摘要： The object of the invention is an effective automatic adjustment to reduce the sectional area of flow following a closure of the valve. The valve (10) has a magnetic armature (21) which moves longitudinally in a valve dome (14) and has divided valve tappet (22) that bears a closing member (24) of a first seat valve (30) which is open in its rest position. The first seat valve (30) is situated in a valve chamber (35) from which a first pressure-medium channel (45) leads to a control chamber (46) of the magnetic armature (21) away from the closing member (24) and a second pressure-medium channel (48) leads to a control chamber (49) near the closing member (24). Provided also is a second valve (51) formed by the magnetic armature (21) and the valve tappet (22) and used to open and close the connection between the first pressure-medium channel (45) and the second control chamber (49). When the second valve (51) assumes its open position the pressure in the control chamber (46) away from the closing member (24) causes a displacement of the magnetic armature (21) counter to the force of a recoil spring (31), resulting in a reduction of the sectional area of flow of the first seat valve (30). The valve (10) can be used especially in hydraulic antiskid braking systems in motor vehicles.

摘要： The object of the invention is an effective automatic adjustment to reduce the sectional area of flow following a closure of the valve. The valve (10) has a magnet armature (21) which moves longitudinally in a valve dome (14) and whose tappet (22) bears a closing member (24) of a first seat valve (30) which is open in its rest position. The first seat valve (30) is situated in a valve chamber (35) from which two pressure-medium channels (45 and 48) lead to chambers (46 and 49) provided axially at either end of the magneto armature (21). The connection between the control chamber (46) away from the closing member (24) and the balance chamber (49) near the closing member (24) can be opened and closed by the magnet armature (21) using a second seat valve (51) which is open in its rest position. When the second seat valve (51) assumes its closed position the pressure in the control chamber (46) away from the closing member (24) causes a displacement of the magnet armature (21) counter to the force of a recoil spring (31), resulting in a reduction of the sectional area of flow of the first seat valve (30). The valve (10) can be used especially in hydraulic anti-lock braking systems in motor vehicles.

摘要： The object of the invention is an effective automatic adjustment to reduce the sectional area of flow following a closure of the valve. The valve (10) has a magnetic armature (21) which moves longitudinally in a valve dome (14) and whose tappet (22) bears a closing member (24) of a first seat valve (30) which is open in its rest position. The first seat valve (30) is situated in a valve chamber (35) from which two pressure-medium channels (45 and 48) lead to faces (47 and 49) of the circumferentially sealed magnetic armature (21). The connection between the pressure-medium channel (45) and a control chamber (46) between the face (47) of the magnetic armature (21) away from the closing member (24) and the valve dome (14) can be opened and closed by means of a second seat valve (54) which is closed in the rest position. When the second seat valve (54) assumes its open position the pressure in the control chamber (46) away from the closing member (24) causes a displacement of the magnetic armature (21) counter to the force of a recoil spring (31), resulting in a reduction of the sectional area of flow of the first seat valve (30). The valve (10) can be used especially in hydraulic antiskid braking systems in motor vehicles.
