弁部材側開口233は、弁部材20の回転に合わせて空調用通路180に連通可能なよう形成されている。すなわち、空調用配管18のシート182は、弁部材側開口233を形成する外壁面231に押し付けられている。 Thesecond cylinder part 23 has valve member side openings 232 and 233 as “other valve member side openings” that communicate the space 200 with the outside of the second cylinder part 23.
The valvemember side opening 232 is formed to be able to communicate with the oil cooler passage 170 according to the rotation angle of the valve member 20. That is, the seat 172 of the oil cooler pipe 17 is pressed against the outer wall surface 231 forming the valve member side opening 232.
The valvemember side opening 233 is formed so as to be able to communicate with the air conditioning passage 180 in accordance with the rotation of the valve member 20.

規制部19は、図14に示すように、ハウジング底部104の弁部材底部21に対向する端面109に略円弧状に形成されている部位である。第一実施形態では、規制部19は、第一ハウジング10と一体に形成されている。規制部19は、端面109から回転軸RA25に沿う方向に突出し、突出先の先端が、図2に示すように、窪み210に位置する。規制部19は、図14に示すように、周方向の側面191,192が回転軸RA25からみて径外方向に放射状に延びるよう形成されている。
As shown in FIG. 14, the restricting portion 19 is a portion formed in a substantially arc shape on the end surface 109 of the housing bottom portion 104 facing the valve member bottom portion 21. In the first embodiment, the restricting portion 19 is formed integrally with the first housing 10. The restricting portion 19 protrudes from the end face 109 in the direction along the rotation axis RA25, and the tip of the protruding tip is located in the depression 210 as shown in FIG. As shown in FIG. 14, the restricting portion 19 is formed such that circumferential side surfaces 191 and 192 extend radially outward from the rotational axis RA25.
ここで、当接部24と規制部19との位置関係について、図15に基づいて説明する。図15は、図2のXV-XV線断面図であって、当接部24と規制部19とが係合する部位における回転軸RA25に垂直な断面図を示す。なお、図15では、便宜的に、弁部材20が回転する方向を「時計回り」、または、「反時計回り」として説明する。
Here, the positional relationship between the contact portion 24 and the restricting portion 19 will be described with reference to FIG. FIG. 15 is a cross-sectional view taken along the line XV-XV in FIG. 2 and is a cross-sectional view perpendicular to the rotation axis RA25 at a portion where the contact portion 24 and the restricting portion 19 engage. In FIG. 15, for convenience, the direction in which the valve member 20 rotates is described as “clockwise” or “counterclockwise”.
図15は、当接部24が有する側壁241の側面244と規制部19の側面191とが当接している状態を示している。この状態では、弁部材20は、時計回りの回転が規制されている。
一方、図15に示す状態から、弁部材20が反時計回りに回転すると、当接部24が有する側壁242の側面245が規制部19の側面192に当接する。これにより、弁部材20は、反時計回りの回転が記載される。
すなわち、弁部材20は、弁部材20の周方向における当接部24と規制部19との係合によって、図15の二点鎖線α1で示す角度範囲における回転が許容されることとなる。 FIG. 15 shows a state where theside surface 244 of the side wall 241 and the side surface 191 of the regulating portion 19 are in contact with each other. In this state, the valve member 20 is restricted from rotating clockwise.
On the other hand, when thevalve member 20 rotates counterclockwise from the state shown in FIG. 15, the side surface 245 of the side wall 242 of the contact portion 24 contacts the side surface 192 of the restricting portion 19. Thereby, the valve member 20 is described to rotate counterclockwise.
That is, thevalve member 20 is allowed to rotate in an angle range indicated by a two-dot chain line α1 in FIG. 15 due to the engagement between the contact portion 24 and the restricting portion 19 in the circumferential direction of the valve member 20.
