Wrong, to open and close the fluid path, and switch the flow direction. For example, in the refrigerating cycle (cy c 1 e), compared with Bai Zhi, in order to open and close the refrigerant passage to switch the flow direction, such a solenoid valve is provided in the middle of the refrigerant circulation pipe. ^ In the above solenoid valve, the valve body is instantly attracted by applying a predetermined set voltage to the solenoid officer '. For this reason, the valve body has a tendency to collide with the attractor '. For example, a distance of 5 cm (cm) from the solenoid valve causes a relatively large collision sound of n decibels (dB'A). In particular, such as refrigeration ^^ ", the device installed in the house, the collision sound of the valve body is very harsh, so I hope to make it silent. Therefore, it is an object of the present invention to provide a solenoid valve which can make the generated sound very small when the valve body collides with the attractor. [Mechanism for Solving the Problem] The solenoid valve of the first patent application scope of the present invention is provided with the following: a valve body; the first and second suction devices are provided with: a valve chamber is formed in the valve body; and There is a gap in the axial direction; the valve body is via a spring mechanism

Description of the invention (9X i (mm) ", the valve body 27 is located at an equidistant position from the first suction device and the second suction device 14 and 15 (hereinafter, the middle position). Also," 0.4 mm "" Is the ball 3 0 of the valve body 2 7 shown in the state of being in close contact with the valve seat 26. When "0.4 to 0 mm", the ball 3 0 gradually falls into the valve body 27, so that The valve body 2 7 is close to the first attractor 14. Therefore, when "0 mm", the valve body 27 and the first attractor 14 are almost completely tightened. '
又，彈簧力，是第1及第2線圈彈簧2 8及2 9、滾珠所用線 圈彈簧32之合成彈簧力，其用直線A來表示。又，上述磁 力，是藉著永久磁鐵34及螺線管1 7並在磁化之第1吸引器 1 4和閥體2 7之間起作用的合成磁力，其是以曲線B 1〜B 7來 表示。尚且，曲線B1〜B7是各別表示上述螺線管1 7施加電 壓之大小是0、2、4、6、8、1 0、1 2伏特（V)時之合成磁 力。所以，在本實施例，如圖4所示，表示彈簀力之直線A 斜率，是採用比表示磁力之曲線B1〜B7斜率大之線圈彈簧 如上述般，閥體27之構造，是藉著第1及第2線圈彈簧28 及29來保持中間位置。為此，如果閥體27是朝著靠近第1 吸引器1 4之方向來移動（即，如果閥體2 7位置是靠近 「0」），是與其移動量呈比例並能將閥體2 7拉回中間位置 之力量起作用。因此，隨著閥體2 7位置靠近「0」來使彈 簧力變大。 另一方面，在第1吸引器1 4和閥體2 7之間起作用之磁 力，是與第1吸引器1 4和閥體2 7之距離的2次方呈反比例。 又，在第1吸引器1 4和閥體2 7之間起作用之磁力，是依照The spring force is the combined spring force of the first and second coil springs 28 and 29 and the coil spring 32 for the ball, and it is represented by the straight line A. The above-mentioned magnetic force is a combined magnetic force acting between the magnetized first attractor 14 and the valve body 27 through the permanent magnet 34 and the solenoid 17, and it is based on the curves B 1 to B 7 Means. In addition, the curves B1 to B7 indicate the combined magnetic forces when the magnitude of the voltage applied to the solenoid 17 is 0, 2, 4, 6, 8, 10, and 12 volts (V), respectively. Therefore, in this embodiment, as shown in FIG. 4, the slope of the straight line A representing the elastic force is a coil spring having a slope greater than that of the curves B1 to B7 representing the magnetic force. As described above, the structure of the valve body 27 is obtained by The first and second coil springs 28 and 29 maintain an intermediate position. For this reason, if the valve body 27 is moved toward the first suction device 14 (that is, if the position of the valve body 27 is close to "0"), it is proportional to the amount of movement and the valve body 27 can be moved. The force pulling back to the middle position works. Therefore, as the position of the valve body 27 approaches "0", the spring force becomes larger. On the other hand, the magnetic force acting between the first attractor 14 and the valve body 27 is inversely proportional to the power of the distance between the first attractor 14 and the valve body 27. The magnetic force acting between the first attractor 14 and the valve body 27 is in accordance with
