It is composed of a fixed lid 63 made of metal and approximately disc-shaped. The holder part 6 is fixed by welding to the upper end of the case 15 fixed to the valve body 1 via a fixed lid 63. Note that a C ring 20 that fixes the housing 5 and the valve body 1 is fitted between the upper end of the housing 5 and the fixed lid 63. The valve guide portion 61 is formed with a guide hole 61a coaxial with the axis X and having rounded corners and a prismatic cavity. The guide shaft 23, which is engaged with the hook portion 22 of the valve body 2, is inserted into the guide hole 61a.

また、固定蓋６３には、弁本体の弁室１Ａ及びケース１５の内部を密閉するキャン６４が固定されており、このキャン６４内にマグネットロータ７が収容されている。マグネットロータ７の中心にはロータ軸７１が取り付けられ、ロータ軸７１の弁体２側の外周には、弁体２に係合されたガイド軸２３の雌ねじ部２３ａに螺合する雄ねじ部７１ａが形成されている。また、このロータ軸７１はホルダ部６の軸受部６２にて支持されている。これによりマグネットロータ７は、キャン６４内で回動自在に支持されている。なお、ガイド孔６１ａの上部において、軸受部６２とロータ軸７１のフランジ部７２との間、および、マグネットロータ７と軸受部６２との間には摺動ワッシャ６６，６７が配設されている。 Further, a can 64 that seals the valve chamber 1A of the valve body and the inside of the case 15 is fixed to the fixed lid 63, and the magnet rotor 7 is housed within this can 64. A rotor shaft 71 is attached to the center of the magnet rotor 7, and a male threaded portion 71a is provided on the outer periphery of the rotor shaft 71 on the valve body 2 side to be screwed into the female threaded portion 23a of the guide shaft 23 engaged with the valve body 2. It is formed. Further, this rotor shaft 71 is supported by a bearing portion 62 of the holder portion 6. Thereby, the magnet rotor 7 is rotatably supported within the can 64. In addition, sliding washers 66 and 67 are arranged between the bearing part 62 and the flange part 72 of the rotor shaft 71 and between the magnet rotor 7 and the bearing part 62 in the upper part of the guide hole 61a. .

ステータコイル８は、樹脂製のボビン８１にコイル８２Ａ、８２Ｂを巻装することで、軸線Ｘ方向に一対のコイル部を積層して構成され、ボビン８１には、磁極歯８３ａを持つ継鉄（ヨーク）８３がモールド成形により一体に組み付けられている。また、ステータコイル８は、中央に軸線Ｘを中心とする円柱形状の嵌挿孔８Ｈを有しており、この嵌挿孔８Ｈの内周面の一部に継鉄８３の磁極歯８３ａが配置されている。そして、ステータコイル８は、嵌挿孔８Ｈ内に弁本体１のキャン６４が嵌挿されることで弁本体１に装着されている。これにより、ステータコイル８の磁極歯８３ａがキャン６４の外周面に対向配置される。 The stator coil 8 is constructed by winding the coils 82A and 82B around a resin bobbin 81 and stacking a pair of coil parts in the axis X direction. A yoke) 83 is integrally assembled by molding. Further, the stator coil 8 has a cylindrical insertion hole 8H centered on the axis X at the center, and the magnetic pole teeth 83a of the yoke 83 are arranged on a part of the inner peripheral surface of the insertion hole 8H. has been done. The stator coil 8 is attached to the valve body 1 by fitting the can 64 of the valve body 1 into the fitting hole 8H. As a result, the magnetic pole teeth 83a of the stator coil 8 are arranged to face the outer peripheral surface of the can 64.

以上の構成により、ステータコイル８のコイル８２Ａ、コイル８２Ｂへのパルス出力の印加によりコイル８２Ａ、コイル８２Ｂが磁力線を発生する。これにより、磁極歯８３ａの磁極（Ｎ、Ｓ極）が交互に変化し、マグネットロータ７に対して磁気吸引力及び磁気反発力を発生し、マグネットロータ７とロータ軸７１が回転する。これによりロータ軸７１の雄ねじ部７１ａと、弁体２に係合されたガイド軸２３の雌ねじ部２３ａとによるネジ送り機構によりこのガイド軸２３が軸線Ｘ方向に移動し、このガイド軸２３と共に弁体２が軸線Ｘ方向にスライドする。そして、図１の第１状態から図２の第２状態へ、あるいは、図２の第２状態から図１の第１状態へと、流路が切換られる。 With the above configuration, the coils 82A and 82B generate lines of magnetic force by applying pulse output to the coils 82A and 82B of the stator coil 8. As a result, the magnetic poles (N, S poles) of the magnetic pole teeth 83a change alternately, generating magnetic attraction force and magnetic repulsion force with respect to the magnet rotor 7, and the magnet rotor 7 and rotor shaft 71 rotate. As a result, the guide shaft 23 is moved in the direction of the axis X by the screw feeding mechanism formed by the male threaded portion 71a of the rotor shaft 71 and the female threaded portion 23a of the guide shaft 23 engaged with the valve body 2, and together with this guide shaft 23, the valve is opened. The body 2 slides in the direction of the axis X. Then, the flow path is switched from the first state shown in FIG. 1 to the second state shown in FIG. 2, or from the second state shown in FIG. 2 to the first state shown in FIG.

