摘要： A control unit (50) makes a single control signal available for driving the through-flow control valves (TEV1, TEV2) (51, 52). Through-flow valve (TEV2) has a larger maximum through flow than through-flow control valve (TEV1). A delay circuit is indicated by the phantom outline (52′) and is mounted at the valve stage TEV2 (52). The delay circuit includes an electric delay element (53) with the aid of which the original control signal is delayed in time by an amount &Dgr;t1 relative to the control signal of control valve (TEV1). The resulting delayed signal is supplied to an AND-gate (54) together with the original control signal. Accordingly, a control signal is present at the output of the AND-gate for the control valve (TEV2). The time delay makes possible the exclusive activation of the through-flow control valve (TEV1) (51) at low pulse duty factors. In this way, a high small quantity meterability is achieved. Starting at a specific pregivable switch-in time, the control valve (TEV2) (52) is switched in so that a very large through flow is possible. The invention thereby makes possible excellent meterability at low as well as at high through flows.

摘要： A method and an apparatus operate a tank system including a tank system of a motor vehicle. The tank system includes a tank for receiving a fluid medium forming a volatile substance and an adsorption filter connected to the tank for receiving the volatile substance which emanates from the tank. A shutoff valve is connected to the adsorption filter and is drivable between an open position and a closed position whereat the tank system is closed off to the ambient. A tank fill-level sensor detects the fill level of the fluid medium in the tank. A fill pipe is connected to the tank for filling with the fluid medium. The fill level is detected while tanking and the shutoff valve is driven into the closed position when the fill level has reached a maximum fill level.

摘要： A solenoid valve, such as, for example, a tank-vent valve f or tank venting in motor vehicles, includes at least one valve orifice forming a sealing seat, and a valve member, which cooperates with the sealing seat for releasing and closing it, the valve member being stressed by at least one spring element and activated by an electromagnet. An essentially unstressed neutral position of at least one additional spring element, which acts upon the valve member in the activation direction, is provided in which the valve member is set apart from the sealing seat. In this manner, the impact of the valve member on the sealing seat, which may be accompanied by distracting noises and wear, is damped.

摘要： A magnet valve according to the related art has a sealing and damping device with an elastic region on which, during operation, a force acts due to different existing pressures that must also be overcome when the armature plate is moved. A magnet valve (1) designed according to the invention has a sealing and damping device (46) with an elastic region (105) that is oriented and designed in relation to a seal seat (103) in such a fashion that the above-described force is offset. As a result, a better characteristic curve of the magnet valve (1) over the existing differential pressure is obtained.

摘要： A simplified, economical, noise-abating mode of securing a unit embodied for instance as a valve. For securing the unit, the unit has a housing with a first portion having a first encompassing outer face and at least one second portion having at least one second encompassing outer face, wherein a first sealing ring can be mounted on the first outer face, and the first portion and first sealing ring can be introduced into a recess of an installation wall. A second sealing ring can be mounted on the second outer face of the second portion, and the second portion and second sealing ring can likewise be introduced into the recess, so that the support of the unit in the recess is effected by means of the first and second sealing rings without the first and second outer faces of the unit resting on inner faces of the recess. The installation wall has a tubular protruberance, into which the recess extends and which is subdivided, for retaining the unit, into a plurality of bendable ring-snap elements, into which the second sealing ring can be snapped when the unit is introduced into the recess. The unit according to the invention and the snap device for the unit are intended in particular for valves for metered introduction of evaporated fuel into an intake conduit of the internal combustion engine.

摘要： A tank vent valve for the metered admixing of volatilized fuel to the fuel/air mixture of an internal combustion engine has a valve housing with inflow and outflow sockets, between which is arranged an electromagnetically operable seated valve, which is spring loaded in the closing direction by a valve closing spring. For the simple design of the tank valve, the valve opening of the seat is arranged as a ring gap nozzle in the return yoke of the electromagnet, and the valve double seat which acts in conjunction with the valve member and which surrounds the ring gap nozzle is arranged on that side of the return yoke which faces the inflow socket. For setting the stroke of the valve member, the hollow cylindrical magnet core of the magnet housing can be threaded by means of an adjusting thread in the magnet housing. Supported on the magnet core is a valve closing spring, which loads the valve member which is formed by the armature of the electromagnet, in the closing direction.