一方、図15に示す状態から、弁部材20が反時計回りに回転すると、当接部24が有する側壁242の側面245が規制部19の側面192に当接する。これにより、弁部材20は、反時計回りの回転が記載される。
すなわち、弁部材20は、弁部材20の周方向における当接部24と規制部19との係合によって、図15の二点鎖線α1で示す角度範囲における回転が許容されることとなる。 FIG. 15 shows a state where the
On the other hand, when the
That is, the
(a)第一実施形態による流体制御弁1では、弁部材20の回転を規制する規制部19に当接可能な当接部24は、弁部材20が有する凹状の窪み210に形成されている。これにより、弁部材20は、弁部材20から突出していない当接部24を有することができるため、当接部24が弁部材20から突出するよう設けられる場合に比べ、弁部材20の体格を小さくすることができる。したがって、弁部材20の体格を小さくしつつ弁部材20の回転角度を所望の角度範囲内とすることができる。
(A) In the fluid control valve 1 according to the first embodiment, the abutting portion 24 that can abut on the regulating portion 19 that regulates the rotation of the valve member 20 is formed in a concave recess 210 of the valve member 20. . Thereby, since the valve member 20 can have the contact part 24 which does not protrude from the valve member 20, compared with the case where the contact part 24 is provided so that it may protrude from the valve member 20, the physique of the valve member 20 is improved. Can be small. Therefore, the rotation angle of the valve member 20 can be set within a desired angle range while reducing the size of the valve member 20.
(b)弁部材底部21では、第一筒部22が設けられる径方向外側の縁部から貫通孔211に向かうにしたがってハウジング底部104から離れるよう形成することによって窪み210が形成されている。これにより、窪み210は、弁部材底部21のシャフト25が位置する中心から径外方向に向かって深さが浅くなるよう形成されるため、空間200を流れる冷却水の流動抵抗を小さくすることができる。したがって、空間200における冷却水の流れを弁部材側開口222,232,233にスムーズに導くことができる。
(B) In the valve member bottom portion 21, a recess 210 is formed by forming it away from the housing bottom portion 104 toward the through hole 211 from the radially outer edge where the first cylindrical portion 22 is provided. Thereby, since the recess 210 is formed so that the depth becomes shallower in the radial direction from the center where the shaft 25 of the valve member bottom 21 is located, the flow resistance of the cooling water flowing through the space 200 can be reduced. it can. Therefore, the flow of the cooling water in the space 200 can be smoothly guided to the valve member side openings 222, 232, 233.
(c)また、窪み210の深さを弁部材底部21のシャフト25が位置する中心から径外方向に向かって深さが浅くなるよう形成すると、回転軸RA25近傍における当接部24の回転軸RA25に沿う方向の長さを比較的長くすることができる。これにより、当接部24の規制部19との接触面積を大きくすることができるため、規制部19との係合で作用する応力による当接部24の破損を防止することができる。
(C) Further, when the depth of the recess 210 is formed so as to become shallower in the radially outward direction from the center where the shaft 25 of the valve member bottom 21 is located, the rotational axis of the contact portion 24 in the vicinity of the rotational axis RA25. The length in the direction along RA25 can be made relatively long. Thereby, since the contact area with the control part 19 of the contact part 24 can be enlarged, the damage of the contact part 24 by the stress which acts by engagement with the control part 19 can be prevented.
(d)また、弁部材20は、空間200側の面にリブ212を複数有している。これにより、空間200を流れる冷却水を弁部材底部21のシャフト25が位置する中心から径外方向に向かってスムーズに導くことができる。
(D) Moreover, the valve member 20 has a plurality of ribs 212 on the surface on the space 200 side. Thereby, the cooling water flowing through the space 200 can be smoothly guided from the center where the shaft 25 of the valve member bottom portion 21 is located toward the radially outward direction.
(e)また、空間200側の面にリブ212を設けることによって弁部材底部21の強度を向上することができる。これにより、規制部19との係合で作用する応力による当接部24の破損を確実に防止することができる。
(E) Further, the strength of the valve member bottom 21 can be improved by providing the rib 212 on the surface on the space 200 side. Thereby, damage of the contact part 24 by the stress which acts by engagement with the control part 19 can be prevented reliably.
(f)また、規制部19は、第一ハウジング10と一体に形成されている。これにより、当接部24との係合によって、規制部19が第一ハウジング10に対してずれることを防止できる。
(F) The restricting portion 19 is formed integrally with the first housing 10. Thereby, it can prevent that the control part 19 slip | deviates with respect to the 1st housing 10 by engagement with the contact part 24. FIG.
(g)当接部24の側面244,245及び規制部19の側面191,192は、回転軸RA25からみて径外方向に放射状に形成されている。これにより、側面244と側面191とが当接するとき、及び、側面245と側面192とが当接するとき、それぞれの接触面積を大きくすることができる。したがって、当接部24と規制部19との係合で作用する応力による当接部24及び規制部19の破損を確実に防止することができる。
(G) The side surfaces 244 and 245 of the abutting portion 24 and the side surfaces 191 and 192 of the restricting portion 19 are formed radially outwardly from the rotational axis RA25. Thereby, when the side surface 244 and the side surface 191 come into contact with each other and when the side surface 245 and the side surface 192 come into contact with each other, the respective contact areas can be increased. Therefore, it is possible to reliably prevent the contact portion 24 and the restriction portion 19 from being damaged due to the stress acting on the engagement between the contact portion 24 and the restriction portion 19.
