本发明与利用流体压力而工作的机构有关,主要是讨论一个旋转伺服阀控制机构,其中伺服阀随导弹或类似的自动驾驶仪发出的指令而动作。现在可用的是翼面的定位机构。在这种机构中,两个马达室设有与确定翼面位置的装置有联系的活塞,而马达室通过各自的节流孔与流体压力源相通。并且设有依指令信号确定活门位置的输出节流孔。活门位置的改变将改变马达室中作用于活塞有效面积上的压力,以达到按指令信号确定翼面位置的目的。
The present invention relates to a mechanism that operates with fluid pressure and mainly discusses a rotary servo valve control mechanism in which the servo valve operates with instructions issued by a missile or similar autopilot. Available now is the airfoil positioning mechanism. In such a mechanism, the two motor chambers are provided with pistons associated with the means for determining the position of the airfoil, and the motor chambers are in fluid communication with the source of fluid pressure through their respective orifices. And there is an output orifice that determines the position of the shutter in response to a command signal. Changes in the position of the valve will change the pressure in the motor chamber acting on the effective area of the piston in order to achieve the purpose of determining the position of the airfoil as instructed by the command signal.
