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.

摘要： An injection valve for fuel injection systems of internal combustion engines which is used for injection of fuel into the intake tube. The injection valve includes a valve housing in which a core that cooperates with an armature is located. Connected to the valve housing is a nozzle body in which a conical valve seat face is formed, with which a sealing section of a valve needle actuated by the armature cooperates. The valve needle is guided by guide sections in a guide bore of the nozzle body, and upstream of the sealing section, the valve needle has a cylindrical section which protrudes through a central opening of an insert body. The insert body rests with a jacket sealing face on the valve seat face and has flow openings that lead from upstream to downstream of the insert body and are aimed at the valve seat face.

摘要： The invention relates to an injection valve for internal combustion engine fuel injection systems. The valve is designed to inject fuel into the intake manifold. The valve comprises a valve housing containing a core, with which an armature cooperates. A nozzle body with a valve seat is connected to the valve housing. A sealing seat of a valve needle guided in the nozzle body cooperates with the valve seat. The valve needle is guided by first and second guide parts in a guide bore of the nozzle body and the second guide part, which is adjacent to the sealing seat in the upstream direction, is provided with metering bores. These metering bores are inclined such that they produce a spinning effect when the valve is open, thereby providing for good preparation of the fuel. According to the invention, each metering bore discharges immediately proximate to and directly upstream of, the sealing seat.
