通路１１には絞り手段１２が設けられている。 A constricted portion 6 is formed in the spool valve 5 at a position corresponding to the inflow hole 2, and first and second tapered surfaces 13 and 14 in the shape of a truncated cone are formed on both sides of this constricted portion 6. 13,1
4 have first and second O-rings, respectively.
Sealing members 15 and 16 are arranged. on the other hand,
On the main body 1 side, first and second conical surfaces 17 and 18 corresponding to the tapered surfaces 13 and 14 are arranged to sandwich the inflow hole 2. Further, between one end of the spool valve 5 (on the right side in the figure) and the main body 1, there is a spring means 1 for pressing the spool valve 5 to the left side in the figure.
0 is placed. On the other hand, the other end of the spool valve 5 (on the left side in the figure) has its outer peripheral edge connected to approximately the center of a diaphragm 7 held by the main body 1 side. This diaphragm 7 forms a first cavity 8 and a second cavity 9 together with the main body 1 . The first empty chamber 8 (on the left side in the figure) and the first outflow hole 3 (on the left side in the figure) are communicated through a communication passage 11, and the communication passage 11 is provided with a throttle means 12.

ルブ５はバネ手段１０に向つて移動する。 The effects of the present invention will be explained based on the embodiment shown in FIG. In the state shown in FIG. 1, when fluid flows in from the inflow hole 2 side, the fluid flows out into the first outflow hole 3 through the gap between the spool valve 5 and the main body 1, and a portion of the fluid flows through the communication path 11. and flows into the first cavity 8. When the fluid pressure in the first cavity 8 overcomes the pressing force of the spring means 10, the spool valve 5 moves towards the spring means 10.

出穴４側から流出することになる。 As a result, the sealing between the second tapered surface 14 and the second conical surface 18 is broken, while the sealing between the first tapered surface 13 and the first conical surface 17 is achieved,
The fluid that was flowing out to the first outflow hole 3 side will flow out from the second outflow hole 4 side.

る。 On the other hand, when the fluid does not flow out from the first outflow hole 3, the fluid pressure in the first cavity 8 escapes to the first outflow hole 3 side via the communication path 11 and decreases. do. As a result, the spring means 10 causes the spool valve 5 to return to the state shown in the figure, and the second outflow hole 4
The fluid flowing out from the side will flow out from the first outflow hole 3 side. By repeating such an operation, it is possible to continuously switch the fluid outflow passage. Further, an arbitrary switching period can be obtained by adjusting the amount of throttling by the throttling means 12 and changing the pressing force of the spring means 10.
上述した様に、本考案は電磁弁の様な特別の作
