8, when the solenoid 17 is energized, the valve body 16 moves forward against the elastic force of the spring 18,
Further, when the energization to the solenoid 17 is cut off, the valve body 16 retreats due to the restoring resiliency of the spring 18, thereby alternately switching between the positive pressure tank 3 and the negative pressure tank 4 as described above.

次に、本発明の特徴部分について説明すると、
これら三方電磁切換弁１２，１３は剛性連結部材
１９を介して互いに連結されている。三方電磁切
換弁１２，１３を剛性連結部材１９に固定する手
段は、図示しないがネジ止め、接着剤等が使用さ
れる。 Next, the characteristic parts of the present invention will be explained.
These three-way electromagnetic switching valves 12 and 13 are connected to each other via a rigid connection member 19. The means for fixing the three-way electromagnetic switching valves 12 and 13 to the rigid connecting member 19 is not shown, but screws, adhesives, etc. are used.
三方電磁切換弁１２，１３は、動作時の振動に
より互いに衝突しない程度であつてそれぞれから
発生する振動が剛性連結部材１９で干渉し合う程
度まで接近して配置されている。 The three-way electromagnetic switching valves 12 and 13 are arranged so close that they do not collide with each other due to vibrations during operation, but close enough that the vibrations generated from each interfere with each other at the rigid connecting member 19.
また、三方電磁切換弁１２，１３の弁体１６，
１６の往復動距離、速度、重量はほぼ等しく設定
され、また弁体１６，１６の配列方向は同じ方向
に設定されている。また、動作時における弁体１
６，１６の移動方向は互いに反対となつている
（第２図に示す実線及び点線の矢印参照）。 In addition, the valve body 16 of the three-way electromagnetic switching valve 12, 13,
The reciprocating distance, speed, and weight of the valve bodies 16 are set to be approximately equal, and the valve bodies 16 and 16 are arranged in the same direction. In addition, the valve body 1 during operation
The moving directions of 6 and 16 are opposite to each other (see solid line and dotted line arrows shown in FIG. 2).
したがつて、三方電磁切換弁１２，１３を高速

ほどズレており、さらに配列方向が同じであるこ
とから伝搬方向も同じとなり、剛性連結部材１９
に伝達されたとき、該剛性連結部材１９で互いに
打ち消し合うことになる。 Therefore, even if the three-way electromagnetic switching valves 12 and 13 are switched at high speed, the vibrations generated at this time have approximately the same amplitude and period because the reciprocating distance, speed, and weight of the valve bodies 16 and 16 are approximately equal. Since the moving directions are the same, and the moving directions are opposite, the phase is shifted by approximately half a period.Furthermore, since the arrangement direction is the same, the propagation direction is also the same, and the rigid connecting member 19
When the signals are transmitted to the rigid connecting member 19, they cancel each other out.
なお、弁体１６，１６の往復動距離、速度及び
重量が等しくない場合でも、弁体１６，１６の移
動方向が互いに反対であり、配列方向が同じであ
れば、上述の実施例ほどではないが、剛性連結部
材１９で振動が互いに打ち消され、振動を減ずる
ことができる。 Note that even if the reciprocating distance, speed, and weight of the valve bodies 16, 16 are not equal, if the moving directions of the valve bodies 16, 16 are opposite to each other and the arrangement directions are the same, the effect will not be as great as in the above embodiment. However, the vibrations are canceled out by the rigid connecting member 19, and the vibrations can be reduced.
前述の三方電磁切換弁１２，１３の空気出入口
が互いに接続されるような場合には、第３図に示
すように剛性連結部材１９としてマニホールドを
使用することができる。これにより、更に剛性を
高め、かつ小型化することができる。 When the air inlets and outlets of the three-way electromagnetic switching valves 12 and 13 are connected to each other, a manifold can be used as the rigid connecting member 19, as shown in FIG. Thereby, the rigidity can be further increased and the size can be reduced.

に吸引される。 FIG. 4 shows a case where electromagnetic on-off valves 20 and 21 are used. In this embodiment, the electromagnetic on-off valve 2
0 and 21 open alternately, and when one electromagnetic on-off valve 20 opens, pressurized air is supplied from the positive pressure tank 3' to the blood pump 5, and when the other electromagnetic on-off valve 21 opens, the blood pump 5 Air from negative pressure tank 4
is attracted to.
これら電磁開閉弁２０，２１は、第５図に示す

１９で打ち消し合うことになる。 As shown in FIG. 5, these electromagnetic on-off valves 20, 21 are connected to each other by a rigid connecting member 19, the valve bodies 22, 22 are arranged in the same direction, and the valve bodies 22, 22 are arranged in the same direction during operation. The directions of movement are opposite to each other. Vibrations generated during operation are canceled out by the rigid coupling member 19, as in the previous embodiment.

動装置にも適用できる。 In both of the above embodiments, the case where two solenoid valves are connected is shown, but the invention is not limited to this, and it is sufficient if a plurality of solenoid valves are connected. They should cancel each other out. In addition, although we have shown a case in which positive pressure and negative pressure are applied alternately, drive devices that apply only positive pressure (the atmosphere is the source of negative pressure) or only negative pressure (the atmosphere is the source of positive pressure) can also be used. applicable. In addition, it is not limited to blood pumps,
For example, it can be applied to a driving device for a respirator or an intra-aortic balloon pump.

らなくてもすみ、コストアツプとならない。 As explained above, according to the present invention, the vibrations generated during the operation of each electromagnetic valve are canceled out by the connecting member (rigid connecting member 19).
Vibration and noise can be reduced as much as possible, and the special feature is that the valve bodies are aligned in the same direction, and the movement direction of the valve bodies during operation is reversed, bringing them close together so that the vibrations interfere with each other. This eliminates the need for a vibration-proof structure, and does not increase costs.
