Abstract
A rotary element dynamic imbalance determining apparatus includes a spindle having a first end for removably supporting a rotary element the imbalance of which is to be determined, and a housing for rotatably mounting the spindle. An output signal related to imbalance in the supported rotary element is generated as the spindle rotates. A rotary fluid coupling comprises a chamber between the spindle and housing, a port in the housing for coupling the chamber to a source of compressed air and a one-way fluid seal for dividing the chamber into a first portion and a second portion. A passageway extends along the spindle from the second portion to the first end of the spindle to supply inflating air thereto.
