    • PURPOSE:To enable to change the set pressure of an outlet passage at will by a method wherein the opening area of a working gas passage which leads the gas pressure to a main diaphragm chamber. CONSTITUTION:A switching valve 15 opens a small valve seat 13 and in turn closes a by pass valve 14. Because working gas is led through a passage 17 to the main diaphragm chamber 8, the pressure within the main diaphragm chamber 8 ascends with working gas and exceeds the pressure within the outlet passage 3, resulting for a main diaphragm 9 in generating the force intending to open a main valve 4 against a spring 7. When the force generated at the main diaphragm 9 exceeds the force of the spring 7, the main valve 4 starts to open, allowing to fuel gas to start to flow through a port 5 to the outlet passage 3. Simultaneously the pressure within the outlet passage 3 starts to ascend and feeds-back through a passage 26 to a feedback diaphragm 19.
    • 目的:使能够通过将气体压力导向主隔膜室的工作气体通道的开口面积随意改变出口通道的设定压力。 构成:切换阀15打开小阀座13,并通过通阀14关闭。由于工作气体通过通道17被引导到主隔膜室8,主隔膜室8内的压力随工作气体上升 并且超过出口通道3内的压力,导致主隔膜9产生打开主阀4抵抗弹簧7的力。当在主隔膜9处产生的力超过弹簧7的力时, 主阀4开始打开,允许燃料气体开始通过端口5流到出口通道3.同时,出口通道3内的压力开始上升并通过通道26反馈回到反馈隔膜19。

    • PURPOSE:To perform good controlling operation by controlling the variation in the pressure of a controlling pressure chamber by using a system in which a proper throttle means is provided in a pathway for a fluid to be sent under pressure by an electromagnetic pump and led to a controlling chamber. CONSTITUTION:An actuator is provided with an electromagnetic pump 2 by which a fluid inside the first chamber 7 is sent under pressure to the second chamber 8a, a pathway with an orifice 9 through which the fluid of the second chamber 8a is flowed into a pressure chamber 8b while giving it a given resistance, communication paths 10a and 10b with a needle 11 through which the fluid in the pressure chamber 8b is returned to the first chamber 7 while giving it a given resistance, and follower 12 and 13 displacing itself in response to the pressure of the pressure chamber 8b. A fluid sent under pressure by the electromagnetic pump 2 flows into the second chamber 8a and then into the pressure chamber 8b through the orifice 9. Thus, a pulsative movement given to the fluid is smoothened and also the change of pressure in the pressure chamber 8b is suppressed.
    • 目的:通过使用在电磁泵的压力下输送流体的路径中设置适当的节流装置的系统来控制控制压力室的压力变化来进行良好的控制操作,并导致 控制室。 构成:致动器设置有电磁泵2,通过该电磁泵将第一腔室7内的流体在压力下被输送到第二腔室8a,具有孔口9的通路,第二腔室8a的流体通过该孔口流入压力 在给定电阻的同时给予电阻的通气路径10a和10b,压力室8b中的流体通过该针11返回到第一腔室7,同时给定给定的电阻,并且随动件12和13响应于自身移位 压力室8b的压力。 由电磁泵2在压力下发送的流体流入第二室8a,然后通过孔口9进入压力室8b。因此,给予流体的脉动运动平滑,并且压力室8b中的压力变化 被压制

    • PURPOSE:To maintain the stabilized flow rate of fuel gas all the time by controlling the position of a valve body according to the difference between a set value given to a servo valve and the pressure of fluid to be controlled in a control valve for fuel gases. CONSTITUTION:When a certain drive signal is supplied to the coil 23 of an electromagnetic pump 22, a fluid inside a chamber 24 is sent under pressure to a chamber 25 and then returned through a servo valve 3 to the chamber 24. When a desired set signal is given to a coil 31, a plunger 32 moves downwards against a spring 39 to lessen the opening area of a port 36, whereby the pressure inside the chamber 25 is raised and the valve body 14 goes down through a folower 27 and a rod 26. As a result, a fluid inside an inlet pathway 11 flows into an outlet pathway 12 and the pressure inside the pathway 12 is transmitted from a port 16 to a feedback chamber 35. The pressure lifts the plunger 32 through a diaphragm 33 to enlarge the opening area of the pathway 36.
