Embodiment Construction

[0015] exist figure 1 10 is usually used to represent the hydraulic vehicle braking system. The illustrated embodiment of the vehicle braking system 10 includes valves and other components described below to provide electronic brake control capability. The vehicle braking system 10 is intended to be exemplary, and it should be understood that there are other brake control system configurations that may be used to implement the various valve embodiments described herein. In other embodiments, braking system 10 may include components for providing anti-lock braking, traction control, and / or vehicle stability control functions.

[0016] The vehicle brake system 10 has two separate brake circuits 11A and 11B respectively, in figure 1 The two brake circuits are shown on the left and right halves of . exist figure 1 In the exemplary embodiment shown, the circuit supplies brake pressure to the front and rear wheel brakes. The shown rear wheel brakes are arranged diagonally with ...

Abstract

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).
