    • A structure of an idle speed control actuator for an engine is provided to mount a path opening/closing element in a choke preventing path for preventing malfunction of the engine without any additional electric element even when a negative pressure amplification path is choked by impurities. A structure of an idle speed control actuator for an engine includes an air passing unit(30) mounted at a side of a suction hole of the idle speed control actuator(14) for passing air via the suction hole even when the suction hole is choked by impurities. The air passing unit has a block member(33) forming a negative pressure amplification path(31) in the suction hole and a choke preventing path(32) at the upper side for passing air even when the negative pressure amplification path is choked, and a path opening/closing device(40) mounted in the choke preventing path for opening the same when the negative pressure amplification path is choked by the impurities. The path opening/closing unit has a mounting path wider than the choke preventing path, a valve mounted in the mounting path and operating by pressure difference of the suction hole to open the mounting path, and a spring mounted in the mounting path in front of the valve to be pressed by the valve.
    • 提供用于发动机的怠速控制致动器的结构,即使当负压放大路径被杂质阻塞时,也可以将路径打开/关闭元件安装在扼流圈防止路径中,以防止发动机的故障,而没有任何额外的电气元件。 用于发动机的怠速控制致动器的结构包括安装在怠速控制致动器(14)的吸入孔侧的空气通过单元(30),用于通过吸入孔使空气通过,即使当吸入孔堵塞时 通过杂质。 空气通过单元具有在吸入孔中形成负压放大路径(31)的阻挡构件(33),以及即使在负压放大路径被阻塞时也在上侧通过空气的阻流路径(32),以及 当所述负压放大路径被所述杂质阻塞时,安装在所述扼流圈防止路径中以将其打开的路径打开/关闭装置(40)。 路径打开/关闭单元具有比防扼流路更宽的安装路径,安装在安装路径中并通过吸孔的压差操作以打开安装路径的阀,以及安装在安装路径前面的弹簧 阀被阀门按压。
