Abstract
A standby generator includes an air-cooled engine having a crankshaft, an alternator driven by the crankshaft to produce electrical power for distribution from the standby generator, and an engine cooling fan operatively coupled to the crankshaft on a side of the engine driving the alternator.
Claims21
A standby generator comprising:
- an air-cooled engine having a crankshaft,
- an alternator driven by the crankshaft to produce electrical power for distribution from the standby generator, and
- an engine cooling fan operatively coupled to the crankshaft on a side of the engine driving the alternator.
A generator comprising:
- an air-cooled engine;
- an alternator driven by the engine via a shaft extending from the engine to the alternator;
- and
- an engine cooling fan operatively coupled to the shaft between the engine and the alternator;
- and
- wherein the engine cooling fan is coupled to the shaft in a spaced relationship from the alternator so as to create an airflow path to the engine cooling fan that bypasses the alternator.
3 more elements
A standby generator comprising:
- a generator housing having a base, a top, and a plurality of sidewalls defining an interior of the housing, the housing comprising:
- one or more airflow inlets, and
- one or more airflow outlets;
- an engine mounted to the base, the engine comprising:
- a crankcase,
- a crankshaft coupled to the crankcase, and
- an engine fan driven by the crankshaft to cool the engine, the engine fan drawing a first stream of air into the housing through at least one of the one or more airflow inlets and driving the first stream of air out through at least one of the one or more airflow outlets;
- and
- an alternator mounted to the base, the alternator driven by the crankshaft on a side of the engine fan opposite the crankcase.
