Abstract:
An electric motor vehicle coolant pump for cooling an internal combustion engine of a motor vehicle includes a pump housing and a rotor rotatably supported in the pump housing. The rotor comprises a motor rotor configured to be substantially pot-shaped. The motor rotor comprises a pot bottom and a ferromagnetic substance so as to be magnetized in at least a bipolar manner. A pump rotor comprises a plurality of rotor blades and an annular cover ring arranged on distal ends of the plurality of rotor blades. The plurality of rotor blades are configured to stand directly on the pot bottom of the motor rotor. The pump rotor and the motor rotor are each integral plastic material parts separately produced by an injection molding. The pump rotor and the motor rotor are made from different materials. The pump rotor is not ferromagnetic.
Abstract:
A pressurized container includes two plastic casings (12, 14) and produces a leakproof container or storage arrangement which is economical to produce. A gap opening (24) between the casings (12, 14) extends up to a point at which the casings (12, 14) are positioned together in a coaxial manner. An external support ring (22) with a wedge-shaped tapering (26) extends to that point and is embodied as an individual piece or has at least two metal, ring-shaped individual segments (28, 30).
Abstract:
The invention relates to a method and a system for automatic extraction of process goals from a semantically annotated structured process model comprising model elements named by natural language expressions and annotated with semantic linkages to a reference process ontology comprising the steps of:splitting said process model having at least one end event into partial process models provided for each end event of said process model;annotating the model elements of each partial process model with a process goal extracted from said model element; anddecoupling of the process goals from each annotated partial process model to generate a hierarchical process goal tree for each annotated partial process model.
Abstract:
The invention relates to an isolating switch system. The isolating switch system includes an isolating switch for interrupting a main line running between an electric power source and an electric consumer. The isolation switch is controlled in dependence on an ignition switch. The isolating switch system includes a signal generating unit, a signal detector unit and a signal processing unit. The signal generating device generates an electric signal that can be fed to the electric consumer and conducted to the ignition switch. The electric signal, in dependence on a switching state of the ignition switch can be conducted to the signal detector unit via a conduction path. The signal processing unit, upon detection of the electric signal, causes the isolation switching system to open or close the main circuit line. The electric signal generated by the signal generating unit is a pulsed signal.
Abstract:
A hydroaccumulator, in particular a bladder accumulator, includes a pressurized container (1) and a separation element (5) located in the container to separate a gas chamber (7) lying adjacent to an inlet on the gas side from a fluid chamber (9) lying adjacent to an inlet on the fluid side inlet (3), having a fluid connecting sleeve (11) and a valve arrangement located in the connecting sleeve (11). The valve body (17) has a transversal bore (33). The valve body is pretensioned in an open position which allows the passage of fluid and can be displaced into a closed position by a displacement of the separation element (5). The interior surface (15) of the connecting sleeve (11) lies directly against the valve body (17) and guides the displacement of the body between the open and closed positions. The side of the valve body (17′) that faces the separation element (5) is configured as a planar plate extending partially into the fluid chamber (9). The diameter of the valve body (17) is greater than its height, measured in the direction of displacement of the valve body (17). The valve arrangement has a plate-valve construction of small proportions and can be cost-effectively produced.
Abstract:
A lamp unit for a motor vehicle includes a light source, a substantially plano-convex projection lens, and an identification symbol. The projection lens has the configuration of a spherical segment and a central region, and the identification symbol is disposed in the central region of the planar side of the projection lens. The planar side of the lens faces the light source. A method of making a lamp unit for a motor vehicle includes disposing an identification symbol in a central region of a planar side of a substantially plano-convex projection lens of the lamp unit, wherein the planar side of the lens faces a light source.
Abstract:
A hydraulic accumulator, especially a piston accumulator, includes an accumulator housing (10) with at least one gas chamber (12) and a fluid chamber (14). These chambers are separated from each other by a separating element (16). At least one of these chambers (12, 14) can be filled with a pressure medium or at least partially emptied through at least one valve control unit (26) which has switching valves (28, 30). One switching valve (28) is accommodated in a corresponding valve location (29), and can be moved in the direction of movement of the separating element (16) from an opening position into closing position and vice-versa. Expensive line network between the hydraulic accumulator and the valve control unit is avoided. Sealing or leakage problems, such as are common in a line network, never occur. The valve control unit (26) is accommodated in a valve block (24) which is independent from the housing (10). The valve block (24) has an additional valve location (31) for an additional switching valve (30) for performing another switching task. The valve locations (29, 31) are configured essentially identically and are situated eccentrically in relation to the longitudinal axis (33) of the hydraulic accumulator for modular use of the switching valves (28, 30), which are configured as identical parts.
Abstract:
A device for ventilating a side window of a motor vehicle, especially an automobile, has an air guide channel that is located in a vehicle door or other side component that contains the side window near a lower area of the side window. Air outlets of the guide channel are directed at the side window and are located in an area that faces the inside window. The ventilating device is made, especially in areas visible to vehicle occupants, in a suitable visual design. The air guide channel is formed in a separate channel part that is mounted on the vehicle side component and which contains air outlets that terminate in the vicinity of a gap formed between the vehicle side component and the side window.
Abstract:
The invention relates to an instrument cluster with a surround located in front of the display field, the front surface of the instrument cluster conforming to a predetermined path of an instrument panel. The surround is an independent component releasably fastenable to an instrument cluster, with the back surface of the surround facing the front surface of the instrument panel and running parallel to the front surface of the instrument cluster, and with the front surface of the surround that faces away from the instrument cluster following a path that conforms to the path of the instrument panel in the vicinity of the respective driver's seat. A surround is used for a vehicle with left-hand drive, with the front surface of the surround conforming to the path of the instrument panel, and with another surround being used for a vehicle with right-hand drive, whose front surface conforms to the path of the instrument panel in the vicinity of the right-hand driver's seat.
