Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
130 words
In an internal combustion engine having a crankshaft, a ring gear fixed to a flywheel of said crankshaft and a starter motor including a pinion having a diameter substantially less than said ring gear and means for selectively engaging said starter motor pinion with said ring gear, an auxiliary power output device comprising: an auxiliary power output shaft driving an auxiliary device; a pulley fixed to said output shaft; and a belt drivingly wound between said ring gear and said pulley, wherein said ring gear, said starter motor and said pulley are relatively positioned such that said starter motor pinion is spaced from and surrounded by said belt and is directly engageable with said ring gear at a circumferential position where said belt does not wind around said ring gear.
Claim 2
Dependent Claim
