Abstract:
An electromagnetic hydraulic valve (1) is provided having a magnetic armature (8) which is guided in a longitudinally movable fashion in an armature guide (9) and activates a valve push rod (15) which extends in a valve housing (14). The valve push rod (15) controls the connection between connection openings (28, 29, 30), formed in the valve housing (14), for hydraulic medium in that the valve push rod (15) is operatively connected to one or more sealing bodies (22, 23) which correspond to one or more sealing sleeves (17, 18) supported in the valve housing (14). The hydraulic valve (1) includes an arrangement for precipitating particles of dirt, which element includes an intermediate floor (31), which is arranged between the armature guide (9) and the connection openings (28, 29, 30). The intermediate floor (31) forms a hydraulic seal with an inner casing surface (16) of the valve housing (14), and the valve housing (14) is formed of a magnetizable material in order to precipitate ferromagnetic particles of dirt.
