摘要： An electromagnetically actuated valve which achieves the setting of a reduced cross section of flow following a closed position of the valve. The solenoid valve has a seat valve which is surrounded by a sleeve which is secured pressure-tightly on a valve body. In the closed position of the seat valve, a tappet engages in the sleeve, forming a small radial gap. From the interior of the sleeve, a first pressure-medium passage leads to an end face of a magnet armature, said end face being remote from the seat valve. Outside the sleeve, a second pressure-medium passage leads to that end face of the magnet armature which is close to the seat valve. In the case of a pressure drop between the pressure-medium inlet and the pressure-medium outlet of the solenoid valve, the seat valve can assume a partially open position following a closed position of said valve since, due to the gap, which acts as a restriction, a pressure disequilibrium arises at the magnet armature and valve opening forces are compensated. The valve can be employed in slip-controlled hydraulic brake systems of motor vehicles.

摘要： [The aim is to] A solenoid valve which achieves a setting of a reduced flow area which is active after a closed position of the valve is disclosed. The solenoid valve has a seat valve in a valve chamber. A magnet armature for actuating the seat valve is provided on its end face remote from the seat valve with an axially expandable hollow part whose interior, acting as a control chamber, is connected to a valve sub chamber through a pressure fluid channel. A [D]dynamic pressure is generated in the partly open position of the seat valve in the valve subchamber and is capable through expansion of the hollow part in the control chamber of causing a force which acts on the magnet armature against the force of a resetting spring and on the basis of which the seat valve maintains its partly open position. The valve can be used in slip-controlled hydraulic brake systems of motor vehicles.

摘要： A magnet valve with low noise upon shutoff from the pressure limiting function. The magnet valve has a two-part valve tappet, whose inner valve tappet part has the closing member of a seat valve. The closing member is circumferentially engaged in spaced-apart fashion, forming a gap space, by a tubular portion of the outer valve tappet part. From the gap space, a pressure fluid conduit leads to a control chamber, which is located between the face end, remote from the seat valve, of a magnet armature that cooperates with the valve tappet, and a valve dome. Upon shutoff of the magnet valve, the seat valve changes from its closing position to a partly open position, in which dynamic pressure in the gap space becomes operative and is transmitted through the pressure fluid conduit into the control chamber. The hydraulic force that is operative there on the magnet armature acts counter to the opening forces of the magnet valve and slows down its opening motion. Because of the thus-throttled flow of pressure fluid through the seat valve, a pressure surge is averted. The magnet valve can be used in slip-controlled motor vehicle brake systems.

摘要： An electromagnetically operated valve which attains an automatic establishment of a reduced flow cross section that is effective after a closing position of the valve. The valve has a magnet armature, longitudinally movable in a valve dome, with a valve tappet for actuation of a seat valve. The seat valve is located in a valve chamber from which pressure fluid conduits, leads to upper and lower face ends of the circumferentially sealed off magnet armature. When the valve is opening from the closing position, an additional force acting in the closing direction upon the magnet armature is generated because of the shaping of the seat valve, and as a result of this additional force the seat valve assumes a partly closed position that is different from its position of repose. The valve is applicable particularly to traction-controlled hydraulic brake systems of motor vehicles.

摘要： A solenoid valve having a first seat valve for performing a closing function and a second seat valve, connected in parallel thereto, for a pressure-limiting function. A pressure medium spilled by the second seat valve flows off through a flow-off bore acting as a throttle. Pressure surges are thus largely avoided in the part of the brake system located on the flow-off side. The solenoid valve can be used in controlled-slip hydraulic brake system of motor vehicles.

The shaped part is received tightly on the opening end of a bore of a housing and surrounds an extension of a support body disposed in the bore. Provided on a side face of the extension is a groove, which communicates with a chamber in the extension. The shaped part, which on its outside is exposed to the brake fluid, with the inside of its jacket wall defines a hollow chamber, formed toward the extension of the support body and having atmospheric pressure. The vibration damper can be used in a slip-controlled hydraulic brake systems of motor vehicles.

摘要： The valve has a seat valve with a hollow cone-shaped valve seat (28) and a closing member in the form of a segment of a ball. The valve seat is centrally fed by an influx bore that communicates with a pressure fluid inlet. A tappet that has the closing member is engaged by a magnet armature that acts on the seat valve in the closing direction and by a restoring spring that acts on it in the opening direction. The valve, which is embodied as an on-off valve, can be controlled in stable intermediary positions because of the following measures: the sealing diameter of the valve seat has at least 1.3 times the diameter of the influx bore; the cone angle of the valve seat is at most 110.degree.; the magnetic force can be smoothly changed, wherein its course decreases monotonously with an increasing valve opening stroke; the force on the closing member, produced by the pressure fluid and the restoring spring, has a monotonously decreasing course with increasing valve opening stroke, whose inclination is quantitatively greater than that of the magnetic force progression.

摘要： This invention achieves a setting of a reduced flow area which is active after a closed position of the valve. The solenoid valve has a seat valve with a closing element which is surrounded with a clearance by a hollow cylindrical shoulder. Formed in a valve body provided with the valve seat of the seat valve is an annular channel into which the shoulder engages with a slight radial gap in the closed position of the valve. On the outlet side of the seat valve, the pressure fluid channel leads to the two end faces of a magnet armature which actuates the seat valve. Given a pressure gradient between the pressure fluid inlet and the pressure fluid outlet, after a closed position of the solenoid valve the seat valve is capable of assuming a partly open position, since valve opening forces are compensated by pressure disequilibrium at the magnet armature. The valve can be used in slip-controlled hydraulic brake systems of motor vehicles.