ハウジング側流路５１Ｄは、圧縮機の吐出口に接続され、高温高圧の冷媒を弁本体１の弁室１Ａに導入し、ハウジング側流路５１Ｓは、圧縮機の吸入口に接続され、圧縮機に冷媒を戻す。また、ハウジング側流路５１Ｅは、冷凍サイクルの蒸発器に連通され、ハウジング側流路５１Ｃは、冷凍サイクルの凝縮器に連通される。そして、図１の第１状態では、入口ポート１３Ｄから流入する高温冷媒は、弁室１Ａを介して第２ポート１３Ｃへ流れ、図２の第２状態では、入口ポート１３Ｄから流入する高温冷媒は、弁室１Ａを介して第１ポート１３Ｅへ流れる。 The housing-side flow path 51D is connected to the discharge port of the compressor and introduces high-temperature, high-pressure refrigerant into the valve chamber 1A of the valve body 1. The housing-side flow path 51S is connected to the suction port of the compressor and Return the refrigerant to. Moreover, the housing side flow path 51E is communicated with the evaporator of the refrigeration cycle, and the housing side flow path 51C is communicated with the condenser of the refrigeration cycle. In the first state of FIG. 1, the high-temperature refrigerant flowing from the inlet port 13D flows to the second port 13C via the valve chamber 1A, and in the second state of FIG. , flows to the first port 13E via the valve chamber 1A.

以上のように、「付勢部材」としての板バネ３は、弁体２におけるシール部２Ｂとは反対側の頂部に取り付けられる基部３１（取付部）と、基部３１から軸線Ｘ方向と交差する交差面内に沿って径方向の外側に延びる延出部３２と、延出部３２の先端に設けられて弁本体１の内周面に接触可能な接触部３３と、を有している。したがって、弁体２の頂部から弁座面４Ａの側に付勢力を付与することができる。またスライド方向に対し交差して弁本体１の内周面に接触しているので、弁体のスライド方向の違いによる付勢力のばらつきを抑制することができるとともに、板バネ３の先端が弁本体１の内周面に引っ掛かりにくくできる。このため、弁体２のシール部２Ｂが、弁座部材４の弁座面４Ａを押圧する荷重を安定させることができて、シール部２Ｂと弁座面４Ａとの摺動抵抗も安定するので、弁体２と弁座部材４との良好な作動性とシール性を得ることができる。また、必要以上にアクチュエータを大型化する必要がなく、アクチュエータを小型化することができる。なお、本体１の内周面の接触部３３が接触する部位は、弁座面４Ａに対し平行な平面で形成されると、弁体２の作動時における板バネ３の付勢力の変化を抑制できるので好ましい。 As described above, the leaf spring 3 as a "biasing member" is attached to the base 31 (attachment part) attached to the top of the valve body 2 on the opposite side from the seal part 2B, and the base 31 intersects with the axis X direction from the base 31. It has an extending portion 32 extending radially outward along the intersecting plane, and a contact portion 33 provided at the tip of the extending portion 32 and capable of contacting the inner circumferential surface of the valve body 1. Therefore, a biasing force can be applied from the top of the valve body 2 to the valve seat surface 4A side. In addition, since it crosses the sliding direction and contacts the inner circumferential surface of the valve body 1, variations in the biasing force due to differences in the sliding direction of the valve element can be suppressed, and the tip of the leaf spring 3 contacts the inner circumferential surface of the valve body 1. It is difficult to get caught on the inner peripheral surface of 1. Therefore, the seal portion 2B of the valve body 2 can stabilize the load pressing against the valve seat surface 4A of the valve seat member 4, and the sliding resistance between the seal portion 2B and the valve seat surface 4A is also stabilized. , good operability and sealing performance between the valve body 2 and the valve seat member 4 can be obtained. Further, there is no need to make the actuator larger than necessary, and the actuator can be made smaller. Note that if the portion of the inner circumferential surface of the main body 1 that the contact portion 33 comes into contact with is formed in a plane parallel to the valve seat surface 4A, changes in the biasing force of the leaf spring 3 when the valve body 2 is actuated are suppressed. This is preferable because it can be done.

