  • Publication number: 20200393005
    Abstract: A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier. The input part includes a rotor carrier, an inner-plate carrier separate from the rotor carrier, and an inner plate rotationally fastened to the inner-plate carrier. The spring device is for bracing the outer plate and the inner plate together with a pressing force to close the friction clutch. The connecting means includes an actuating surface via which the friction clutch can be actuated by an actuating device.

  • Patent number: 10605504
    Abstract: A ducted separator in a compressor-based cooling assembly is connected to an oil/gas outlet of the compressor. The ducted separator is a pipe with at least one bend in it which collects oil in a manner which can achieve 98% oil carry over efficiency. The ducted separator may optionally be connected to a second phase separator such as a centrifugal cylinder. In that case, the height of the centrifugal cylinder can be significantly reduced compared with conventional arrangements. Alternatively, a simpler impingement surface such as one or more baffles may be used as the second phase separator or just a collection chamber.

  • Patent number: 10570874
    Abstract: A method of operating an internal combustion engine with at least one piston-cylinder unit, and preferably a plurality of the piston-cylinder units, whereby, in a detection mode of the internal combustion engine one or more knock-promoting measures are taken until knocking has occurred in at least one piston-cylinder unit, and the measure(s) is/are intensified until a termination criterion is reached, whereby it is detected in which of the piston-cylinder units knocking has occurred, and whereby, in piston-cylinder units detected as knocking, the ignition time for a normal operating mode of the internal combustion engine is retarded.

  • Patent number: 9187054
    Abstract: A cross member for arrangement on a bumper system for a motor vehicle includes a single-piece open profile part made of uniform material and having a U-shaped cross section to define a first opening. The profile part has a curvature directed in a travel direction of the motor vehicle and includes a center zone having a second opening which is configured to point backwards in the travel direction, and end zones which have each an attachment area for a crash box and in which the first opening is configured to point forwards in the travel direction.

  • Patent number: 8702408
    Abstract: A slide for use in a single screw compressor is disclosed. The screw compressor is arranged to vent the flutes of its main rotor at all times, without having to provide a check valve in the discharge port of the main rotor casing. An additional outlet port in the casing vents gas from the discharge ends of the flutes into the body of the slide instead of to the discharge port. The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the disclosed slide further allows the use of an offset discharge port in the casing, in relation to the main rotor.

  • Patent number: 8622446
    Abstract: A bumper for a motor vehicle includes a crossbeam having a hat profile defined by a bottom wall, legs respectively adjoining the bottom wall, and flanges respectively extending from the legs. The hat profile has sections of varying cross sectional configuration in a longitudinal direction. A face plate closes the hat profile to define a hollow space, with the crossbeam being mountable with the face plate such as to point outwards. An upper one of the legs has a width which is greater than a width of a lower one of the legs in a center section of the crossbeam. The crossbeam has curved ends oriented in a direction of the motor vehicle, and the face plate includes in the center section a stiffening embossment which is oriented into the hollow space defined by the hat profile and the face plate.

  • Patent number: 8419091
    Abstract: A bumper for an automobile includes a crossbeam which is formed from at least two separate hollow profiles, wherein the hollow profiles abut one another along a longitudinal wall and are joined with one another. The abutting longitudinal walls form a double web oriented in the longitudinal direction of the automobile. The hollow profiles may have an identical cross-sectional configuration. The hollow profiles may be roll-formed or extruded. The modular construction of the crossbeam from separate hollow profiles allows a lightweight construction and allows the load characteristic of the crossbeam to be functionally adapted to different requirements depending on the vehicle or vehicle class.

The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the slide further allows the use of an offset •? discharge port in the casing, in relation to the main rotor. This means that pressure acting through the discharge port in use of the compressor tends to press the slide against another structure than the main rotor, for instance a bearing housing, giving better support to the slide. The slide also provides an improved oil delivery arrangement.
