction of the terminal arrangement Lp1 at least two ( 221 to 223 ) of the three outlet connections ( 221 to 223 ) and the relief connection 224 designed so that they partially overlap.

Accordingly, it is possible to design the outer body of the main body 21 in which the relief port 224 is trained to further reduce.

As in 47 shown is the relief port 224 formed so that the center of the opening is straight on a relief arrangement Lr1 is positioned, which is a straight line on the pipe mounting surface 202 parallel to the straight line Lp1 equivalent. Note that the relief arrangement is straight Lr1 on the opposite side to the mounting surface 201 with respect to the straight line arrangement Lp1 is positioned.

When viewed along the direction of the straight line arrangement Lp1 are part of at least two ( 221 to 223 ) of the three Exhaust ports ( 221 to 223 ) on the side of the relief arrangement straight line Lr1 with respect to the straight line arrangement Lp1 , and part of the relief port 224 on the side of the connection arrangement straight line Lp1 with respect to the relief arrangement straight line Lr1 formed so that they are partially overlapped with each other or overlap.

Accordingly, it is possible to design the outer body of the main body 21 in which the relief port 224 is trained to further reduce.

As in 47 is shown, at least two ( 261 to 263 ) of the several mounting holes on the housing ( 261 to 266 ) on a mounting hole arrangement line Lh1 formed that corresponds to a straight line that is on the side of the relief port 224 with respect to the straight line arrangement Lp1 is positioned. Note that the mounting hole arrangement is straight Lh1 parallel to the straight line Lp1 and to the relief arrangement line Lr1 lies and on the opposite side of the straight line Lp1 with respect to the relief arrangement straight line Lr1 is positioned.

As in 47 shown is the relief port 224 formed so that it is straight with part of the mounting hole arrangement Lh1 is overlapped.

Accordingly, it is possible to design the outer body of the main body 21 in which the relief port 224 is trained to further reduce.

As in 50 shown have the tubes 511 to 513 a pipe main body 501 and a pipe end 502 that is on the opposite side to the exhaust ports 221 to 223 (Pipe connection part 52 ) of the main pipe body 501 is formed, the inner diameter of which is larger than the inner diameter of the tube main body 501 and whose outside diameter is larger than the outside diameter of the pipe main body 501 ,

If the pipe end 502 For example, by violent extraction, it is possible to remove the shape and at the same time the pipe end 502 easy to redesign inside, causing cracks in the pipe end 502 can be suppressed. This configuration enables the cooling water to leak from the pipe end 502 to suppress.

Because the outside diameter of the pipe end 502 is larger than the outer diameter of the main pipe body 501 , it is possible to fall out or loosen from a with the pipe end 502 connected hose or similar to prevent.

As in 50 is shown, the tubes 511 to 513 a protrusion 503 on that of an outer wall of the pipe main body 501 protrudes outwards.

With the pipe protrusion 503 it is possible to position the hose in relation to the pipes 511 to 513 easy to determine and a deep penetration of the tube in the pipes 511 to 513 to suppress.

As in 47 is shown is the pipe protrusion 503 on the virtual level Vp5 parallel to the mounting surface 201 educated.

Accordingly, it is possible to change the size of the tubular element 50 in a direction perpendicular to the mounting surface 201 to reduce and the external structure of the valve device 10 to reduce.

It should be noted that a pipe ledge 503 with respect to the pipe 511 is trained. With respect to the pipe 512 are two tube protrusions 503 trained to the pipe 512 between the pipe protrusions 503 to record. With respect to the pipe 513 are two tube protrusions 503 trained to the pipe 513 between the pipe protrusions 503 record (see 50 ).

As in 50 is shown has the tubular element 50 the multiple pipes ( 511 to 514 ) and the pipe connection part 52 which parts of the multiple pipes ( 511 to 514 ) on the side of the housing body 21 connects.

Accordingly, it is possible to reduce the number of elements, and it is possible to improve the sealability between the tubular element 50 and the case main body 21 ensure by the seal 509 between the pipe connection part 52 and the case main body 21 is provided.

