    • Disclosed is a hybrid actuator comprising a housing having a working oil filling the inside thereof, and an inlet and an outlet communicating with the inner space thereof and controlling the flow rate to allow the working oil to flow into and out of the housing; a piston arranged inside the housing, partitioning the inner space of the housing into a first working chamber and a second working chamber, moving toward the first working chamber or the second working chamber, and having a flow rate control valve which is formed at the middle part thereof and controls the flow rate of the working oil passing between the first and the second working chamber when the piston moves; a hydraulic driving source connected to the inlet and the outlet, and providing a driving force for moving the piston by supplying the working oil into the housing; and an electric driving source connected to the piston, and providing an electric driving force for moving the piston.
    • 公开了一种混合式致动器,其包括具有填充在其内部的工作油的壳体以及与其内部空间连通的入口和出口,并且控制流量以允许工作油流入和流出壳体; 活塞,其设置在所述壳体内部,将所述壳体的内部空间分隔成第一工作室和第二工作室,所述第一工作室和第二工作室朝向所述第一工作室或所述第二工作室移动,并且具有流量控制阀,所述流量控制阀形成在所述中间 的一部分,并且当活塞移动时控制在第一和第二工作室之间通过的工作油的流量; 连接到入口和出口的液压驱动源,并且通过将工作油供应到壳体中来提供用于移动活塞的驱动力; 以及连接到所述活塞的电驱动源,并提供用于移动所述活塞的电驱动力。

    • 본발명은유압또는공압실린더형액추에이터에서로드를통한누설을방지하기위한것으로기존의실링부재와이를구현하기위한로드의표면조도에상관없이특히, 케이블(와이어)을로드로사용할수 있는액추에이터를제공하는것을기술적과제로한다. 본발명은전술한과제를달성하기위해, 본내부에유체가충진되며전방단부를폐쇄하는전방커버가형성된실린더와, 상기실린더내부에서상기유체의의해변위되는피스톤과, 상기피스톤에일 단부가고정되고타 단부가상기전방커버에고정되는중공형실링부재와, 상기실링부재의내부에삽입되어상기피스톤에일 단부가고정되고타 단부가상기전방커버의외부로연장되는작동부재를포함하여이루어지는것을특징으로한다. 본발명에서는전술한구성으로인해유체(f)의실링은이미실링부재에의해확보되는바, 작동부재는실링부재의내부에서실링부재에슬립되기만하면이동되는작용을하게된다. 따라서, 로드또는케이블이실링부재에긴밀하게밀착된상태로이동할필요가없게되므로종래기술에서와같이케이블이실링부재와긴밀하게밀착된상태에서이동하는경우에비해실링부재마모측면에서대폭적으로개선되며, 로드를매끄럽고정밀하게가공하거나케이블을매끄럽고단단하게코팅하는것이필요하지않는장점을가지게된다.