また、この実施形態では、板バネ３（付勢部材）の延出部３２は、基部３１（取付部）に接続される基端部３２ａと、基端部３２ａから折り返して反対側に延びる折返部３２ｂと、を有している。そして、折返部３２ｂの先端に接触部３３が設けられている。このように、延出部３２が基端部３２ａと折返部３２ｂとを有した「くの字状」に形成されているので、「くの字」の高さや延出部３２の長さを変えることにより、弁体２に付与する押圧荷重を調整しやすくなる。また、板バネ３は、基部３１（取付部）と、延出部３２および接触部３３とが一体に形成されている。したがって、板ばね３の小型化が可能となる。なお、本形態では、板バネ３は、基部３１と、延出部３２および接触部３３とが一体に形成されているが、基部３１と、延出部３２および接触部３３とを別部材として、板状の基部３１の上に延出部３２を溶接等で固定してもよい。また、板バネ３の接触部３３は、弁本体１の内周面に向かって凸な球面状に形成されている。このように、接触部３３が球面状に形成されているので、接触部３３が弁本体１の内周面に当接されスライド方向に移動する際、更に引っ掛かりにくくなる。また、弁本体１の内周面に当接した球面状の凸の中心は、弁体２のシール部２Ｂにおける軸線中心線上に位置するように形成すると、弁体２の頂部からシール部２Ｂに対して垂直に押圧荷重を付与しやすいので、シール部２Ｂ全面に均一な押圧荷重が付与され、弁体２と弁座部材４との更に良好な作動性とシール性が得られ好ましい。なお、本形態では接触部３３は、弁本体１の内周面に向かって凸な球面状に形成されているが、本体１の内周面に向かって凹部、または開口部を形成し、該凹部や開口部にＳＵＳ等の球を固定して、球の球面を接触させると、弁本体１の内周面との摺動抵抗が更に小さくなり好ましい。 In this embodiment, the extending portion 32 of the leaf spring 3 (biasing member) includes a base end portion 32a connected to the base portion 31 (attachment portion), and a folded portion extending from the base end portion 32a to the opposite side. It has a portion 32b. A contact portion 33 is provided at the tip of the folded portion 32b. In this way, since the extending part 32 is formed in a "dogleg" shape having the base end 32a and the folded part 32b, the height of the "dogleg" and the length of the extending part 32 can be adjusted. By changing, the pressing load applied to the valve body 2 can be easily adjusted. Further, the leaf spring 3 includes a base portion 31 (attachment portion), an extension portion 32, and a contact portion 33 that are integrally formed. Therefore, the leaf spring 3 can be made smaller. In addition, in this embodiment, the base 31, the extension part 32, and the contact part 33 are integrally formed in the leaf spring 3, but the base 31, the extension part 32, and the contact part 33 are formed as separate members. , the extending portion 32 may be fixed onto the plate-shaped base 31 by welding or the like. Further, the contact portion 33 of the leaf spring 3 is formed into a spherical shape that is convex toward the inner circumferential surface of the valve body 1. Since the contact portion 33 is formed in a spherical shape in this manner, when the contact portion 33 comes into contact with the inner circumferential surface of the valve body 1 and moves in the sliding direction, it becomes more difficult to get caught. Furthermore, if the center of the spherical convexity that abuts the inner peripheral surface of the valve body 1 is formed to be located on the axis center line of the seal portion 2B of the valve body 2, the center of the spherical convexity that is in contact with the inner circumferential surface of the valve body 1 can be formed from the top of the valve body 2 to the seal portion 2B. Since it is easy to apply a pressing load perpendicularly to the seal portion 2B, a uniform pressing load can be applied to the entire surface of the seal portion 2B, and better operability and sealing performance between the valve body 2 and the valve seat member 4 can be obtained, which is preferable. Note that in this embodiment, the contact portion 33 is formed in a spherical shape that is convex toward the inner circumferential surface of the valve body 1; It is preferable to fix a ball made of SUS or the like in the recess or opening and bring the spherical surface of the ball into contact with the inner peripheral surface of the valve body 1, since the sliding resistance with the inner circumferential surface of the valve body 1 is further reduced.

