Abstract: A decoupler assembly comprises a torque equalizer and a one-way clutch bearing. The torque equalizer comprises an inner member having a rotational axis, an outer member disposed concentrically and surrounding the inner member, and two arcuate spring elements arranged between the inner member and the outer member, and configured to transmit torque between the inner and outer members. The inner member is rotationally displaceable relative to the outer member at least 30 degrees upon compression of the two arcuate spring elements. The one-way clutch bearing is located in the same radial plane as torque equalizer and rotationally connected to the inner member or the outer member. The one-way clutch bearing comprises an outer race, an inner race, and a plurality of individual wedging locking elements that are disposed between the inner and outer races. The decoupler assembly may comprise a single spiral spring element or a rubber-based spring element.

Abstract: The present invention relates to a level indicator for determining the level of liquid in a container, the level indicator comprising: a floating device comprising a metal; a transmitter arranged to transmit an electromagnetic signal towards the floating device; and a receiver arranged to receive a response signal from the floating device. The floating device is moveable relative to the receiver so that a distance from the floating device to the receiver is altered in response to an altered level of liquid in the container, and wherein the electrical signal is a function of at least said distance. The receiver is electrically connectable to a control unit configurable to determine a position of the floating device relative to the receiver based on the electrical signal. The invention also relates to a system and a tank comprising the level indicator.

Abstract: A combustion engine component comprises an assembly of a belt pulley for driving auxiliary engine equipment and a torsional vibration damper. The assembly is adapted to be fixed on an engine crankshaft, wherein the belt pulley is of a so called decoupling type, arranged to be able to change its rotational angle relative to the crankshaft and the torsional vibration damper. The torsional vibration damper is partially positioned in a corresponding annular recess in the belt pulley, creating an annular cavity in the recess between the torsional vibration damper and the belt pulley. An annular seal ring is positioned in the annular cavity and is arranged to close off at least a part of the annular cavity from the air surrounding the assembly.
