間面積は大きくなり、連通孔を流れる流量が増大する。With the above arrangement, the movable iron core driven by the drive force generating means and the control valve element disposed at the tip of the movable iron core are lifted off by passing an electric current, and detached from the valve seat. A flow is generated from the communication hole to the outflow path side, whereby the pressure in the pressure chamber becomes lower than that of the inflow side, whereby the main valve is separated from the main valve seat, and a flow is generated from the main valve portion to the outflow side. When the current value is further increased, the control valve body is lifted to increase the clearance area, and the flow rate flowing through the communication hole increases.

The gap area formed by the needle valve element 6 and the valve seat 8 increases as the stroke of the plunger 7 increases.

座１７から流出側へ流れが生じる（図３）。As a result, the pressure supplied to the pressure chamber 14 from the bleed hole 16 of the diaphragm 11 is released to the outflow side, so that the pressure in the pressure chamber decreases, and the diaphragm 11 is lifted by the pressure difference from the inflow side. Thus, a flow is generated from the valve seat 17 to the outflow side (FIG. 3).

（図４）。When the current value is further increased, the plunger 7 is further sucked toward the pole core 2, the needle valve 6 is lifted to increase the clearance area, and the flow rate from the pressure chamber 14 to the outflow side through the communication hole 9 increases. Since the pressure in the main valve pressure chamber 14 decreases and the lift amount of the diaphragm 11 increases, the flow rate from the main valve seat 17 to the outflow side also increases (FIG. 4).

することができる。In this embodiment, the clearance area between the control valve and the valve seat, which is provided in the middle of the communication hole communicating the pressure chamber with the outflow side, is disposed at the rear of the plunger, and biases the plunger in the pushing direction. In order to control the combined force of the spring force to be applied and the force acting from the valve hole of the control valve portion by the driving force generated by the driving force generating means, even if the pressure on the inflow side is large, the lift is performed with a relatively small driving force. And the flow rate can be adjusted. Therefore, since components for flow control are unnecessary, the number of components can be reduced, and an inexpensive flow control valve can be provided.
【００２４】また、流量は主弁径に依存されるので主弁

弁も閉成するため流出状態が継続することはない。When current supply is stopped due to a power failure or the like while using the flow control valve, the control valve body contacts the valve seat by the biasing force of the spring and is automatically closed by closing. Since the main valve is also closed, the outflow state does not continue.
【００３３】したがって、フェイルセーフが確保された
