    • The invention concerns a valve arrangement (1) with a housing (2), an inlet connection (3) and an outlet connection (4), which are connected with each other via a flow path, in which is located a closing device (5), which has a valve seat (7) and a valve element (6) interacting with the valve seat (7), the valve element (6) being loaded in the direction of the valve seat (7) by a resetting device (8) and being acted upon on the side facing the valve seat (7) by a pressure in a first pressure chamber (9), said pressure corresponding to the pressure in the inlet connection (3), when the closing device (5) is closed, and on the side facing away from the valve seat (7) by the pressure in a second pressure chamber (11), which is connected with the outlet connection (4) via a channel arrangement (14), in which is located at least one auxiliary valve (15), and with the first pressure chamber (9) via a throttle (13). It is endeavoured to reliably ensure that the closing device (5) opens. For this purpose, it is provided that the channel arrangement (14) ends in a suction nozzle arrangement (18), which is located in the flow path.
    • 本发明涉及一种具有壳体(2),入口连接件(3)和出口连接件(4)的阀门装置(1),它们通过流动路径相互连接,其中位于关闭装置(5) ),其具有与阀座(7)相互作用的阀座(7)和阀元件(6),阀元件(6)通过复位装置(8)被装载在阀座(7)的方向上 ),并且当所述关闭装置(5)关闭时,通过第一压力室(9)中的压力在所述面对所述阀座(7)的一侧上作用所述压力,所述压力对应于所述入口连接件(3)中的压力 ,并且在通过经由通道装置(14)与出口连接件(4)连接的第二压力室(11)中的压力下在背离阀座(7)的一侧上,其中至少位于 一个辅助阀(15),以及通过节流阀(13)与第一压力室(9)连接。 努力可靠地确保关闭装置(5)打开。 为此,提供了通道装置(14)终止于位于流动路径中的吸嘴装置(18)。
