The seat valve is located in the valve chamber 47, where the pressure medium passages 65 and 74 pass through the end faces 59 and 67 of both magnet actuators 33. As shown in FIG. When the valve 14 is opened from the closed position, additionally, a force acting in the closing direction is generated on the magnet mover 33, which is located in the partially closed position in which the seat valve is displaced from the stop position. . The magnet actuator 33 and the valve tappet 34 constitute separate components, which are coupled to each other in one sealing seat 61. The valve tappet 34 is formed as a plastic injection molding, and has a valve part chamber 51 and a vertical hole as part of the pressure medium passage 65 connected thereto.

밸브(14)는 특히 자동차의 미끄럼 제어된 액압 브레이크장치에서 사용된다.The valve 14 is used in particular in sliding controlled hydraulic brakes in motor vehicles.