また、板バネ３の接触部３３は、軸線Ｘ方向に沿って複数箇所（２カ所）に設けられている。このように、接触部３３が複数設けられているので、接触部３３の１箇所当たりに必要とされる押圧荷重が小さくなる。したがって、板バネ３の薄板化が可能となるとともに、シール部２Ｂと弁座面４Ａ、接触部３３と弁本体１の内周面との摺動抵抗性が小さくなり、各摺動面における摩耗を抑制できる。また、板バネ３の基部３１（取付部）は、軸線Ｘ方向に延びる板状に形成され、その中央部１箇所で前記弁体２に固定されている。そして弁体２には、基部３１の側端縁に当接して回転を規制する規制部２１ｂが設けられている。このように、基部３１が軸線Ｘ方向に延びる板状に形成されているので、弁体２との設置面積を大きくすることができるので、シール部２Ｂ全面に均一に押圧荷重を付与できる。また、規制部２１が設けられているので、弁体２が作動しても板バネ３はずれることがない。 Further, the contact portions 33 of the leaf spring 3 are provided at a plurality of locations (two locations) along the axis X direction. In this way, since a plurality of contact portions 33 are provided, the pressing load required for each contact portion 33 is reduced. Therefore, the plate spring 3 can be made thinner, and the sliding resistance between the seal portion 2B and the valve seat surface 4A, and between the contact portion 33 and the inner circumferential surface of the valve body 1 is reduced, resulting in wear on each sliding surface. can be suppressed. Further, the base portion 31 (attachment portion) of the leaf spring 3 is formed into a plate shape extending in the direction of the axis X, and is fixed to the valve body 2 at one location in the center thereof. The valve body 2 is provided with a regulating portion 21b that comes into contact with the side edge of the base portion 31 to regulate rotation. In this way, since the base portion 31 is formed into a plate shape extending in the direction of the axis X, the installation area with the valve body 2 can be increased, so that a pressing load can be uniformly applied to the entire surface of the seal portion 2B. Furthermore, since the regulating portion 21 is provided, the leaf spring 3 will not be dislocated even if the valve body 2 is actuated.

図６は実施形態のスライド式切換弁における変形例の板バネ（摺接部材）の平面図、Ａ－Ａ相当断面図及び弁体の平面図である。この変形例では弁体２の頂部に「付勢部材」としての板バネ９を備えている。板バネ９は、弁体２におけるシール部２Ｂとは反対側の頂部に取り付けられる「取付部」としての基部９１と、基部９１から軸線Ｘ方向と交差する交差面内に沿って径方向の外側に延びる二対（４組）の延出部９２と、延出部９２の先端に設けられて弁本体１の内周面に接触可能な凸状の二対（４組）の接触部９３と、を有している。また、板バネ９の基部９１の軸線Ｘ方向の中央には、取付け孔９４が形成されている。そして、基部９１の中央部１箇所の取付け孔９４にボス部２１ａが係合され、接触部９３を弁本体１の内周面に当接させることにより生じる延出部９２の弾性力で、板バネ９（基部９１）が弁体２の頂部に固定されるとともに、弁体２のシール部２Ｂは弁座部材４の弁座面４Ａに押圧される。この変形例では、板バネ９の二対（４組）の延出部９２が軸線Ｘに対して対称な位置に形成されているので、４つの接触部９３が弁本体１の内周面に均等な位置で接触することができ、弁体２の姿勢を安定させることができる。 FIG. 6 is a plan view of a leaf spring (sliding member) of a modified example of the slide type switching valve of the embodiment, a sectional view corresponding to AA, and a plan view of a valve body. In this modification, a leaf spring 9 is provided at the top of the valve body 2 as a "biasing member". The leaf spring 9 has a base 91 as a "mounting part" attached to the top of the valve body 2 on the opposite side to the seal part 2B, and a radially outer side along an intersecting plane intersecting the axis X direction from the base 91. two pairs (four sets) of extension portions 92 extending from the top of the valve body 1, and two pairs (four sets) of convex contact portions 93 provided at the tips of the extension portions 92 and capable of contacting the inner circumferential surface of the valve body 1. ,have. Further, a mounting hole 94 is formed in the center of the base 91 of the leaf spring 9 in the axis X direction. Then, the boss portion 21a is engaged with the mounting hole 94 at one location in the center of the base portion 91, and the elastic force of the extending portion 92 generated by bringing the contact portion 93 into contact with the inner circumferential surface of the valve body 1 causes the plate to The spring 9 (base 91) is fixed to the top of the valve body 2, and the seal portion 2B of the valve body 2 is pressed against the valve seat surface 4A of the valve seat member 4. In this modification, two pairs (four sets) of the extension portions 92 of the leaf spring 9 are formed at symmetrical positions with respect to the axis X, so that four contact portions 93 are formed on the inner circumferential surface of the valve body 1. Contact can be made at even positions, and the posture of the valve body 2 can be stabilized.