第12頁 五、發明說明（10〕 . 施加於螺線管1 7之電壓大小來變大。此時，因為表示上述 彈簧力之直線A斜率，是比表示磁力之曲線B1〜B7的斜率 大，如圖4所示，直線A是與曲線B 1〜B 7交叉。該交叉點 (在圖4是以C1〜C7來表示）是表示彈簣力和磁力是維持平 衡。例如，施加電壓是8 V時，閥體2 7是從第1吸引器1 4在 位於0. 2 m m之處時，磁力和彈簧力是維持平衡。 又，為了使閥體27與第1吸引器1 4緊密接合’所必須之 施加電壓，即設定電壓，依照圖4是變成1 2 V。但是，如果 在瞬間將施加電壓立即上昇到1 2 V時，為了使閥體2 7順利 地移動到第1吸引器14，閥體27是有與第1吸引器14相撞之 趨勢，其結果，是產生較大之聲音。 相對於此，首先，如果在螺線管1 7施加2 V電壓，磁力是 在超過彈簧力之交叉點C2位置移動閥體27。所以，如果閥 體27是到達交叉點C2位置，為了使磁力和彈簧力維持平衡 而在其位置保持閥體。其次，如果螺線管1 7之施加電壓是 提昇到4V，為了再次使磁力超過彈簧力，閥體2 7，是移動 到直線A和曲線B 3之交叉點C 3位置。以下，相同地藉著使 施加電壓依序提昇到1 2 V，是能使閥體2 7移動到下個交叉 點，最後，閥體27是與第1吸引器1 4緊密接合。 & 即，如果依照位置而作用於閥體2 7之彈簣力是稍微超過 磁力，來漸漸提昇螺線管1 7之施加電壓，換言之，如果施 加電壓是使變成達到1 2V之立即上升時間T1變長，闊體27 是漸漸地抗拒彈簧力並且朝著第1吸引器1 4方向移動。 另一方面，如果立即上升時間T1是過長，消耗電力是變Page 12 V. Description of the invention (10). The voltage applied to the solenoid 17 increases. At this time, the slope of the straight line A representing the spring force is larger than the slope of the curve B1 to B7 representing the magnetic force. As shown in Figure 4, the straight line A intersects the curves B 1 to B 7. This intersection (represented by C1 to C7 in Figure 4) indicates that the spring force and magnetic force are maintained in balance. For example, the applied voltage is At 8 V, the valve body 27 is maintained at a position of 0.2 mm from the first attractor 14, and the magnetic force and the spring force are maintained in balance. In addition, the valve body 27 and the first attractor 14 are tightly engaged. 'The required applied voltage, that is, the set voltage, becomes 12 V according to Fig. 4. However, if the applied voltage is immediately increased to 12 V at an instant, in order to smoothly move the valve body 27 to the first attractor 14. The valve body 27 tends to collide with the first attractor 14. As a result, a louder sound is generated. In contrast, first, if a voltage of 2 V is applied to the solenoid 17, the magnetic force will exceed The position of the cross point C2 of the spring force moves the valve body 27. Therefore, if the valve body 27 reaches the position of the cross point C2, The magnetic force and the spring force maintain balance and maintain the valve body in its position. Secondly, if the applied voltage of the solenoid 17 is raised to 4V, in order to make the magnetic force exceed the spring force again, the valve body 27 is moved to the straight line A and the curve The position of the intersection point C 3 of B 3. Hereinafter, the valve body 27 can be moved to the next intersection point by sequentially increasing the applied voltage to 12 V in the same manner. Finally, the valve body 27 is attracted to the first The device 14 is tightly coupled. That is, if the repulsive force acting on the valve body 2 7 according to the position is slightly more than the magnetic force, the applied voltage of the solenoid 17 is gradually raised, in other words, if the applied voltage is such that The immediate rise time T1 of 1 2V becomes longer, and the wide body 27 gradually resists the spring force and moves in the direction of the first attractor 14. On the other hand, if the immediate rise time T1 is too long, the power consumption changes.