As in 42 shown has the housing 20th the housing opening 210 that the interior 200 and the outside of the case main body 21 connects, and the cylindrical housing inner wall 211 , one end of which is with the housing opening 210 and the interior 200 forms. The valve 30th has the on the axis of rotation Axr1 intended shaft 32 ,

The valve device 10 is provided with the in the housing opening 210 provided separation part main body 61 to the interior 200 from the outside of the case main body 21 to separate, and the separation part 60 with that in the partition part main body 61 trained Shaft insertion hole 62 so that one end of the wave 32 through the shaft insertion hole 62 can be introduced.

The inside diameter of the housing opening 210 is larger than the inside diameter of the end of the housing inner wall 211 on the opposite side to the housing opening 210 ,

Accordingly, it is possible to define the flow path areas of the interior 200 on the side of the case opening 210 to enlarge. This configuration makes it possible to increase the flow rate of the cooling water, particularly toward the outlet port side 221 (Cooler 5 ) should flow, as on the side of the housing opening 210 educated.

As in 42 is shown is the ring sealing element 600 provided that between the housing opening 210 and the separation part main body 61 of the separation part 60 is provided and configured so that this between the housing opening 210 and the separation part 60 seals fluid-tight.

If the inside diameter of the housing opening 210 is constant, it is correspondingly possible, the ring sealing element 600 to use with a standard shape, the inside diameter and outside diameter of which are constant, and it is possible to reduce the cost.

As in 42 is shown is the housing inner wall 211 formed in a conical or conical shape so that the inner diameter from the side of the housing opening 210 towards the opposite side of the housing opening 210 gets smaller.

Accordingly, it is possible to change the flow path area of the interior 200 towards the side of the case opening 210 gradually increase. Because with the inner wall of the housing 211 no step is formed, it is also possible to the water pipe resistance in the interior 200 to reduce.

As in 47 shown are at least two (outlet connections 221 to 223 ) of the several in the main body of the case 21 trained connections designed so that they are parallel to the mounting surface in one direction 201 are arranged.

Accordingly, it is possible to size the main body of the case 21 in a direction perpendicular to the mounting surface 201 to reduce and the external structure of the valve device 10 to reduce.

As in 49 shown corresponds to the pipe fastening element 540 a self-tapping screw in the mounting holes on the housing side 261 to 266 can be screwed while threading is in progress.

Accordingly, it is not necessary to use a metal element with a thread groove or the like. in the housing-side fixing parts 251 to 256 to use. Because the housing gap Sh1 between the housing-side fixing parts 251 to 256 and the outer wall of the case main body 21 is formed, it is also when screwing in the pipe fastening element 540 into the mounting holes on the housing side 261 to 266 a crack in the housing-side fixing parts 251 to 256 occurs, possible the expansion of the crack on the housing main body 21 to suppress.

As in 52 is shown, the separation part 60 the separation through hole 65 from the shaft insertion hole 62 extends outward and at the outer wall of the partition part main body 61 is open.

As described above, the present embodiment relates to the valve device 10 , which is configured so that the cooling water in the machine 2 of the vehicle 1 controls. The valve device 10 is with the housing 20th , the valve 30th , the separation part 60 and the drive part 70 Mistake.

The housing 20th owns the main body of the case 21 that the interior 200 defined in the connectors ( 220 . 221 . 222 and 223 ) the interior 200 with the outside of the case main body 21 connect, and the case opening 210 that the interior 200 with the outside of the case main body 21 connects.

The valve 30th has the valve body 31 , the Axr1 in the interior 200 is rotatable about the axis of rotation, the inside of the valve body 31 trained valve body flow path 300 , the valve body openings ( 410 . 420 and 430 ) the valve body flow path 300 with the outside of the valve body 31 connect, and that on the axis of rotation Axr1 intended shaft 32 , The valve 30th is configured to communicate the state of communication between the valve body flow path 300 and the connections via the valve body openings with the rotational position of the valve body 31 changes.

The separation part 60 has the in the housing opening 210 provided separation part main body 61 to the interior 200 from the outside of the case main body 21 to separate and the shaft insertion hole 62 that in the separation part main body 61 is formed so that one end of the shaft 32 through the shaft insertion hole 62 can be introduced.

The drive part 70 is on the the interior 200 opposite side with respect to the separation part 60 provided and can the valve body 31 over one end of the wave 32 drive rotating.

The separation part 60 has the separation through hole 65 from the shaft insertion hole 62 extends outward and at the outer wall of the partition part main body 61 is open.

