    • An electromagnetic valve comprises a magnetic circuit formed by a stationary core and a movable core, or armature pivoted at one end of the stationary core and rotatable continuously between first and second positions with a free end positioned in opposed relation to the other end of the stationary core with an air gap therebetween. The armature is spring biased so as to remain in the first position and carries a valve head for engagement with a valve seat. The opposing ends of the stationary and movable cores are so shaped as to form in the air gap a first working section in which the main magnetic flux generates a vector component transverse to the length of the armature and a second working section in which the main magnetic flux generates a vector component parallel to the length of the armature. The resulting vector makes the angular displacement of the armature linearly proportional to the supply current.
    • 电磁阀包括由固定铁芯和可动铁芯形成的磁路,或者在固定铁芯的一端枢转并且可在第一和第二位置之间连续旋转的电枢,其自由端位于与固定铁芯的另一端相对的位置 芯之间具有气隙。 电枢被弹簧偏压以便保持在第一位置并且承载用于与阀座接合的阀头。 固定和可动铁芯的相对端被成形为在气隙中形成第一工作部分,其中主磁通量产生横向于电枢长度的矢量分量;以及第二工作部分,其中主磁 磁通产生平行于电枢长度的矢量分量。 所得矢量使电枢的角位移与电源电流成线性比例。

    • An instantaneous water heater with enhanced temperature control and less variation in output water temperature has an output hot water pipe extending into a heating tank through the top thereof and surrounded by a coiled sheath electric heater for heating the water in the tank, the output pipe extending to the tank bottom and provided with an inlet thereat. An inlet pipe for water to be heated extends into the bottom of the tank and is throttled to provide an accelerated flow of incoming water away from the heater and outlet pipe toward an overheat prevention thermostat mounted externally on the top of the tank and connected to the heater. An output hot water temperature sensor located within the output water pipe adjacent the inlet thereof cooperates with a control unit of regulating operation of the heater to maintain the hot water output temperature at a preset level. The inlet to the water output pipe is throttled to insure mixing of the heated water, accurate temperature measurement and the reduction of scale deposition on the temperature sensor.
    • 具有增强温度控制和输出水温变化小的瞬时热水器具有输出热水管,其通过其顶部延伸到加热罐中,并被卷绕的护套电加热器包围,用于加热罐中的水,输出管延伸 到罐底,并在那里设有一个入口。 用于待加热的水的入口管延伸到罐的底部并被节流,以将进入的水的加速流从加热器和出口管朝向安装在罐的顶部外部并连接到罐的过热预防恒温器 加热器。 位于输出水管附近的输出热水温度传感器与加热器的调节操作的控制单元配合,以将热水输出温度保持在预设水平。 水输出管的入口被节流以确保加热的水的混合,精确的温度测量和减少温度传感器上的垢沉积。