Description of the invention (there is too much I, and the solenoid 17 generates heat and has the disadvantages of temperature rise. Here, in this embodiment, the above-mentioned immediate rise time τ 丨 is set to about 5 seconds. If by invention In the investigation, when the immediate rise time T1 is 5 seconds, the sound generated by the valve body 27 when it collides with the first attractor 14 is about 50 centimeters (cm) from the solenoid valve 12. ~ 60 dB (A) can be suppressed to be smaller than the conventional 80 ~ 90 dB (A). In addition, here, the case where the valve body 27 moves toward the first attractor 14 is explained. This is the same as the case of moving in the direction of the second suction device 15.
其f，是參考圖6來說明上述構造之作用。首先，在初 期狀態，如圖6 ( a)所示，閥體27是與第2吸弓丨哭 合者。此時，沒有在螺線管17施加電壓，藉著σ久磁^ 之磁力來保持第2吸引器15和閥體27 。2 藉著永久磁賴並以箭頭咖來表示接所。產= 現在，如果壓縮機2是在運糙由， 引器1 5緊密接合，經由入口管曰者間體27是與第2吸 媒，該冷媒是從冷凝器3提供自冷嘁器3之冷 通管道23經由旁通用冷媒流通其Ί 内，是從第1出口旁 F蒸發器7。 s迢1 0來提供給毛細管1 1、 在§亥狀態，如果R蒸發器所、拉 是超過設定溫度時，控制裝置/皿3又感測器38之檢測溫度 壓施加於螺線管1 7。此時，在疋^制驅動電路4 2來將電 流動著產生以箭頭Q1所表示#、，官17，是構成在圖6(b) 如，是施加如圖5 ( a )所示之、方向的電流流向，例 <凌形電壓。為此，藉著如圖The function f is described with reference to FIG. 6. First, in the initial state, as shown in Fig. 6 (a), the valve body 27 is the one who cries with the second suction bow. At this time, no voltage is applied to the solenoid 17, and the second attractor 15 and the valve body 27 are held by the magnetic force of σjiu. 2 The pick-up is indicated by a permanent magnet and an arrow coffee. Production = Now, if the compressor 2 is running, the introducer 15 is tightly connected, and the intermediary body 27 is connected to the second suction medium through the inlet pipe, and the refrigerant is provided from the condenser 3 to the self-cooler 3 The cold-pass pipe 23 circulates through the general refrigerant through the bypass refrigerant, and passes from the first outlet F evaporator 7. s 迢 1 0 to provide to the capillary 1 1. In the state of §11, if the temperature of the R evaporator exceeds the set temperature, the control device / plate 3 and the sensor 38 detect the temperature and pressure is applied to the solenoid 1 7 . At this time, the driving circuit 42 is controlled to generate a current as indicated by the arrow Q1, and the officer 17 is constituted as shown in FIG. 6 (b). For example, as shown in FIG. 5 (a), Direction of current flow, for example < Ling-shaped voltage. To do this, as shown in the figure
五、發明說明_ ~ ~〜- 所示之永久磁場34，在所產生之磁場pi、？2内，通過 日吸弓丨器14之磁場pi是強磁場，而通過第2吸引器丨5之磁 =Ρ2是弱磁場。其結果，閥體27是朝箸第1吸引器14 移動。 此日11 ’為了將施加電壓變成達到1 2 V之立即上昇時門τ 1 :定：約5秒，閥體27是漸漸.地朝著第i吸引器14方；;移 動、所以，如果施加電壓是到達1 2V，閥體27是與第i吸引 器Η緊密接合。又，施加電壓，依舊是12v並維持 id 約1秒後，才關閉（of f)。 於是’在電磁閥1 2 ’再以產生經由永久磁鐵34之箭頭 P1、。2方向之磁場，如圖6 (c)所示，閥體2 7是保持與第1吸 引器1 4緊密接合狀態。其結果，是隔斷第1吸引器^之通 ，閥室16内之冷媒是從第2出口管道24經由冷媒流通 管道9來提供給r蒸發器6及f蒸發器7。 匕 所以’如果R蒸發器所用溫度感測器38之檢測溫度是低 於設定溫度時，控制裝置35是控制驅動電路42來將電壓施 加於螺線管17。此時，在螺線管17 ,使閥體27朝著第i吸 引器14方向移動時之逆向電壓，即，是施加如圖5(b) 之波形電壓。因此，是產生如圖6(d)所示之以箭頭Q2來表 不之磁場方向。為此，藉由永久磁鐵34在所產生之磁場、 内通過第1吸引器1 4之磁場P 1是弱磁場，而通過 ^吸引器15之磁場？2是強磁場。其結果，閥體27是朝著 第2吸引器1 5方向移動。 