Appeal No. 2006-1447 Παγε 2
Application No. 10/775,881
BACKGROUND
The appellants' invention relates to an air pressure
proportional damper for a shock absorber (specification, page 1).
Claim 1 is representative of the invention, and is reproduced as
follows:
1. An air pressure proportional damper comprising:
a container having a first chamber and a second
chamber;
a piston rod slidingly disposed in the first chamber
of the container;
a piston attached to the piston rod, the piston being
in sliding engagement with walls of the first chamber;
a valve disposed between the first chamber and the
second chamber, the valve regulating fluid flow between the first
chamber and the second chamber through a fluid passage;
a membrane movable between a first position where the
fluid passage is open and a second position where the fluid
passage is closed, the membrane defining an aperture to allow a
specified amount of fluid flow between the first chamber and the
second chamber when the membrane is in the second position;
a pressure signal supplied from an air spring to the
valve;
wherein the valve regulates fluid flow from the first
chamber to the second chamber proportional to the pressure
signal.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
