  • Metering system for reducing pollutants in motor vehicle exhaust gases
    Patent number: 7571603
    Abstract: The invention relates to a metering system for injecting pollutant reducing medium into an exhaust system includes a metering pump, and at least one self-opening nozzle for injecting fluidic media into the exhaust gas system. The nozzle is self-opening with a needle chamber, a nozzle needle and a spring chamber with a spring element. The needle chamber and spring chamber are separated by a flexible membrane which prevents fluidic media from escaping from the needle chamber into the spring chamber, and also permits an excess pressure to prevail in the needle chamber in relation to the spring chamber, causing the nozzle needle to be displaced in opposition to a spring force, thus releasing a nozzle opening. The inventive metering system is cost-effective, robust and can also be used at low operating temperatures.

  • High-pressure pump for a fuel injection system of an internal combustion engine
    Patent number: 7571713
    Abstract: The high-pressure pump has at least one pump element with a pump piston driven in a reciprocating motion and guided displaceably in a cylinder bore of a pump housing part which piston defines a pump work chamber that can be filled with fuel from a fuel inlet via a suction valve in the intake stroke. The suction valve has a pistonlike valve member which has a cylindrical shaft and a head of larger cross section at least the shaft is guided displaceably in a guide bore of a valve housing. The head of the valve member is also guided displaceably in a bore of the valve housing, via guide portions embodied on the valve member and spaced apart from one another in the circumferential direction; between the guide portions, flowthrough portions of reduced cross section compared to the guide portions provide for fuel flow out of the fuel inlet into the pump work chamber.

  • Fuel injection device for an internal combustion engine
    Patent number: 7574297
    Abstract: A fuel injection device comprising a high-pressure pump supplying a fuel to a high-pressure area in which an injector for injecting fuel into an internal combustion engine cylinder is arranged. An electric control unit for controlling fuel injection by at least one injector is provided. A pressure adjusting valve which adjusts a pressure in the high-pressure area and controls a connection between said high pressure area and a low-pressure fuel-filled area is controlled by the control unit. When the pressure adjusting valve is not controlled by the control unit it is placed in an open switching position in such a way that the connection between the high- low-pressure areas is opened, thereby preventing a gas formation in the high pressure area when the internal combustion engine is switched off and the fuel is cooled.

  • Device for introducing goods to be packed into packaging containers, especially folding boxes
    Patent number: 7549265
    Abstract: A device (10) for introducing goods to be packed (1, 3) into a packaging container (5) comprises transport devices (11, 15) for the packaging container (5) and the goods to be packed (1, 3). The goods to be packed (1, 3) are compressed by means of pressure elements (25), in order to be introduced into the packaging container (5). The pressure element (25) is guided on a carrier element (32) in a displaceable manner, in order to avoid damage caused by the occurrence of an excess load. Due to the mobility on the carrier element (32), only very small masses are displaced in the event of an excess load, such that the excess load protection device reacts in a reliable manner, and the device (10) has a relatively simple construction.
