摘要： A valve having a magnetic armature, which is moved longitudinally in a valve dome; a valve tappet of this armature carries a closing member of a seat valve, which is open when in the rest position. The seat valve is disposed in a valve chamber, from which two pressure fluid conduits lead to face ends of the magnetic armature, which is sealed on its circumference side. When the seat valve is partially open, a pressure is produced in a partial valve chamber by means of a shaping of the valve seat as a hollow cone and of the closing member as a flattened end ball. In the control chamber remote from the closing member, this pressure leads to a movement of the magnetic armature against the tension of a restoring spring, which results in a reduction of the through flow cross section of the seat valve. The valve is particularly useful 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： 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： 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 fuel injector, in particular, an injector for fuel injection systems of internal combustion engines, having an actuator, which cooperates with a valve needle, has a first valve closure member that is arranged on the valve needle, the valve closure member cooperating with a first valve seat surface on a valve body forming a first sealing seat. A second valve closure member cooperates with a second valve seat surface in the valve seat body forming a second sealing seat. The valve needle, or the first valve closure member, has a limit stop, against which, after a partial stroke of the valve needle, a counter limit stop of the second valve closure member strikes, lifting the second valve closure member from the second sealing seat in response to a further stroke of the valve needle.

摘要： A fuel injector, in particular a fuel injector for fuel injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve closing element that can be actuated by the actuator and that works together with a valve seat face to form a seal seat, and a temperature compensation device. The temperature compensation device has a housing that is elastically deformable along a direction of actuation of the actuator, and has at least one throttle that connects an interior space of the housing with a fuel inlet of the fuel injector. The cross-section of this throttle is dimensioned such that an entry and exit of fuel into the housing of the temperature compensation device is enabled when there is a temperature-caused change in length of components of the fuel injector.

摘要： The invention relates to a hydraulically actuated cutoff valve which is provided as an intake valve for switching between a master cylinder and an intake side of a feed pump of a slip-controlled vehicle brake system. The invention sets forth that the cutoff valve is embodied with a valve closing body that has a valve tappet which passes through an annular actuating element and is in engagement with a rocker element embodied as a cup spring, which rests on an annular pivot bearing. If the actuating element is acted upon by pressure, it presses down an outer edge of the rocker element, and as a result a middle of the actuating element executes a pivoting motion in the opposite direction that closes the cutoff valve. The invention has the advantage of an economical cutoff valve that has only a small number of components, and the invention can be used in a hydraulic vehicle brake system.
