摘要： A 3-port, 2-position, directional control valve has two cylindrical closure elements for the alternate connection of a control line to a return flow line and a high pressure line. The switching force exerted on a thrust member is transmitted via pressure pins, and a manifold member with a centrally-positioned axial bore connected to the control line is arranged between the closure elements. Sealing elements on the closure elements seal the exit openings of the bore in the manifold member alternately. One of the pressure pins extends through the manifold member eccentrically while extending parallel to the axial bore and is always under pressure, like the high-pressure-side closure element, so that the closure element on the low pressure side is always held open in the zero position of the valve while the closure element on the high pressure side is acted on by the pressure medium in the direction of closure. The switching force required to open the valve is small because the pressurized cross-sections of the axial bore and the pressure pin are constructed to be small.
摘要翻译： 3端口，2位置的方向控制阀具有两个圆柱形闭合元件，用于将控制线交替连接到回流管线和高压管线。施加在推力构件上的切换力通过压力销传递，并且具有连接到控制线的中心定位的轴向孔的歧管构件布置在闭合元件之间。闭合元件上的密封元件交替地密封歧管构件中的孔的出口。其中一个压力销偏心地延伸穿过歧管构件，同时平行于轴向孔延伸，并且一直处于压力下，如高压侧闭合元件，使得低压侧的闭合元件总是在阀的零位置，而高压侧的封闭元件由压力介质沿关闭方向作用。打开阀门所需的开关力很小，因为轴向孔和压力销的加压横截面被构造得很小。

摘要： A method of electro-hydraulic control of the cutting and self-advancing mine-roof support units in an automated longwall is carried out in dependence on the measured lengths to which the rams pushing the support are extended, with extraction by the cutter occurring in long cuts extending over almost the entire length of the longwall. After each extraction cut, the conveyor is advanced by an amount equal to the depth to which the cutter has cut, and the process of advancing each group is triggered in dependence on the length to which the pushing rams have been extended. The self-advancing roof-support units inserted in the longwall are divided into groups which, depending on the respective state of operation, are moved forward individually and successively, in each case by a preset extension length of the pushing rams.

摘要： A self-advancing mine roof support has a beam-like abutment adapted to be disposed generally adjacent and parallel to a work face. Three roof support elements are spaced apart along the abutment and are pivoted to the abutment. The abutment may be angled relative to the direction of advance by arranging the three support elements in staggered formation. A beam of the central support element is pivoted to the abutment. The two outer roof support elements are connected to the abutment by a linkage, e.g., guide arms, which allows the abutment to pivot about the beam of the central element without changing the distance between the three elements as measured at right angles to the direction of advance.
