    • A proportional pressure control valve serves as a direct control valve with a pressure reducing function and a pressure holding function. The valve, includes a valve housing (2) with inlet and outlet . ports (4, 5, 6), a control element (7) which has a feedback facility, an armature rod (15) and a proportional magnet (3). The proportional magnet is comprised of a magnet core (17), a magnet armature (16) and a magnet coil (18), wherein this proportional magnet (3) in its operational range possesses a nearly constant magnetic force. In accordance with the invention, in a holding position of the magnet armature (16), the smallest axial space (21) between the magnet armature (16) and the magnet core (17) is so dimensioned, first, that the magnetic force between these two components (16, 17) when in the holding position is greater than the magnetic force in the operational zone of the proportional magnets (3), and second, that the magnet armature (16) can be fixed in the holding position by this magnetic force.
    • 比例压力控制阀用作具有减压功能和压力保持功能的直接控制阀。 阀门包括一个带入口和出口的阀门壳体(2)。 端口(4,5,6),具有反馈设备的控制元件(7),电枢杆(15)和比例磁铁(3)。 比例磁体包括磁芯(17),磁体电枢(16)和磁体线圈(18),其中该比例磁体(3)在其工作范围内具有几乎恒定的磁力。 根据本发明,在磁体电枢(16)的保持位置,磁体电枢(16)与磁芯(17)之间的最小轴向空间(21)的尺寸确定为: 这两个部件(16,17)当处于保持位置时大于比例磁体(3)的操作区域中的磁力,其次,磁体衔铁(16)可以通过该固定位置固定在保持位置 磁力。

    • A pressure control valve device with at least one inlet area and first and second outlet areas which can be connected by two poppet valves. A flow guide device (21), with inflow and outflow areas (22, 23) for guiding the fluid flowing from the inlet area in a defined manner in the direction of the second poppet valve, is located upstream of the second poppet valve, between the first and second outlet areas. The fluid in the flow guide device (21) passes in the area between the inflow and outflow areas (22, 23) through a plurality of channel areas distributed around the periphery of the flow guide device (21) and separated from one another, which are shaped at least approximately helically and impart an at least approximately vortex-like flow pattern to the fluid flowing in the direction of the second poppet valve downstream of the outflow area (23).
    • 一种具有至少一个入口区域和可通过两个提升阀连接的第一和第二出口区域的压力控制阀装置。 具有用于沿着第二提升阀的方向以限定的方式引导从入口区域流动的流体的流入和流出区域(22,23)的流动引导装置(21)位于第二提升阀的上游,位于第二提升阀 第一和第二出口区域。 流动引导装置(21)中的流体通过分布在流动引导装置(21)的周边周围的多个通道区域在流入区域和流出区域(22,23)之间的区域中通过,并且彼此分离, 至少大致螺旋形地形成至少大致涡旋状流动图案,该流动图案流向在流出区域(23)下游的第二提升阀的方向。
