    • A control valve assembly for use in a pump or injector of fuel injection systems is provided. A pump or injector body has a pumping chamber, and a valve chamber. The valve chamber defines a valve seat and has an axial guiding portion. A plunger is disposed in the pumping chamber. A valve body disposed in the valve chamber controls fuel. The valve body has a valve stem defining a seating surface. The valve body further has a valve guide in sliding engagement with the valve chamber guiding portion. The valve body is axially movable with respect to the valve chamber over a stroke range. The valve guide has an outer engagement surface that slidingly engages the valve chamber guiding portion with a clearance fit of at least about 5 micrometers in one embodiment. In another embodiment, the axial length of the engagement surface is at most about 7 millimeters. The reduced axial length and/or the clearance fit improve initial sealing performance and sealing performance over the life cycle of the product.
    • 提供了一种用于燃料喷射系统的泵或喷射器中的控制阀组件。 泵或喷射器主体具有泵送室和阀室。 阀室限定阀座并具有轴向引导部分。 柱塞被设置在泵送室中。 设置在阀室中的阀体控制燃料。 阀体具有限定座面的阀杆。 阀体还具有与阀室引导部滑动接合的阀引导件。 阀体在行程范围内相对于阀室可轴向移动。 在一个实施例中,阀导向件具有外啮合表面,该外接合表面以至少约5微米的间隙配合滑动地接合阀室引导部分。 在另一个实施例中,接合表面的轴向长度至多约7毫米。 减小的轴向长度和/或间隙配合可提高产品寿命周期内的初始密封性能和密封性能。

    • A mobile crushing station for receiving and comminuting excavated material from earth moving vehicles provides at least one moveable skip connected to a chassis or frame for receiving material from vehicles, such as rear unloading vehicles like dump trucks. The skips are configured to move to dump material fed into the skips into a feed hopper. The feed hopper is positioned to guide material onto a feed conveyor, such as an inclined apron conveyor. The feed conveyor is configured to transport material to a feed orifice of a crushing device, such as a sizer, a crusher, or a crushing circuit. The crushing device is configured to crush material fed into the crushing device. The crushing device also has a discharge orifice that is positioned above a portion of a discharge conveyor. The mobile crushing station is moveable so it may be repositioned closer to an excavation site as excavation activities progress.
    • 用于从地面移动车辆接收和粉碎挖掘的材料的移动破碎站提供至少一个连接到底盘或框架的可移动跳跃件,用于从车辆接收材料,例如后卸载车辆如自卸车。 跳槽被配置为移动以将进料到料斗中的料料倾倒到进料斗中。 进料斗定位成将材料引导到进料输送机上,例如倾斜的皮圈输送机。 进料输送机被配置为将材料输送到破碎装置的进料孔,例如筛分机,破碎机或破碎回路。 破碎装置构造成粉碎送入破碎装置的材料。 破碎装置还具有位于排出输送机的一部分上方的排出孔。 移动破碎站是可移动的,因此随着挖掘活动的进行,可以将其重新定位到更靠近挖掘点的位置。