(h)当接部24は、二つの側壁241,242を支持するリブ243を有する。これにより、ブロック状の当接部を成形する場合に比べ当接部24を形成するために必要な樹脂の量を低減することができる。
(H) The contact portion 24 has a rib 243 that supports the two side walls 241 and 242. Thereby, compared with the case where a block-shaped contact part is shape | molded, the quantity of resin required in order to form the contact part 24 can be reduced.
(i)挿入孔101を形成する第一ハウジング10の縁部には、流体制御弁1をシリンダヘッド501に組み付けるときOリング110を設けることが可能な溝102が形成されている。また、第一ハウジング10は樹脂から形成されている、これにより、軸受14を挿入孔101に挿入するとき、溝102が変形することによって軸受14の変形を抑制することができる。
(I) A groove 102 in which an O-ring 110 can be provided when the fluid control valve 1 is assembled to the cylinder head 501 is formed at the edge of the first housing 10 that forms the insertion hole 101. In addition, the first housing 10 is made of resin. Accordingly, when the bearing 14 is inserted into the insertion hole 101, deformation of the bearing 14 can be suppressed by deformation of the groove 102.
(j)複数の連結部143は、軸受14をシャフト25の回転軸RA25に沿う方向から見たとき、隣り合う連結部143同士の間隔が同じ角度αとなるよう設けられている。これにより、軸受14を第一ハウジング10に圧入するときに発生する力を均等に分散し、軸受のずれや変形を防止することができる。
(J) When the bearing 14 is viewed from the direction along the rotation axis RA25 of the shaft 25, the plurality of connecting portions 143 are provided such that the intervals between the adjacent connecting portions 143 are the same angle α. Thereby, the force generated when the bearing 14 is press-fitted into the first housing 10 can be evenly distributed, and the displacement and deformation of the bearing can be prevented.
(k)軸受14では、環状部142と軸受部140とが回転軸RA25に沿ってオフセットするよう形成されている。これにより、軸受14を第一ハウジング10に圧入するときに発生する力が直接軸受部140に作用することを防止することができる。
(K) In the bearing 14, the annular portion 142 and the bearing portion 140 are formed so as to be offset along the rotation axis RA25. Thereby, it is possible to prevent the force generated when the bearing 14 is press-fitted into the first housing 10 from directly acting on the bearing portion 140.
(l)連結部143は、中央部141に接続する側の端部が中央部141とほぼ同じ長さになるよう形成され、回転軸RA25から離れるにしたがって回転軸RA25に沿う方向の長さが短くなるよう形成されている。これにより、軸受14を第一ハウジング10に圧入するときに発生する力による変形を比較的大きな連結部143の撓みに変換し、軸受部140に作用する力を小さくすることができる。
(L) The connecting portion 143 is formed so that the end on the side connected to the central portion 141 has substantially the same length as the central portion 141, and the length in the direction along the rotational axis RA25 increases as the distance from the rotational axis RA25 increases. It is formed to be shorter. Thereby, the deformation due to the force generated when the bearing 14 is press-fitted into the first housing 10 can be converted into a relatively large deflection of the connecting portion 143, and the force acting on the bearing portion 140 can be reduced.
(m)隣り合う連結部143の間には冷却水が流れることが可能な隙間が形成されている。隙間が形成されている部位は、比較的剛性が低くなるため、軸受14を第一ハウジング10に圧入するときの力を剛性が低い部位の撓みに変換し、軸受部140に作用する力を小さくすることができる。
(M) A gap through which cooling water can flow is formed between adjacent connecting portions 143. Since the portion where the gap is formed has relatively low rigidity, the force when the bearing 14 is press-fitted into the first housing 10 is converted into the bending of the portion having low rigidity, and the force acting on the bearing portion 140 is reduced. can do.
(n)軸受14を第一ハウジング10に圧入するとき、軸受14の傾斜面144と第一ハウジング10の当接面103とを当接させることによって、軸受14を第一ハウジング10の所定の位置に組み付けることができる。これにより、シャフト25と軸受14とのずれによる回転異常の発生を防止することができる。
(N) When the bearing 14 is press-fit into the first housing 10, the inclined surface 144 of the bearing 14 and the abutting surface 103 of the first housing 10 are brought into contact with each other, so that the bearing 14 is positioned at a predetermined position of the first housing 10. Can be assembled. Thereby, it is possible to prevent the occurrence of rotation abnormality due to the deviation between the shaft 25 and the bearing 14.
