Abstract: The ultrasonic atomizer system serves to atomize fuel to be injected into internal combustion engines, thereby forming droplets of identical diameters (d.sub.T). The ultrasonic atomizer system includes an atomizer housing having a pressure chamber into which fuel is delivered under pressure by a pump. An ultrasonic vibrator protudes into the atomizer housing. Transport lines that transmit the vibrations lead from the pressure chamber to nozzles on the air intake tubes of the engine. A plurality of injection ports are provided in each of the nozzles and the streams of liquid emerging from the injection ports of each nozzle are made to undergo a monodisperse disintegration by the vibrations of the ultrasonic vibrator to form droplets of equal diameter (d.sub.T).

Abstract: In a multi-cylinder internal combustion engine having fuel injection, in particular a turbo-engine, having air intake and exhaust gas conduits, a turbocharger and a regulating valve for furnishing combustion air to the exhaust gas conduit when the throttle valve in the air intake conduit is closed partially or entirely, in order to maintain the charge pressure of the turbocharger during overrunning or at partial load with good efficiency of the system. When the regulating valve opens, a portion of the cylinders is not ignited and the remaining portion of the cylinders is ignited at an extremely late instant of ignition, with suitable metering of the fuel injection quantity.

Abstract: A method and an apparatus for controlling the spring stiffness in two bodies or masses that are movable relative to one another and in their absolute positions with variable speeds, in particular in resilient wheel suspension systems for vehicles and the like, wherein the volume positively displaced by a piston in a cylinder pressure chamber can be abruptly switched over into two partial volumes in accordance with load, movement and operating parameters of the vehicle, suspension and wheel as well as vehicle body, with it being possible, with partial volumes communicating with one another, to perform an additional total-volume fine adjustment continuously via a cylinder/piston unit and also in accordance with the parameters mentioned. A suspension concept of this kind, with slow, continuous adaptive adaptation and rapid switchover to greater stiffnesses is augmented by an asymmetrically variable damping and a preferably fast-operating level control means.

The axial fixation of the pressure regulating valve in the holder bushing is effected via a screw connection with a retaining body.

Abstract: A fuel injection system for internal combustion engines is proposed which serves to inject a quantity of fuel adapted to the aspirated air quantity. In the intake tube of the engine, an intake tube section downstream of a throttle valve communicates with an intake tube pressure sensor via a connecting line. The output signal of this intake tube pressure sensor affects the opening duration of the injection valves. In order to reduce the influence of pulsations on the measurement product of the intake tube pressure sensor, a throttle valve is provided which in the presence of the operational engine states of upper partial load and full load reduces the cross section of the connecting line.

Abstract: A brake booster has a first booster cylinder and a booster piston disposed in it for displacing a rod-like master cylinder piston of a master cylinder which supplies at least one brake circuit (I, II), having a tappet for mechanically displacing the first booster piston as needed if the brake boosting is inadequate, and having a brake valve coupled to the tappet and the first booster piston for direction boosting pressure into the first booster cylinder. A second, annular booster piston surrounds the rod-like master cylinder piston and likewise has a booster cylinder. Thsi second booster piston is joined to a pump piston which is likewise annular and sealingly surrounds the rod-like master cylinder piston. When the pressure supply apparatus is in operation, actuation of the brake pedal simultaneously displaces both booster pistons and generates braking pressures in the brake circuits (I, II).

Abstract: An apparatus for separating and erecting foldable boxes has a supply magazine for foldable boxes, a removal device with revolving suction grippers, and an endless conveyor device provided with carriers and blower nozzles, which are disposed laterally of the conveyor apparatus with the blower nozzles arranged to inflate the conveyed foldable boxes. The suction grippers pull the foldable boxes out of the magazine seriatim in the direction in which the foldable boxes extend and transfer them to the conveyor apparatus such that they lie flat on an arc-like stretch. For guiding the chains of the conveyor device and for guiding the foldable boxes in the arc-like stretch, arc-like curved guide rails are disposed on the revolving path of the suction grippers following the magazine. The blower nozzles are associated with a straight stretch of the conveyor device.

Abstract: A centrifugal adjuster for a fuel injection pump governor having a driving part driven at an rpm in synchronism with the engine and having a torsionally elastically coupled flyweight holder guided in a rotational guide. Via a step, beyond a predetermined rotational deflection, the centrifugal adjuster displaces the flyweight holder axially with respect to the driving part, so that a jolt-like stroke effected by means of the step is superimposed on the regulating stroke effected via the flyweights of the centrifugal adjuster whenever the rpm is at a low level, for instance at idling rpm. As a result, a friction that leads to see-sawing of the engine and exhibits pronounced hysteresis is shaken out of the governor.

To enable use of the pull tab as a reclosure element, it has a stopper-like lower extension which has a complemental outline to that of the tear-open portion and on which a shear edge is disposed. The pull tab is firmly connected to the tear-open portion with a narrow strip of a fusing glue.

Abstract: A failsafing device is proposed for an anti-skid system of a tractor-trailer combination. If the trailer anti-skid system fails at the rear axle, instead of shutting off the entire anti-skid system of the trailer, the anti-skid control at the front axle of the trailer is maintained.

Abstract: A fuel injection pump for internal combustion engines which has an rpm-proportional injection onset adjusting device, a pressure control valve controlling the supply pressure (phd f), a cold-start acceleration device having a pressure valve associated with the pressure control valve, and a full-load stop, controlled by an adjustment device, for limiting the maximum full-load quantity injected by the fuel injection pump. The adjustment device has a piston, which is acted upon on one end by the supply pressure in the suction chamber of the injection pump and on the other end by a pressure (p.sub.a) that is made to differ from the supply pressure by means of two separate throttles. The two throttles have the effect that if the pressure valve is closed, the adaptation device is subjected to a differential pressure which is approximately equal to that when the pressure valve is opened, and so the full-load courses attained in normal operation and in cold operation are virtually identical.

Abstract: A fuel injection pump for internal combustion engines is described, which for controlling fuel quantity is provided with control unit that controls an electric final control element, which in turn actuates the regulating member that determines the fuel injection quantity per pump piston supply stroke. The supply of fuel to the pump work chamber is effected from a fuel supply chamber, which is kept at a controlled pressure by a fuel feed pump. To limit the maximum speed of the engine supplied by the fuel injection pump in the event of failure of the control unit, a valve is provided in the intake line of the fuel feed pump. Using this valve, the flow cross section of the intake line can be varied or closed. By means of the modification of the fuel pressure in the fuel supply chamber effected thereby, a control of the fuel injection quantity that is not dependent on the position of the quantity-determining member is attained.
