    • A jaw arm (12) for an associated compression tool having cam rollers (36) that displace forwardly and rearwardly along an axis to pivot the jaw arm includes a recess (16) and a notch (60). The recess is disposed adjacent a forward end (42) of the jaw arm. The notch is axially spaced rearwardly from the recess. The recess is configured to receive an associated pipe and an associated coupling for compressing at least one of the associated pipe and the associated coupling to mechanically attach the associated pipe to the associated coupling when the jaw arm is pivotally displaced toward at least one of the associated pipe and the associated coupling. The notch is configured to receive an associated cam roller of the associated compression tool (28) and to retain the associated cam roller to inhibit axial rearward movement of the associated cam roller when the associated cam roller has been received in the notch.
    • 用于相关联的压缩工具的颚臂(12)具有一个沿轴线向前和向后移动以枢转颚臂的凸轮滚子(36),其包括一个凹槽(16)和凹口(60)。 凹口设置在颚臂的前端(42)附近。 凹口从凹部向后轴向间隔开。 所述凹部构造成接收相关联的管道和相关联的联接器,用于压缩相关联的管道和相关联的联接件中的至少一个,以在颚臂枢转地朝向相关联的管件 管道和相关的联轴器。 所述凹口被构造为接收相关联的压缩工具(28)的相关联的凸轮辊,并且当相关联的凸轮辊已经被接收在所述凹口中时,保持相关联的凸轮辊以阻止相关联的凸轮辊的轴向向后运动。

    • A soft starter for a single-phase motor is provided, wherein the single-phase motor includes a main winding, a start winding and a run capacitor, the main winding and the start winding are connected in series with each other and the run capacitor is connected across the main winding and the start winding connected in series, the soft starter comprises a reactor connected in series with the main winding, an AC contactor having a coil, the coil being connected in parallel with the start winding, when a rotation speed of the motor reaches a predetermined threshold, the AC contactor acts to bypass the reactor. The soft starter of the present invention is used to reduce the start current in the main winding, to increase the start torque and to shorten the start time during the motor's start. Moreover, the present invention also provides a single-phase motor having such soft starter.
    • 提供了一种用于单相电动机的软起动器,其中单相电动机包括主绕组,起动绕组和行驶电容器,主绕组和起动绕组彼此串联连接,并且运行电容器 连接在主绕组和串联的起动绕组上,软起动器包括与主绕组串联连接的电抗器,具有线圈的交流接触器,线圈与起动绕组并联连接,当转速为 电动机达到预定的阈值,交流接触器起作用以绕过电抗器。 本发明的软启动器用于降低主绕组中的启动电流,以增加启动转矩并缩短电动机启动期间的启动时间。 此外,本发明还提供具有这种软起动器的单相电动机。
