    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 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 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: A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine encompasses a piezoelectric or magnetostrictive actuator, a valve needle actuable by the actuator, the valve needle cooperating with a valve-closure member to form a sealing seat together with a valve-seat member, and a restoring spring by which the valve needle is acted on in a closing direction. The valve needle is pressure-equalized in that the force exerted by the fuel pressure on the valve needle in the opening direction is approximately equal to the force exerted by the fuel pressure on the valve needle in the closing direction.
