Application No. 08/399,715
This is a decision on an appeal from the examiner’s final
rejection of claims 1 through 20. No other claims are pending2
in the application.
Appellant’s invention relates to “an arrangement for the
relative adjustment of the rotation angle of a control shaft
[2] with respect to a driving wheel [4], particularly for an
internal combustion engine” (specification, page 1). An
element (10) having one set of teeth engaging teeth on the
driving wheel (4) and another set of teeth engaging teeth on a
part (8) fixed to the control shaft (2) is axially displaceable
to angularly adjust the driving wheel with respect to the
control shaft. In the illustrated embodiment, the control
shaft has a flange (11) disposed on one side of the driving
wheel to act as a stop for limiting axial movement of the
driving wheel in one direction. On the other side of the
driving wheel there is a stop ring (12), a prestressed
diaphragm spring (15) and a wear ring (16). The wear ring
seats against a side face of the driving wheel, and the
diaphragm spring is confined between the stop ring and the wear
2Claim 1 has been amended subsequent to the final
rejection.
