A top of rail (TOR) applicator has a bar positioned in a housing and an exit orifice on the upper portion of the bar for delivering a friction control composition to the crown of a railhead. The upperportion of the bar slopes away from the friction control composition exit orifices. The bar may be composed of an elastomer such as polyurethane. Passageway extend from an inlet or entry orifice to the exit orifices. The friction reduction composition is pumped into the entry orifice, through the passageways to the exit orifices and then onto the crown of the railhead. The friction reduction composition may be thixotropic.
一种轨顶(TOR)涂敷器具有:杆,其定位在壳体中;以及退出孔口,其在杆的上部部分上以用于将摩擦控制组合物递送到轨头的冠部。杆的上部部分倾斜远离摩擦控制组合物退出孔口。杆可由诸如聚氨酯之类的弹性体构成。通路从入口或进入孔口延伸到退出孔口。摩擦减少组合物被抽送到进入孔口中,穿过通路到退出孔口,并且然后到轨头的冠部上。所述摩擦减少组合物可为触变的。
