摘要： An hydraulically-controlled non-return valve for the hydraulic cylinders of a walking mine-roof support is provided with a cylindrical valve-closing member which is spring-loaded in the closing direction and is guided in a valve case in a valve housing, the valve-closing member being sealed off therein by means of a seal. A space on one face of the valve-closing member is connected to a circulating duct by way of a stepped bore in the valve case, which bore contains a spring-loaded throttle member having through-flow bores of which one has a throttle-like reduced cross-section. During setting of the hydraulic cylinder pressurized fluid flows past the opened valve-closing member through inclined bores and, by way of the circulating duct, to the stroke space of the hydraulic cylinder. During retraction of the hydraulic cylinder, a control piston in the non-return valve is loaded at the same time as an annular space in the hydraulic cylinder. The control piston thus lifts the valve-closing member from a valve seat so that the pressurized fluid flows back in the reverse direction. The said space bounding the valve-closing member is connected to the throttle member in such a manner that the valve-closing member is not caused to oscillate by the pressurized fluid flowing back during retraction of the hydraulic cylinder.
摘要翻译：用于行走式矿顶支撑件的液压缸的液压控制止回阀设置有一个圆柱形的阀关闭构件，其在关闭方向上弹簧加载并且在阀壳体中被引导到阀壳体中，阀关闭件通过密封件密封在其中。阀关闭件的一个表面上的空间通过阀壳中的阶梯孔连接到循环管道，该孔包含弹簧加载的节流件，其具有一个具有节流阀的通流孔减少截面。在液压缸的设定期间，加压流体通过倾斜孔流过打开的阀关闭构件，并且通过循环管道流到液压缸的行程空间。在液压缸回缩期间，止回阀中的控制活塞与液压缸中的环形空间同时加载。因此，控制活塞因此将阀关闭部件从阀座提升，使得加压流体沿相反方向流回。围绕阀关闭构件的所述空间以节流构件连接，使得阀闭合构件不会由于在液压缸回缩期间向后流动的加压流体而振荡。

摘要： A pressure-limiting valve for hydraulic fluids comprises a stepped switching piston which is loaded by a closing spring to oppose high fluid pressure obtaining in an inflow duct of the valve. Radial transverse bores branch from an axially-extending bore in the switching piston. When the setting pressure established by the closing spring is exceeded, the transverse bores in the piston move past an O-ring seal as the piston compresses the spring, and pressure fluid thus flows from the axially-extending bore into a discharge duct of the valve. The stepped switching piston is guided in a pressure chamber by a portion of its cross-section which is greater than that in the zone of the O-ring seal. Adjacent the inflow duct, the axially-extending bore in the piston has a reduced flow cross-section. Further radial bores lead from the axially-extending bore in the piston in the region of the stepped portion of the latter.
摘要翻译：用于液压流体的限压阀包括阶梯式开关活塞，其由闭合弹簧加载以抵抗在阀的流入管道中获得的高流体压力。径向横向孔从开关活塞中的轴向延伸的孔分支。当超过由关闭弹簧建立的设定压力时，当活塞压缩弹簧时，活塞中的横向孔穿过O形圈密封件，并且压力流体因此从轴向延伸的孔流入阀的排放管道。阶梯式切换活塞在压力室中被其横截面的大于O形圈密封区域的部分引导。在流入管道附近，活塞中的轴向延伸的孔具有减小的流动横截面。另外的径向孔从活塞的轴向延伸的孔在后者的阶梯部分的区域中引出。

摘要： A control line connects an annular space in an auxiliary hydraulic cylinder of an hydraulically-movable mine-roof support (the auxiliary cylinder being provided to advance a forward, auxiliary, roof-support canopy in the direction of the working face of a mine) to the displacement space of an hydraulic measuring cylinder which is longitudinally displaceable in a direction parallel to the hydraulic advancing cylinder in order to advance the auxiliary roof-support canopy, which is pivoted to the main roof-support canopy, in synchronism with the advancing cylinder mounted in the base of the mine-roof support and attached to an abutment on the working face side of the support. A control valve is connected to the control line and responds to the control line pressure in such a way that, when the pressure falls, it supplies pressurized fluid into the pressure space of the auxiliary cylinder to extend the piston rod thereof, and shuts off again when the pressure increases. An axial bore in the piston rod of the advancing cylinder preferably serves as the measuring cylinder.
