Vorrichtung zur AEnderung der zeitlichen Durchflussmenge eines fluessigen Daempfungsmittels bei einem Drehschwingungsdaempfer

摘要

Device for modifying the delivery of a damping fluid for a rotational vibration damper, particularly for piston engines, in whose rotating cylindrical damper housing, connected to the input or output drive shaft, spur gears are borne in a planetary manner and, engaging with a central spur gear seated on the output or input drive shaft, form a gearwheel pump for a closed circuit of the damping fluid, with a storage chamber in the supply line for the damping fluid on the respective pressure side, the storage chamber having a volume which can be modified elastically and a speed-dependent controlled piston valve being provided in the pressure side of the supply line, whose piston is suitable for modifying the cross-section of the supply line, by its axial movement, as a throttle adjuster. ……
