  • Patent number: 7086302
    Abstract: Apparatus for reducing backlash in a gear wheel that includes at least two interacting gear rims that rotate in relation to one another. An adjusting mechanism is located between the gear rims for adjusting the relative angle of rotation of the gear rims about a common axis of rotation. Each adjusting mechanism includes an hydraulic cylinder connected to a pressure medium source and which is arranged to act between the two gear rims in such a manner that a force arises that tends to displace one gear rim in relation to the other about the axis of rotation. Each of the hydraulic cylinders extends at an angle to a disk plane and is supported on a part-spherical foot portion in a bowl-shaped seat in one gear rim and a corresponding part-spherical head portion in a bowl-shaped seat in the other gear rim.

  • Patent number: 6895753
    Abstract: Apparatus and method for supplying sealing air to an exhaust turbine (15) that interacts with an internal combustion engine for turbo-compound operation in a vehicle. Exhaust gases from the internal combustion engine are received in an exhaust system having a supercharger turbine (11) and which drives a compressor (13) for the engine combustion air. Residual energy in the exhaust gas flow is recovered via the exhaust turbine (15) for transfer to the crankshaft of the internal combustion engine. The exhaust turbine (15) is supported in a bearing housing (32), which is fed with sealing air via a fluid line (36). The exhaust system includes an exhaust brake throttle (16) having an exhaust gas pressure regulator (22) for regulating the exhaust brake pressure. The exhaust gas pressure regulator (22) is connected via a compressed air line (28) to a compressed air source (29, 30), which can be connected in parallel to the bearing housing (32) via a prioritizing valve (35) and a compressed air line (36).

  • Patent number: 6802303
    Abstract: Method and device (15) for pressure control in a combustion engine (1) with a crankcase (11) to which crankcase gases are guided during operation of the engine. The valve device (15) is adapted for detecting the current pressure in the crankcase (11) and for opening and closing, respectively, a connection (35) between the crankcase (11) and a suction pipe (9) of the engine depending on the detected pressure. The valve device (15) includes a first valve (19) which is adapted for assuming a condition between a first, opened position and a second, closed position depending on the detected pressure in the crankcase (11), and a second valve (20) which is adapted for assuming a condition between a first, opened position and a second, closed position depending on the condition of the first valve (19). The invention also relates to a method for such pressure control.

  • Patent number: 6792904
    Abstract: Method and arrangement for engine breaking in motor vehicles having an internal combustion engine with at least one cylinder, at least one exhaust valve at the cylinder and a rocker arm (4) for activation of the exhaust valve. The rocker arm (4) is arranged on a hollow rocker arm shaft (5) and arranged to be effected by ridges (2a, 2b, 2c) on a camshaft (2), the device additionally having a control valve (15, 16) for controlling the oil pressure in the rocker arm shaft (5), and means (6; 14) receptive to an increase of the oil pressure in the rocker arm shaft (5) being integrated in the rocker arm (4) for absorbing a play between the rocker arm (4) and the exhaust valve in the case of increase oil pressure. At least one of the ridges (2b, 2c) causes opening of the exhaust valve with an engine breaking effect.
