spill valve (46, 47, 48) useless from the point at which the
front face of the plunger passes the passage until the end of
the stroke, as the spill passage would be cut off from the
pump chamber (40, 41, 42). Accordingly, we find that one of
ordinary skill in the art would not have been motivated to
place the spill passage of Masahiko at a point intermediate
the ends of the plunger stroke.
Further, unlike the Abe pump which delivers fuel directly
to the engine, the electronically controlled fuel injectors
(2) of Masahiko, not the fuel pump, determine the injection
pulse to be delivered to the engine. Therefore, Abe would not
have provided any suggestion to one of ordinary skill in the
art to provide a pressure reducing arrangement on the Masahiko
pump to produce a pilot pulse at the output of the pump.
For the foregoing reasons, we also reverse the examiner's
rejection of claim 23, and claims 25 and 26 which depend
therefrom.
CONCLUSION
To summarize, the decision of the examiner to reject
claims 1 and 2 under 35 U.S.C. § 102 and claims 3 through 6,
23 and 25 through 27 under 35 U.S.C. § 103 is reversed.
