Abstract: A compressor wheel for a compressor of a turbocharger has a hub and a multiplicity of blades on the hub. In intermediate spaces of the multiplicity of blades, a channel is in each case formed between a suction side and a pressure side. The channel guides fluid that flows in axially in relation to a rotation axis radially or radially-axially outward. The hub in relation to the rotation axis is contoured such that the hub has a rotationally symmetrical portion and a non-rotationally symmetrical portion. On the non-rotationally symmetrical portion, a transition between the hub and each of the blades is embodied with a radiused connection and facing the suction side has a region of modified thickness. A region formed by control rays is generated in at least one channel between the suction side and the pressure side on the hub. A method produces the compressor wheel.

Abstract: A voltage converter of a high voltage driver generates a high voltage applied to an electrorheological damper. The voltage converter and the electrorheological damper are electrically connected together through a connecting portion. The connecting portion comprises an electrode pin that connects the voltage converter and an electrode cylinder of the electrorheological damper; a ground pin that connects an external cylinder of the electrorheological damper and ground, and a ground detection pin disposed separately from the ground pin and connected to the ground through the external cylinder and the ground pin. When the ground detection pin and the ground are disconnected, the voltage converter discontinues the voltage generation with or without a command (control signal) of a sub-controller.

Abstract: An automation system includes at least one automation object, with a directory for storing object names of the at least one automation object. An object name is assigned a directory entry which includes first information data as a reference to the automation object; second information data as a description of technological functionality; and third information data as a description of interfaces of the automation object. This results in immediate and permanent access to currently created (partial) solutions, so that parallel and/or distributed working on automation objects is possible.

Abstract: The invention relates to a method for the automatic retrieval of engineering data from installations. The engineering and runtime objects are described by a uniform object model. This allows the correspondence between engineering objects and runtime objects to be determined at object level and no information is lost as a result of the mapping. In addition, a direct communication between engineering and runtime objects can take place, which can be utilized when the method is carried out.

As a result, a manufacturer-independent definition of new automation objects, possibly using already existing automation objects, becomes possible, costly separate programming of new automation solutions is no longer necessary at all or is at least significantly simplified.

Abstract: A valve seat insert 10 for use in combination with a cylinder head 12. Insert 10 is disposed within a cavity 24 formed within cylinder head 12 and includes several notches 40 which cooperate with surface 26 within cavity 24 to form a plurality of passages or channels 50 which allow fuel 18 to freely pass between surface 26 and insert 10. Channels 50 are effective to substantially prevent fuel 18 from becoming trapped between insert 10 and cylinder head 12, thereby preventing the formation of corrosive acids and byproducts.

Abstract: A high pressure pump which has a working chamber, which on the one hand, is connected to a low pressure circuit via a solenoid valve and on the other hand, is connected to a high pressure reservoir via a check valve. The solenoid valve has a spring-loaded closing body, which cooperates with a valve seat and together with it, constitutes the check valve. When the magnet is without current, the check function of the closing body is switched off via a valve tappet of the solenoid valve so that even with an initial working stroke of the high pressure pump, the connection to the low pressure circuit is maintained. Only with a supply of current to the solenoid valve executed during the working stroke does the valve tappet allow the closing body to contact its valve seat, whereupon the high pressure delivery then begins. The high pressure pump is designated for use in fuel injection systems of diesel motor vehicle engines.

Abstract: The invention provides a fuel injection pump for internal combustion engines having a high-pressure chamber, which is intermittently brought to high fuel pressure, and which communicates via a pressure line with an injection point of an engine, and having a pressure valve, inserted into the pressure line. This pressure valve comprises a valve body and a valve seat onto which a valve member is pressed by the force of a valve spring. The valve spring is located in a recess of a pressure valve holder, which communicates with the injection line via an axial conduit. A transitional region leading from the diameter of the axial recess to the diameter of the conduit is embodied with a cone shape or a truncated cone shape.

Abstract: A fuel injection pump for internal combustion engines, having a pump piston that reciprocates in a cylinder liner inserted into a pump housing. The pump piston and housing encloses a pump work chamber, and the pump piston has a control recess on its jacket face that communicates with the pump work chamber through a conduit. An oblique groove extends at a predetermined angle from the axis of the pump piston in the jacket face thereof and forms control edges. An annular slide is axially displaceable on the pump piston and includes two diametrically opposed diversion bores. To interrupt the high-pressure pumping to provide a pre-injection quantity and a main-injection quantity, first, second and third pockets are additionally machined into the jacket face of the pump piston. These pockets cooperated with pockets machined in the annular slide and with the control edge formed by the lower face edge of the annular slide to control the fuel flow.

Abstract: A fuel injection pump for internal combustion engines is proposed, having a reciprocating piston that defines a pump work chamber in a pump cylinder and that on its jacket face has a control recess communicating with the pump work chamber, and a control slide is displaceable on the pump piston in order to control the high-pressure pumping. This control slide, which cooperates with the control recess on the pump piston, is actuated via an adjusting lever disposed on an adjusting lever shaft; the adjusting lever shaft is moved by an adjusting lever mounted on it outside the housing. This adjusting lever can be pivoted between two stops; according to the invention, these stops are disposed on a base plate that simultaneously acts as a flange of the adjusting lever shaft bearing bush and that can be moved relative to the pump housing via oblong slots in order to adjust the stops.

The tang is controlled by the rider and a control rod to control the fuel injection quantity.

Abstract: A fuel injection pump for internal combustion engines, having a reciprocating pump piston and an annular slide displaceable on the pump piston and having a control bore which cooperates with a control recess on a pump piston that communicates with the pump work chamber via a conduit. Because of a crooked position of the control bore with respect to the piston axis, an ellipse-like opening cross section is created, which in cooperation with the oblique control edge opens a fast, large opening cross section, by way of which in cooperation with an equal pressure valve disposed in the injection line, the fuel can flow out quickly, and a reliable, fast closure of the injection valve is assured. A pressure holding valve is also provided which opens toward the work chamber.

Abstract: The invention is based on a fuel injection pump having an adjuster, actuatable via an adjusting mechanism; the adjusting mechanism has an adjusting piston which is displaceable in a cylinder and is adjustable counter to a restoring force by a pressure fluid. The delivery of pressure fluid to the adjusting piston is controlled via electric valves, and by means of various geometrically defined adjusting piston positions, exact injection adjustment is possible without requiring technically complicated feedback sensors on the adjuster.
