    • The invention relates to a hydraulic directional valve (1) having an electromagnetic actuating unit (2) and a valve section (3), an essentially cylindrical, blind-hole-like receptacle (19b) being formed on one component of the actuating unit (2), a flange section (27a) of a valve housing (27) of the valve section (3) engaging in the receptacle (19b), the flange section (27a) being provided with an annular groove (27b) which runs in its circumferential direction, and an essentially hollow-cylindrical wall (19a) of the receptacle (19b) in the region of the annular groove (27b) engaging in said annular groove (27b) in such a way that it bears on the groove base (27c) of said annular groove (27b), along the entire circumference of said annular groove (27b). Means are proposed for increasing the torsional rigidity between the flange section (27a) and the wall (19a). In this context, particular emphasis is placed on processing reliability and economic viability of the connecting process.
    • 本发明涉及具有电磁致动单元(2)和阀部分(3)的液压方向阀(1),基本上圆柱形的盲孔状容器(19b)形成在致动单元的一个部件上( 2),阀部分(3)的阀壳体(27)的凸缘部分(27a)接合在容器(19b)中,凸缘部分(27a)设置有环形槽(27b) 圆周方向,以及在所述环形槽(27b)的与所述环形槽(27b)接合的区域中的所述容器(19b)的基本上中空的圆柱形壁(19a),使得其承载在所述槽基部 )沿所述环形槽(27b)的整个圆周。 提出了用于增加凸缘部分(27a)和壁(19a)之间的扭转刚度的方法。 在这方面,特别强调处理连接过程的可靠性和经济可行性。
