    • Apparatus for controlling the working stoke of the hydraulic props of a mine roof support unit is disclosed. The control apparatus comprises a control valve whose input side is connected to a hydraulic pressure line, and whose output side is connected to a working chamber of each of the props via a respective supply line. A sequence valve is provided in the supply line leading to one of the props. The sequence valve is such as to open the associated supply line when subjected to a predetermined hydraulic pressure, this predetermined hydraulic pressure being at least approximately equal to the hydraulic pressure necessary to overcome the resistance to the working stroke of another of the props. The sequence valve has a tubular valve body, a valve closure element mounted within the valve body, and a valve seat positioned within the valve body. A spring is provided for biassing the valve closure element towards the valve seat. A control piston carries the valve seat, the control piston having a piston face which, when subjected to hydraulic pressure in the biassing direction of the spring, is effective to displace the control piston so as to move the valve seat away from the valve closure element, thereby opening the sequence valve.

    • A valve device takes the form of a multi-part cartridge with a hollow stepped housing containing a stepped rod. A control piston at one end of the rod is opposed by the force of a main spring in a main chamber remote from the control piston. A valve closure member is axially displaceable relative to the rod. The valve closure member is normally held against a valve seating but pressure on the control piston displaces the rod and causes the valve closure member to be lifted from its seating via stop faces. An auxiliary chamber in the housing leads via a connection to some consumer appliance and forms, the downstream side of the valve. A compensating piston on the rod member opposes a face of the valve closure member open to the auxiliary chamber. A further spring in the auxiliary chamber holds the valve closure member on its seating. The valve can open independently of the control piston should the pressure on the upstream side of the valve exceed the consumer pressure. This upstream side usually leads to either the pressure line or a return line as determined for example, by a change-over valve. The valve closure member will respond reliably to increased pressure on the control piston which only has to overcome predetermined spring force independent of hydraulic pressure in the auxiliary chamber.
    • 阀装置采用具有中空阶梯式壳体的多部分筒形的形式,其包含阶梯式杆。 杆的一端处的控制活塞与远离控制活塞的主室中的主弹簧的力相对。 阀关闭构件可相对于杆轴向移动。 阀关闭构件通常保持在阀座上,但是控制活塞上的压力使杆移位,并使阀关闭构件通过止动面从其座上抬起。 壳体中的辅助室通过与一些消费者用具的连接引出,形成阀的下游侧。 杆构件上的补偿活塞与通向辅助室的阀门关闭构件的面相对。 辅助室中的另一弹簧将阀关闭构件保持在其座上。 如果阀门上游侧的压力超过使用者的压力,阀门可独立于控制活塞打开。 该上游侧通常通过例如通过转换阀确定的压力线或返回线。 阀关闭构件将可靠地响应于控制活塞上的增加的压力,其仅需要克服与辅助室中的液压无关的预定弹簧力。

    • A valve device has a multi-part housing containing a servo-valve with a stem which is axially displaced to operate the valve and an electromagnet with a rod-like armature which is axially displaced when the electromagnet is energized. A pivotable lever translates the axial movement of the armature to the stem. For adjustment purpose, an adjustment member is in screw-threaded engagement with the lever remote from the stem. The armature is locked for rotation with the adjustment member. A regulator at the opposite end of the armature to the lever and accessible from the exterior serves to enable the armature to be partially rotated for effecting the adjustment.
