摘要： An electromagnetic valve (32) for use in controlling fluid flow between first and second passageways (P1, P2) in a hydraulic valve block (4), includes a valve body (51). The valve body (51) defines a central axis (A), has a central opening (51A) therethrough, has a lower end (54) adapted to be inserted into a bore (19) of the valve block (4), and is provided with a lower cylindrical opening (70). An armature (56) is axially movable within the valve body (51) and is biased by a spring in one axial direction (57A). A closing element (88) is carried by a lower end (54) of the armature (56). An electromagnetic coil (64) coaxially surrounds the armature (56) and is operable to effect axial movement of the armature (56) in an axial direction opposite the one direction (57B). A valve seat member (62) is carried by the lower end (54) of the valve body (51) and has an orifice (98) providing fluid flow between the first and second valve block passageways (P1, P2). The valve seat member (62) defines a valve seat (96) surrounding the orifice (98) and cooperates with the closing element (88) for selectively closing the orifice (98). The valve seat member (62) includes a cylindrical tubular portion (90) frictionally retained in the lower cylindrical opening (70) of the valve body (51). The lower cylindrical opening (70) of the valve body (51) is provided with a stop surface (68) at the upper end of thereof, and an upper part (92) of the cylindrical portion (90) of the valve seat member (62) includes a flange (100) engageable with the stop surface (68) for limiting downward movement of the valve seat member (62) relative to the valve body (51).
