Patent DE-4432046-A1 (DE)
Title: Electromagnetic valve esp. for skid control hydraulic brake system in vehicles
Inventor: OEHLER MARTIN DIPL ING
IPC: B60T8/50
Filed: 1994-09-09
Abstract: A magnetic armature (33) is arranged for longitudinal movement to be received in the valve dome (26). The latter is surrounded by a magnetic coil (29). A valve plunger (34) with a closure member (36) of a first seat valve (43) is associated with the armature (33). A valve body (39) with a valve seat (41) is arranged in the valve housing (23). The valve body (39) had a central bore (40) as a pressure medium inlet of the first seat valve (43). When the coil (29) is not excited, the closure member (36) is lifted by the force of a return spring (44) from the valve seat (41). The first seat valve (43) is in a valve chamber (48) in connection with the pressure medium outlet. The chamber has a retaining capacity partial chamber (64). A first channel (65) passing through the plunger and armature goes from this chamber (64) to a control chamber (66). A second channel (68) goes from the valve chamber (48) to the closure side of the armature (33). Pressure generated in the partial chamber (64) causes in the control chamber (66) a force acting on the armature against the return force of the spring (44). This causes the seat valve to take a partially closed position different from its rest position. The end (67) of the armature furthest from the closure defines the control chamber (67). The other end (69) defines a second control chamber (70) in connection with the second channel (68). A second seat valve (78) blocks the first channel when the first seat valve (43) is in its rest position. The armature forms a movable valve seat (81) of the second seat valve (78) around the mouth of the first channel while the valve dome (26) is formed as the closure member. The first control chamber is sealed from the second with a lesser seal than that of the second seat valve (78) in its closed position.