(o)第一ハウジング10が有する排水路108は、シール部材107を通って軸受部106が設けられている側の貫通孔105に侵入する冷却水を外部に排出し、弁部材収容空間100の冷却水が収容室150に侵入することを防止する。これにより、収容室150に収容されている回転角センサ152やバルブギア156などのギア類、収容室150に露出しているモータ157などに冷却水がかかり破損することを防止できる。また、排水路108から水が排出されることによってシール部材107を通って冷却水が漏れていることを早期に発見することできるため、シール部材107の不具合を早期に検出することができる。
(O) The drainage passage 108 of the first housing 10 discharges the cooling water entering the through hole 105 on the side where the bearing portion 106 is provided through the seal member 107 to the outside of the valve member accommodating space 100. Cooling water is prevented from entering the storage chamber 150. Thereby, it is possible to prevent the cooling water from being applied to the gears such as the rotation angle sensor 152 and the valve gear 156 stored in the storage chamber 150 and the motor 157 exposed in the storage chamber 150 from being damaged. Further, since it is possible to detect at an early stage that the cooling water is leaking through the seal member 107 by discharging water from the drainage channel 108, the malfunction of the seal member 107 can be detected at an early stage.
(p)流体制御弁1では、第一ハウジング10側から見て、第一小ギア1542と第二大ギア1551とが噛み合う位置、バルブギア156と第二小ギア1552とが噛み合う位置、モータギア153と第一大ギア1541とが噛み合う位置の順となるよう、モータギア153、第一中間ギア154、第二中間ギア155、バルブギア156は配置されている。これにより、シャフト25の回転軸RA25に略垂直な方向において第一中間ギア154とバルブギア156とが近接するよう第二中間ギア155を配置することができる。したがって、流体制御弁1の回転軸RA25に略垂直な方向の体格を小さくすることができる。
また、図7に示すように、第一中間ギア154の第一大ギア1541は、第二中間ギア155の第二ギアシャフト1553の一部に重なるよう形成されている。これにより、流体制御弁1の回転軸RA25に略垂直な方向の体格をさらに小さくすることができるとともに、第二中間ギア155が第一ハウジング10から抜けることを第一中間ギア154によって防止することができる。 (P) In thefluid control valve 1, when viewed from the first housing 10 side, the position where the first small gear 1542 and the second large gear 1551 mesh, the position where the valve gear 156 and the second small gear 1552 mesh, and the motor gear 153 The motor gear 153, the first intermediate gear 154, the second intermediate gear 155, and the valve gear 156 are arranged so as to be in the order of positions where the first large gear 1541 meshes. Thereby, the second intermediate gear 155 can be arranged so that the first intermediate gear 154 and the valve gear 156 are close to each other in a direction substantially perpendicular to the rotation axis RA25 of the shaft 25. Therefore, the size of the fluid control valve 1 in the direction substantially perpendicular to the rotation axis RA25 can be reduced.
As shown in FIG. 7, the firstlarge gear 1541 of the first intermediate gear 154 is formed so as to overlap a part of the second gear shaft 1553 of the second intermediate gear 155. As a result, the size of the fluid control valve 1 in the direction substantially perpendicular to the rotation axis RA25 can be further reduced, and the second intermediate gear 155 can be prevented from coming off the first housing 10 by the first intermediate gear 154. Can do.
また、図7に示すように、第一中間ギア154の第一大ギア1541は、第二中間ギア155の第二ギアシャフト1553の一部に重なるよう形成されている。これにより、流体制御弁1の回転軸RA25に略垂直な方向の体格をさらに小さくすることができるとともに、第二中間ギア155が第一ハウジング10から抜けることを第一中間ギア154によって防止することができる。 (P) In the
As shown in FIG. 7, the first
(q)第一中間ギア154の第一ギアシャフト1543、及び、第二中間ギア155の第二ギアシャフト1553は、第一ハウジング10にインサートされている部位に複数の溝1544,1554が形成されている。これにより、インサートされる部位の長さを短くすることができるため、流体制御弁1の回転軸RA25に沿う方向の体格を小さくすることができる。
(Q) The first gear shaft 1543 of the first intermediate gear 154 and the second gear shaft 1553 of the second intermediate gear 155 are formed with a plurality of grooves 1544 and 1554 at portions inserted into the first housing 10. ing. Thereby, since the length of the site | part inserted can be shortened, the physique of the direction in alignment with rotating shaft RA25 of the fluid control valve 1 can be made small.
