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.

Apparatus for reducing gear train backlash

System and a method for automatically topping up an internal combustion engine () with lubricant. A lubricant container that includes a (), a pipe () which connects the container to the internal combustion engine (), a level pipe () which defines the oil level in a sump () and an apparatus () for transferring lubricant. The apparatus () for transferring lubricant makes it possible to transfer lubricant both from the container () to the internal combustion engine () and from the internal combustion engine () to the container ().

Apparatus for controlling a lubrication fluid level

Apparatus and method for supplying sealing air to an exhaust turbine () 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 () and which drives a compressor () for the engine combustion air. Residual energy in the exhaust gas flow is recovered via the exhaust turbine () for transfer to the crankshaft of the internal combustion engine. The exhaust turbine () is supported in a bearing housing (), which is fed with sealing air via a fluid line (). The exhaust system includes an exhaust brake throttle () having an exhaust gas pressure regulator () for regulating the exhaust brake pressure. The exhaust gas pressure regulator () is connected via a compressed air line () to a compressed air source (), which can be connected in parallel to the bearing housing () via a prioritizing valve () and a compressed air line ().

Exhaust turbine apparatus

A fuel delivery system having a fuel reservoir connected to a suction side of a pump, a fuel delivery line connected to an output side of the pump, a number of fuel injectors connected to the delivery line, and a return line from the injectors to the suction side of the pump. The pump has a housing, a pumping chamber within the housing, a driver rotor and a driven rotor within the pumping chamber, and an input shaft t the housing. The input shaft is arranged such that rotation of the input shaft effects rotation of the driver rotor. The driver rotor is caused to rotate by the input shaft via a magnetic coupling. The magnetic coupling is arranged to slip when a predetermined value of torque is applied across the coupling such that a maximum pressure value of about 12 bar is attained at the output side of the pump.