Accordingly, it is possible to remove the cooling water from the interior 200 through the shaft insertion hole 62 towards the side of the drive part 70 flows to the separation through hole 65 respectively. This configuration allows the cooling water to flow inside 200 to the side of the drive part 70 to suppress.

The separation through hole 65 is designed so that the cross-sectional shape perpendicular to the axis corresponds to an elliptical or rectangular shape.

Accordingly, it is possible to influence a surface tension in the separation through hole 65 suppress and at the same time the external structure of the partition part main body 61 to reduce, and it is possible to flow the cooling water in the separation through hole 65 to facilitate.

Note that the separation through hole 65 is designed so that the short direction of the cross section is parallel to an axis Axh1 of the shaft insertion hole 62 runs. Accordingly, it is possible to structure the outer part of the partition main body 61 in the direction of the axis Axh1 to reduce.

As in 52 is shown, the housing 20th the case through hole 270 on, which is from the inner wall of the housing opening 210 extends outwards, which is at the outer wall of the housing main body 21 is opened, and that is formed so that this with the separation through hole 65 can be associated. It should be noted that the housing through hole 270 at the end surface of the case main body 21 on the opposite side to the pipe mounting surface 202 is open.

Accordingly, it is possible to remove the cooling water leading to the separation through hole 65 flows from the case through hole 270 to deliver to the outside.

It should be noted that there is a large amount of cooling water coming from the interior 200 to the side of the drive part 70 flows, is possible, the cooling water through the separation through hole 65 and the case through hole 270 to release to the outside, and that it is possible for the user to leak the cooling water at the shaft insertion hole 62 display. This configuration allows the user to respond to the leak that requires countermeasures.

If the amount of cooling water coming from the interior 200 to the side of the drive part 70 flows, on the other hand, it is small, it is possible to keep the cooling water in the separation through hole 65 and the case through hole 270 and it is possible that the user will not leak the cooling water at the shaft insertion hole 62 noticed. This configuration makes it possible to suppress that the user reacts to leaks that do not require countermeasures.

The case through hole 270 is designed so that a cross-sectional shape perpendicular to the axis corresponds to an elliptical or rectangular shape.

Accordingly, it is possible to determine the influence of a surface tension on the housing through hole 270 to suppress and at the same time the external structure of the housing main body 21 to reduce, and it is possible to reduce the cooling water flow in the case through hole 270 to facilitate.

It should be noted that the housing through hole 270 is designed so that the short direction of the cross section is parallel to the axis Axh1 of the shaft insertion hole 62 runs. Accordingly, it is possible to design the outer body of the main body 21 in the direction of the axis Axh1 to reduce.

As in 52 are the separation through hole 65 and the case through hole 270 formed coaxially to each other.

Accordingly, it is possible to remove the cooling water to the separation through hole 65 flows from the case through hole in a simple manner 270 to deliver to the outside.

As in 52 shown is the valve device 10 with an axle sealing element 603 and the ring sealing element 600 Mistake. The axis sealing element 603 is made of an elastic element, for example mainly made of rubber, in a ring shape. The axis sealing element 603 is between the wave 32 and the shaft insertion hole 62 on the side of the interior 200 with respect to the separation through hole 65 intended. The axis sealing element 603 is configured to between the shaft 32 and the shaft insertion hole 62 to seal in a fluid-tight manner.

The ring sealing element 600 is made of an elastic element, such as rubber, in a ring shape. The ring sealing element 600 is between the separation part main body 61 and the inner wall of the housing opening 210 on the side of the interior 200 with respect to the case through hole 270 intended. The ring sealing element 600 is configured to between the partition part main body 61 and the inner wall of the housing opening 210 to seal in a fluid-tight manner. It should be noted that the axis sealing element 603 and the ring sealing element 600 corresponding to a "first sealing element" and a "second sealing element".

It is the same with the axle sealing element 603 possible leakage of cooling water from the interior 200 through the shaft insertion hole 62 to the side of the drive part 70 to suppress. It is also with the ring sealing element 600 possible leakage of cooling water from the interior 200 outward over the distance between the separation part main body 61 and the housing opening 210 to suppress.

Furthermore, the axis sealing element 603 provided at a position that is related to the separation through hole 65 by a predetermined distance to the side of the interior 200 away. Accordingly, it is possible to have a space between the separation through hole 65 and the axis sealing element 603 to train.