此日守也是將電壓之立即上昇時間τ丨設定成約5秒，因V. Description of the invention The permanent magnetic field 34 shown in _ ~~~-is shown in the generated magnetic field pi? In 2, the magnetic field pi passing through the solar attractor 14 is a strong magnetic field, and the magnetic field passing through the second attractor 5 = P2 is a weak magnetic field. As a result, the valve body 27 moves toward the first suction device 14. On this day 11 'in order to change the applied voltage to an immediate rise of 1 2 V, the gate τ 1 is set: about 5 seconds, the valve body 27 is gradually. The ground is toward the i-th attractor 14; move, so if applied The voltage reaches 12V, and the valve body 27 is tightly engaged with the i-th attractor Η. In addition, after applying the voltage, it is still 12v and maintained for about 1 second before turning off (of f). Then, the arrow P1 via the permanent magnet 34 is generated at the solenoid valve 1 2 '. As shown in Fig. 6 (c), the magnetic field in the two directions keeps the valve body 27 in tight contact with the first attractor 14. As a result, the first suction device ^ is blocked, and the refrigerant in the valve chamber 16 is supplied to the r evaporator 6 and the f evaporator 7 from the second outlet pipe 24 through the refrigerant circulation pipe 9. Therefore, if the temperature detected by the temperature sensor 38 used in the R evaporator is lower than the set temperature, the control device 35 controls the driving circuit 42 to apply a voltage to the solenoid 17. At this time, the reverse voltage when the solenoid 17 moves the valve body 27 in the direction of the i-th attractor 14, that is, the waveform voltage shown in Fig. 5 (b) is applied. Therefore, a magnetic field direction indicated by an arrow Q2 as shown in Fig. 6 (d) is generated. Therefore, the magnetic field P 1 passing through the first attractor 14 through the generated magnetic field by the permanent magnet 34 is a weak magnetic field, and the magnetic field passing through the attractor 15? 2 is a strong magnetic field. As a result, the valve body 27 moves in the direction of the second suction device 15. On this day, the immediate rise time τ 丨 of the voltage is also set to about 5 seconds, because
五、發明說明（13) i此’閥體27疋漸漸地朝著第2吸引器i 5方向移動。所以， 螺線管17之施加電壓是到達12V，如果閥體27是與第2吸引 器15緊f接合，其電壓是維持約i秒後才關閉。 如果藉由如此之實施例，將螺線管1 7之施加電壓的立即 上昇時間T1設定成5秒，因為是構成將閥體27比較緩慢地 朝著第1及第2吸引器丨4及丨5方向移動，是能將閥體2 7和第 1或疋苐2吸引态1 4或是1 5之相撞聲抑制到很小。5. Description of the invention (13) iThis' valve body 27 疋 gradually moves in the direction of the second attractor i 5. Therefore, the voltage applied to the solenoid 17 reaches 12V, and if the valve body 27 is tightly engaged with the second attractor 15, the voltage is maintained for about i seconds before closing. If this embodiment is used, the immediate rise time T1 of the applied voltage of the solenoid 17 is set to 5 seconds, because the valve body 27 is relatively slowly moved toward the first and second attractors 丨 4 and 丨The movement in the 5 direction can suppress the collision between the valve body 27 and the first or 吸引 2 attracting state 1 4 or 15 to a minimum.
