    • A pressure shut-off valve unit for a pressure accumulator vessel. A valve housing has a valve chamber with an accumulator region, an intake opening and an outlet opening facing the pressure accumulator vessel. A piston has at least one axial connecting channel, a first effective piston surface facing an inlet region of the valve chamber and a second effective piston surface adjacent to the accumulator region, the piston being axially movable via a change in pressure of the accumulator region of the valve chamber. Sealing elements are arranged in the valve chamber and which are configured to guide in an axially movable manner the piston. A sealing body of the at least two sealing elements or the valve housing form a valve seat, and a passage opening arranged between the intake opening and the outlet opening is reversibly closed and opened via a change in pressure of the accumulator region of the valve chamber. In a unpressurized state, the passage opening is kept open by at least one spring. The accumulator region of the valve chamber is configured for connection to the inlet region of the valve chamber.
    • 用于蓄压器容器的压力截止阀单元。 阀壳体具有带有蓄压器区域的阀室,进气开口和面向蓄压器容器的出口。 活塞具有至少一个轴向连接通道,面对阀室的入口区域的第一有效活塞表面和与蓄能器区域相邻的第二有效活塞表面,活塞可经由储罐区域的蓄压器区域的压力变化而轴向移动 阀室。 密封元件布置在阀室中,并且构造成以可轴向方式引导活塞。 所述至少两个密封元件或所述阀壳体的密封体形成阀座,并且布置在所述进气开口和所述出口之间的通道开口可逆地闭合并经由所述阀室的储存器区域的压力变化而打开 。 在非加压状态下,通道开口由至少一个弹簧保持打开。 阀室的蓄能器区域构造成连接到阀室的入口区域。

    • A pressure reducer having a high pressure inlet, a low-pressure outlet and a valve having a valve seat and a cooperating movable piston valve. With displacement of the piston valve away from the valve seat, a path between the high pressure inlet and the low pressure outlet is opened. In addition, a closing force caused by a low pressure acts on the piston valve towards the valve seat during operation of the pressure reducer. A spring is also provided for the purpose of exerting an actuating force on the piston valve to move away from the valve seat in the valve opening direction. A solenoid coil is configured to exercise a magnetic force superimposed on the closing force or the actuation force acting on the valve piston.
    • 具有高压入口,低压出口和具有阀座和配合活动活塞阀的阀的减压器。 由于活塞阀离开阀座的位移,高压入口和低压出口之间的路径被打开。 此外,在减压器的操作期间,由低压引起的关闭力作用在活塞阀朝向阀座。 还提供弹簧,用于在活塞阀上施加致动力以在阀打开方向上远离阀座移动。 螺线管线圈构造成运动叠加在作用在阀活塞上的关闭力或致动力上的磁力。
