Appeal No. 1998-1503
Application No. 08/676,907
Appellant has argued that neither Suquet nor Takahashi is
directed to a reciprocating pump, as claimed. Appellant
explains that while these two references are directed to
devices within the field of fuel injection, they are directed
to the opening and closing of a valve. We agree. The opening
and closing of a solenoid valve, as in Suquet and/or
Takahashi, is determinative of the duration of the time in
which the valve is open/closed. The examiner has pointed to
nothing within the teachings of Suquet or Takahashi that would
indicate that the excitation coil, or inductive load, is also
controlled, in addition to duration of a reference signal, by
the amplitude of the reference signal.
Appellant argues that the opening/closing of a valve in
Suquet and Takahashi allows fuel “already under pressure” to
flow into a combustion chamber. The examiner dismisses this
argument by contending that the argument is not directed to
claimed subject matter. While we agree with the examiner that
the claims say nothing about fuel “already under pressure,” we
believe appellant is merely attempting to draw a distinction
between the operation of a reciprocating pump, as claimed, and
the valve opening and closure taught by Suquet and Takahashi.
