  • Valve for an exhaust system of an internal combustion engine
    Patent number: 9638332
    Abstract: A valve for an exhaust system of an internal combustion engine includes a housing which contains a passage for conducting exhaust gases. In the passage is arranged a closing body with which the passage can be closed. The closing body is fastened in a rotationally fixed manner to a shaft, which is mounted rotatably in the housing, and can be pivoted together with the shaft about the rotation axis of the shaft. The closing body has a partition, which runs perpendicularly to the rotation axis of the shaft, and has a circular outer contour which is sealed off from the housing and divides the passage into a first duct and a second duct. When the closing body is in the closed position both the first and second ducts are closed. When the closing body is in an open position the exhaust gasses can pass through the first and second ducts.

  • Wear-resistant chain pin
    Patent number: 9638284
    Abstract: Problem. To provide a chain pin which makes it possible to improve wear resistance even in an environment in which degraded oil is used. Solution. A large number of pins are mixed/agitated together with a particle mixture including a penetrant comprising chromium (Cr) powder and tungsten carbide (WC) powder, and an iron chloride (FeCl3) catalyst, and WC particles penetrate the surface of the pins together with chromium carbide (CrC). As a result, a chromium carbide layer in which WC particles are diffused in a CrC layer (CrC—WC layer) is formed on the outermost surface part of the steel forming the parent material of the pins.

  • Axial bearing arrangement
    Patent number: 9638244
    Abstract: A hydrodynamic axial bearing is provided with segments arranged on a circular ring on axial bearings, wherein a plurality of pressure fields are built up. The length of the individual segments is defined in the circumferential direction, between a first edge and a second edge. The first edge delimits the wedge surface of the segments. In fast-rotating bearings, the ratio of segment width to segment length has a decisive influence on the attainable load-bearing capacity and resulting friction losses. The load-bearing capacity and friction losses are improved by increasing the segment length more intensely with increasing radius. The first edge does not run straight but rather has steps, is arcuate or has linear portions with different gradients.
