  • Main element for an electrical machine
    Patent number: 7705511
    Abstract: A main element which can be used as a rotor or stator for an electrical machine has a short-circuit ring and radially protruding teeth formed integrally onto the short-circuit ring, which teeth are offset from one another about circumferential angles. To make it possible to press a main element of relatively great axial length of SMC material with the required high material density, the SMC body is subdivided into a plurality of separately manufactured modules, placed against one another in axially aligned fashion, two each of which modules are embodied identically and on being placed against one another are rotated 180° in the plane defined by the module axes. Each separately pressed module, to achieve the required density, has a high aspect ratio, and for pressing the plurality of modules, only two press molds are required.

The valve is partially placed inside a valve block, in which an inlet borehole and an outlet borehole for a hydraulic fluid are made. The hydraulic part comprises a valve element inside of which a transversal borehole is made that communicates with the inlet borehole. In addition, a number of longitudinal boreholes, which are connected to the outlet borehole, are made in the valve element. The transversal borehole and the longitudinal boreholes are connected via a closing element. The valve enables a controlled opening and closing of the closing element thereby making a low-noise switching of the valve possible.

  • Method and apparatus for indirectly ascertaining the cylinder pressure in piston engines
    Patent number: 7654132
    Abstract: In a method for indirectly ascertaining the cylinder pressure during the operation of piston engines by measuring cylinder pressure-dependent parameters at crankshaft bearings of the piston engine, one essential feature is that the force which is introduced by the main bearings of the crankshaft into an engine housing is measured. For performing the method, sensors for obtaining cylinder pressure-correlating signals are disposed on the bearing screws, and that the signals generated by the sensors are carried to the outside.

  • Fuel pump for a fuel system of an internal combustion engine
    Patent number: 7654249
    Abstract: The invention relates to a fuel pump for a fuel system of an internal combustion engine, having a housing and a housing cap joined to the housing. In order to create a fuel pump which in its operation generates little airborne sound, structure-borne sound (vibration amplitudes) and pulsations in a low-pressure region of the fuel pump, it is proposed that the housing cap has at least one damping element, which is embodied as a sandwich construction having at least a first cover layer, a second cover layer, and a damping connection layer disposed between them. The damping connection layer has a markedly higher elasticity and/or higher material damping than the two cover layers, which may be constructed of sheet metal or the housing cap itself.