尚且’在本實施例，是構成：藉由永久磁鐵3 4所產生之 磁場，而沒有將電壓施加到螺線管1 7，亦是能使閥體2 7保 持與第1、第2吸引器1 4、1 5緊密接合狀態。為此，僅在切 換冷媒之流動方向時，即，僅在使閥體27移動時，最好是 在螺線管1 7施加電壓，並能謀求省電力化。 可是，如果出口管道23、24是朝著與閥體27移動方向相 同之方向延伸來設置第1及第2吸引器1 4及1 5，電磁閥1 2全 體輛方向尺寸是變長。但是’在本實施例，因為第1、第2 出ΰ管道23、24是與閥體27之移動方向正交而設置在閥主 丨肢1 3之外周緣面，_是能將電磁閥1 2之構造縮小來解決。In addition, in this embodiment, it is constituted that the magnetic field generated by the permanent magnet 34 is used without applying a voltage to the solenoid 17, and the valve body 27 can also be maintained with the first and second attractors. 1 4 and 1 5 tightly joined. For this reason, it is preferable to apply a voltage to the solenoid 17 only when the flow direction of the refrigerant is switched, that is, only when the valve body 27 is moved, and the power can be saved. However, if the outlet ducts 23 and 24 are extended in the same direction as the direction in which the valve body 27 is moved to provide the first and second attractors 14 and 15, the solenoid valve 12 will have a longer overall dimension. However, in this embodiment, because the first and second outlet pipes 23 and 24 are orthogonal to the moving direction of the valve body 27 and are provided on the outer peripheral surface of the valve main limb 1 3, _ is the electromagnetic valve 1 The structure of 2 is reduced to solve.

Description of the invention (15) '~ --- ~-It is constructed as follows: Connect the outlet pipe 51 to the peripheral surface of the valve body 丨 3. In this case, the overall size of the solenoid valve can be shortened. In the first and second embodiments described above, the person J can also borrow the permanent magnet 34 without applying a voltage to the solenoid 17 to keep the valve body 27 attracted to the first and second parts 2 1 4 and 1 5 The tightly joined state is used to describe the so-called self-holding solenoid valve. In contrast, in the third embodiment shown in FIGS. 12 and 13, the electromagnetic valve 61 having a permanent magnet for self-holding can also suppress the collision noise to a small extent. That is, in the solenoid valve 6 丨, only the valve body 27 and the i-th attractor are provided with a coil spring 62 as a spring mechanism. So in °. When the solenoid valve 17 is energized, it is electrically resistive to the coil spring 62 to make the valve body 27 attract the first attractor 丨 4, and in terms of the spring force for opening the air passage, the solenoid When the power supply 17 is not energized, the spring force 15a of the valve body 27 is rebounded and tightly engaged with the second attractor 15 by using the coil spring a. That is, the paths 15a are opened and the paths are electrically sealed. It is green, 17-way.

Moreover, in this embodiment, it is explained that the solenoid valve composed of a two-way valve is the same as in the case of a three-way valve. It is the same. In the third embodiment described above, the housing 33 can be omitted. Furthermore, in the first and second embodiments described above, the structure is such that the first and second attractors 1 are borrowed from the permanent magnet 34. The magnetic pole strengths generated by 4 and 15 become approximately equal. However, when the magnetic pole strengths generated by the first and second attractors 14 and 15 are not equal, the valve body is adjusted by adjusting the applied voltage. 2 7 to move. In addition, the 'permanent magnet 34 is preferably configured such that the end of the housing 33 side is an S pole, and the end of the valve main body 13 side is an N pole. Moreover, the present invention is not limited to the above. Examples, for example, are generally applicable to valves installed in other fluid paths that are not limited to the freezing cycle, and can be implemented without departing from the gist of the invention.
