Abstract: The present invention controls the pressure and flow rate of fluid, in order to obtain uniform performance, configure a closed loop magnetic circuit so as to include an electromagnet, a flapper, and a yoke material, and elastically deform the flapper itself by Maxwell attractive force generated between a magnetic pole of the electromagnet and the flapper to make the separation distance between the nozzle and the flapper variable. As opposed to a rigid flapper structure that swingably moves around a supporting point, like a conventional servo valve, the electromagnet, the magnetic pole, the nozzle, the flapper, and the like are arranged such that a change in magnetic gap directly leads to a change in air gap.

Abstract: The flow rate control unit 1 is comprised with each of the flow rate control devices 11 connected to (juxtaposedly mounted on) the manifold 2 by the joint 91 interposed between each of the flow rate control devices 11 and the manifold 2. Each of the flow rate control devices 11 can be attached to or detached from the manifold 2 by manually operating (attaching/detaching) the clip 93 without using a tool. Because there is no need to secure space to insert a tool between the adjacent flow rate control devices 11, the mounting pitch between the adjacent flow rate control devices 11 (joints 91) can be reduced to the minimum, allowing miniaturization of the flow rate control unit 1.
