Generator including vertically shafted engine
View Patent ↗A generator positionable on a support surface and including a frame, an internal combustion engine coupled to the frame, an electrical energy source, a fuel tank, and an output unit. The one-piece mounting member is coupled to the frame and has mounting arms that each provide a frame mount, an engine mount, and a source mount. The internal combustion engine is coupled to the mounting member and includes an output shaft that extends through a central portion and that is substantially normal to the support surface during generator operation. The electrical energy source has a rotor coupled to the output shaft for rotation therewith, and a stator coupled to the mounting member. The fuel supply supplies fuel to the engine, and the output unit communicates with at least one of the engine and the energy source.
1. A generator positionable on a support surface, the generator comprising:
a frame;
a mounting member coupled to the frame and having a central portion defining a plurality of airflow openings, a first side, and a second side;
an internal combustion engine coupled to the first side of the mounting member and including an output shaft that extends through the central portion and is substantially normal to the support surface during generator operation;
an electrical energy source having a rotor coupled to the output shaft for rotation therewith, and a stator coupled to the second side of the mounting member, the stator defining an air inlet opening adjacent the support surface;
an enclosure having at least first and second sidewalls and a top wall that cooperate to surround the engine, the energy source, and the mounting member, the enclosure defining a first air flow path that guides air from the top wall toward the engine, and from the engine toward the first sidewall, and a second air flow path that guides air from the second sidewall toward the air inlet opening defined by the stator, and through the stator toward the airflow openings in the mounting member.
2. The generator of claim 1 , wherein the enclosure includes an intake manifold extending between the top wall and an upper portion of the engine for guiding air from the air flow apertures in the top wall toward the engine during generator operation.
3. The generator of claim 1 , wherein the enclosure includes an engine exhaust duct extending between the engine and one of the sidewalls for guiding air from the engine toward the one sidewall during generator operation.
4. The generator of claim 3 , wherein the engine includes a muffler positioned at least partially within the engine exhaust duct, and wherein air flowing away from the engine toward the first sidewall flows over the muffler.
5. The generator of claim 1 , wherein the enclosure includes a source inlet manifold extending between the second sidewall and the air inlet opening for guiding air toward the air inlet opening during generator operation.
