摘要： An normally closed-type fluid control valve, having a guide standing through a counter member on the side of an upper surface of a valve base is provided with a cylindrical member having an engaging portion at its lower end and movable up and down on an inner the side thereof. Cylindrical member is provided with an actuator therewithin so that the actuator may be held by the cylindrical member. A support member 051452225 is fixed in position by means of the counter member and the guide is inserted into a hole opened at a position below a lower end portion of the actuator. A lower end side of the actuator is engaged with an upper surface of the support member and a pressing spring is interposed between the support member and the engaging portion of the cylindrical member to press a valve body against a valve seat formed in the valve base, whereby closing the said valve so that the pressing spring may be compressed by an output of the actuator during the time when the actuator is acting to separate the valve body from the valve seat, whereby opening the valve.
摘要翻译：一个常闭型流体控制阀，其具有一个直立在阀座上表面一侧的相对构件的导向件，该圆柱形构件在其下端具有接合部分，并可在内壁上上下移动其侧面。圆柱形构件在其中设置有致动器，使得致动器可以由圆柱形构件保持。支撑构件051452225通过计数器构件固定就位，并且引导件插入到在致动器的下端部下方的位置处打开的孔中。致动器的下端侧与支撑构件的上表面接合，并且在支撑构件和圆柱形构件的接合部分之间插入有压簧，以将阀体压靠在形成于阀座中的阀座上，由此关闭所述阀，使得在致动器用于将阀体与阀座分离的时间期间，压力弹簧可以被致动器的输出压缩，由此打开阀。

摘要： A control valve in which a surface of a valve seat closer to a valve body is formed so as to be flat. A valve head corresponding to an annularly formed fluid-communication passage is provided with an annular inner convex projection and an annular outer convex projection. These projections engage with the flat surface of the valve seat on the inner side and the outer side of the fluid-communicating passage, respectively. The valve head is provided with a communicating passage for providing communication between a valve body-driving portion side thereof and a valve seat surface side containing the inner convex projection.
摘要翻译：一种控制阀，其中阀座的靠近阀体的表面形成为平坦的。对应于环形流体连通通道的阀头设置有环形内凸起凸起和环形外凸起凸起。这些突起分别与流体连通通道的内侧和外侧上的阀座的平坦表面接合。阀头设置有用于在其阀体驱动部分侧和包含内凸起凸起的阀座表面侧之间提供连通的连通通道。

摘要： A control valve, in which a valve body opening and closing a valve mouth is driven by a strain force of a piezostack, characterized in that an upper fixed portion of said piezostack is supported by a ring-like tapered surface or a spherical surface and a lower movable portion of the piezostack is combined with a valve body through a spherical bearing.The strain output can be surely transmitted to said valve body by holding the piezostack so that no movement other than a strain resulting from the application of voltage may be produced.
摘要翻译：一种控制阀，其中开启和关闭阀口的阀体由压电堆的应变力驱动，其特征在于，所述压电堆的上部固定部分由环形锥形表面或球形表面支撑，压电堆的下部可移动部分通过球面轴承与阀体组合。通过保持压电堆可以确保应变输出传递到所述阀体，使得不会产生除施加电压的应变以外的运动。
