Abstract

A hydraulic directional valve having an electromagnetic actuating unit and a valve section, an essentially cylindrical, blind hole-like receptacle being formed on one component of the actuating unit, a flange section of a valve housing of the valve section engaging in the receptacle, the flange section being provided with an angular groove which extends in a circumferential direction, and an essentially hollow cylindrical wall of the receptacle in the region of the annular groove engaging in said annular groove in such a way that it bears on the groove base of the annular groove, along the entire circumference of said annular groove. The torsional rigidity between the flange section and the wall is increased. In this context, particular emphasis is placed on processing reliability and economic viability of the connecting process.