(r)従来、樹脂から形成されている弁部材に金属から形成されているシャフトがインサートされていると、弁部材の回転トルクの応力とシャフトの回転軸に対して略垂直な方向の力の応力とがシャフトがインサートされている弁部材の部位の同じ個所に集中するため、過大な応力がかかる。このため、弁部材が破損するおそれがある。
流体制御弁1では、シャフト25のインサート部253は回転軸RA25に略垂直な断面形状が多角形状となるよう形成されている。また、シャフト25は、インサート部253の両側には、外径がインサート部253の外径に比べ小さい溝254,255を有している。これにより、弁部材20の回転トルクによる応力はインサート部253に作用する一方、各配管16,17,18が有するばね165,175,185によるシャフト25の回転軸RA25に対して略垂直な方向の力を受けたときの応力は、溝254,255に作用し分散する。したがって、弁部材20の破損を防止することができる。 (R) Conventionally, when a shaft made of metal is inserted into a valve member made of resin, the stress of the rotational torque of the valve member and the force in a direction substantially perpendicular to the rotational axis of the shaft Since stress concentrates on the same part of the part of the valve member in which the shaft is inserted, excessive stress is applied. For this reason, there exists a possibility that a valve member may be damaged.
In thefluid control valve 1, the insert portion 253 of the shaft 25 is formed so that the cross-sectional shape substantially perpendicular to the rotation axis RA25 is a polygonal shape. Further, the shaft 25 has grooves 254 and 255 on both sides of the insert portion 253, the outer diameter of which is smaller than the outer diameter of the insert portion 253. Thereby, stress due to the rotational torque of the valve member 20 acts on the insert portion 253, while the springs 165, 175, and 185 of the pipes 16, 17, and 18 are in a direction substantially perpendicular to the rotational axis RA25 of the shaft 25. The stress when the force is applied acts on the grooves 254 and 255 and is dispersed. Therefore, damage to the valve member 20 can be prevented.
流体制御弁1では、シャフト25のインサート部253は回転軸RA25に略垂直な断面形状が多角形状となるよう形成されている。また、シャフト25は、インサート部253の両側には、外径がインサート部253の外径に比べ小さい溝254,255を有している。これにより、弁部材20の回転トルクによる応力はインサート部253に作用する一方、各配管16,17,18が有するばね165,175,185によるシャフト25の回転軸RA25に対して略垂直な方向の力を受けたときの応力は、溝254,255に作用し分散する。したがって、弁部材20の破損を防止することができる。 (R) Conventionally, when a shaft made of metal is inserted into a valve member made of resin, the stress of the rotational torque of the valve member and the force in a direction substantially perpendicular to the rotational axis of the shaft Since stress concentrates on the same part of the part of the valve member in which the shaft is inserted, excessive stress is applied. For this reason, there exists a possibility that a valve member may be damaged.

(S) The radiator pipe 16, the oil cooler pipe 17, and the air conditioning pipe 18 are provided in the radially inward direction of the springs 165, 175, 185, and end faces of the pipes 161, 171, 181 on the valve member 20 side and the sleeve 163. And plates 166, 176, and 186 that are in contact with the outer wall surfaces of 173 and 183 on the radially outer side. As a result, the plates 166, 176, 186 restrict the movement of the springs 165, 175, 185 in the radial direction while maintaining the inner diameters of the springs 165, 175, 185. Therefore, sliding between the springs 165, 175, 185 and the sleeves 163, 173, 183 and sliding between the springs 165, 175, 185 and the first housing 10 can be prevented.
(t)弁部材20は、第一筒部22と第二筒部23との間の第二筒部23側に窪み201を有する。これにより、第一筒部22の外壁面221に当接可能なラジエータ配管16のシート162と第二筒部23の外壁面231に当接可能なオイルクーラ用配管17のシート172及び空調用配管18のシート182とが干渉することを防止しつつ、流体制御弁1の回転軸RA25に略垂直な方向の体格をさらに小さくすることができる。

Accordingly, the seat 162 of the radiator pipe 16 that can come into contact with the outer wall surface 221 of the first cylinder part 22, the seat 172 of the oil cooler pipe 17 that can come into contact with the outer wall face 231 of the second cylinder part 23, and the air conditioning pipe. The size of the fluid control valve 1 in the direction substantially perpendicular to the rotation axis RA25 can be further reduced while preventing the 18 seats 182 from interfering.
