摘要： In an emergency hydraulic control, in which in an open hydraulic circuit for supplying the various piston chambers of the secondary and primary axial adjusters, at least one throttle valve is disposed. For regulating the primary and secondary pressure, a primary and secondary valve are used, respectively. Each valve is triggered in turn via a respective electromagnetically actuated pilot control valve in the pilot control valve that opens in emergency operation; the pilot control valves are connected to the outlet of the secondary valve, among others, via orifice valves. The pressure fluid pressure in the primary piston chamber is additionally limited by a pressure limiting valve. The outlet of this pressure limiting valve is connected via a control line to the control line located between the primary pilot control valve and the primary valve. At the same time, an orifice valve is disposed between the discharge point of the control line, disposed at the outlet of the pressure limiting valve, into the control line arriving from the pilot control valve and the branching point of this control line from the lead line to the primary-side pilot control valve. The emergency hydraulic control makes a constant clamping force ratio possible, even at low pump feed quantities or low engine speeds. As a result, on startup of the vehicle, a gear ratio adjustment to “overdrive” is avoided, and the next time the engine is started a gear ratio adjustment in the direction of “low” is possible.
摘要翻译：在紧急液压控制中，在用于供应次级和主轴向调节器的各个活塞室的开放液压回路中设置有至少一个节流阀。为了调节初级和次级压力，分别使用主阀和次阀。每个阀门依次通过在紧急操作中打开的先导控制阀中的相应的电磁致动先导控制阀来触发; 先导控制阀通过孔阀连接到二次阀的出口。主活塞室中的压力流体压力另外受限压阀的限制。该限压阀的出口通过控制线连接到位于主控制阀和主阀之间的控制线。同时，在控制线的排出点之间设置孔口阀，该控制管路的排出点设置在限压阀的出口处，从控制管路到达的控制线和该控制线的分支点从引线直线到初级侧先导控制阀。即使在低泵送量或低发动机转速下，紧急液压控制也可以保持恒定的夹紧力比。结果，在车辆起动时，避免了“过驱动”的变速比调整，并且下一次发动机起动时，可以进行“低”方向的变速比调整。

摘要： A pressure control valve includes a housing, a valve slide guided in the housing, on which at least one inflow control edge is configured, which cooperates with an inflow opening in the housing, a constriction in piston being present adjacent to inflow control edge, which lies at least approximately opposite to a control opening. It is provided that the valve slide have a circumferential annular groove, which lies on the side of the inflow control edge facing away from the constriction and approximately opposite the inflow opening.
